mirrors: distinguish between source/binary mirror; simplify schema (#34523)
Allow the following formats:

```yaml
mirrors:
  name: <url>
```

```yaml
mirrors:
  name:
    url: s3://xyz
    access_pair: [x, y]
```

```yaml
mirrors:
  name:
    fetch: http://xyz
    push:
      url: s3://xyz
      access_pair: [x, y]
```

And reserve two new properties to indicate the mirror type (e.g.
mirror.spack.io is a source mirror, not a binary cache)

```yaml
mirrors:
  spack-public:
    source: true
    binary: false
    url: https://mirror.spack.io
```

installer: Improve status reporting (#37903)
Refactor `TermTitle` into `InstallStatus` and use it to show progress
information both in the terminal title as well as inline. This also
turns on the terminal title status by default.

The inline output will look like the following after this change:
```
==> Installing m4-1.4.19-w2fxrpuz64zdq63woprqfxxzc3tzu7p3 [4/4]
```

Allow configurable stage names (#36509)
Add `config:stage_name` which is a Spec format string that can
customize the names of stages created by Spack. This was primarily
created to allow generating shorter stage names on Windows (along
with `config:build_stage`, this can be used to create stages with
short absolute paths).

By default, this is not set and the prior name stage format is used.

This also removes the username component that is always added to
Stage paths on Windows (if users want to include this, they can
add it to the `build_stage`).

WGL package: correct libs/headers detection (#35113)
Corrects libs detection with a more specific root, otherwise there
can be inconsistencies between version of WGL requested and the
version picked up by `find_libraries`.

Corrects headers detection - win-sdk, win-wdk, and WGL headers all
exist under the same directory, so we can compute the headers for WGL
without querying the spec for win-sdk (which causes errors).

This commit also removes the `plat` variant of `wgl`, which is
redundant with the Spec's target.

concretizer: add mode to reuse dependencies only (#30990)
This adds a new mode for `concretizer:reuse` called `dependencies`,
which only reuses dependencies. Currently, `spack install foo` will
reuse older versions of `foo`, which might be surprising to users.

Allow users to specify root env dir (#32836)
* Allow users to specify root env dir

Environments managed by spack have some advantages over anonymous Environments
but they are tucked away inside spack's directory tree. This PR gives
users the ability to specify where the environments should live.

See #32823

This is also taken as an opportunity to ensure that all references are to "managed environments",
rather than "named environments". Prior to this PR some references to the latter persisted.

Increase db timeout 3s -> 60s (#35517)
When running many concurrent spack install processes that need to write
to the db, Spack regularly times out. This is because writing to the DB
after another process has written to it requires deserialization of the
db, mutating it in memory, and serializing it again, which takes some
time. On top of that, I believe there's a 1 second retry when a write
lock cannot be obtained, so I think this means only 3 processes can
really write to the DB at the same time before timing out.

Control Werror by converting to Wno-error (#30882)
Using `-Werror` is good practice for development and testing, but causes us a great
deal of heartburn supporting multiple compiler versions, especially as newer compiler
versions add warnings for released packages.  This PR adds support for suppressing
`-Werror` through spack's compiler wrappers.  There are currently three modes for
the `flags:keep_werror` setting:

* `none`: (default) cancel all `-Werror`, `-Werror=*` and `-Werror-*` flags by
  converting them to `-Wno-error[=]*` flags
* `specific`: preserve explicitly selected warnings as errors, such as
  `-Werror=format-truncation`, but reverse the blanket `-Werror`
* `all`: keeps all `-Werror` flags

These can be set globally in config.yaml, through the config command-line flags, or
overridden by a particular package (some packages use Werror as a proxy for determining
support for other compiler features).  We chose to use this approach because:

1. removing `-Werror` flags entirely broke *many* build systems, especially autoconf
   based ones, because of things like checking `-Werror=feature` and making the
   assumption that if that did not error other flags related to that feature would also work
2. Attempting to preserve `-Werror` in some phases but not others caused similar issues
3. The per-package setting came about because some packages, even with all these
   protections, still use `-Werror` unsafely.  Currently there are roughly 3 such packages
   known.

concretizer:unify:true as a default (#31787)
`spack env create` enables a view by default (in a weird hidden
directory, but well...). This is asking for trouble with the other
default of `concretizer:unify:false`, since having different flavors of
the same spec in an environment, leads to collision errors when
generating the view.

A change of defaults would improve user experience:

However, `unify:true` makes most sense, since any time the issue is
brought up in Slack, the user changes the concretization config, since
it wasn't the intention to have different flavors of the same spec, and
install times are decreased.

Further we improve the docs and drop the duplicate root spec limitation

Experimental binding of shared ELF libraries (#31948)
Adds another post install hook that loops over the install prefix, looking for shared libraries type of ELF files, and sets the soname to their own absolute paths.

The idea being, whenever somebody links against those libraries, the linker copies the soname (which is the absolute path to the library) as a "needed" library, so that at runtime the dynamic loader realizes the needed library is a path which should be loaded directly without searching.

As a result:

1. rpaths are not used for the fixed/static list of needed libraries in the dynamic section (only for _actually_ dynamically loaded libraries through `dlopen`), which largely solves the issue that Spack's rpaths are a heuristic (`<prefix>/lib` and `<prefix>/lib64` might not be where libraries really are...)
2. improved startup times (no library search required)

Windows: fix library loading and enable Clingo bootstrapping (#33400)
Changes to improve locating shared libraries on Windows, which in
turn enables the use of Clingo. This PR attempts to establish a
proper distinction between linking on Windows vs. Linux/Mac: on
Windows, linking is always done with .lib files (never .dll files).
This somewhat complicates the model since the Spec.lib method could
return libraries that were used for both linking and loading, but
since these are not always the same on Windows, it was decided to
treat Spec.libs as being for link-time libraries. Additional functions
are added to help dependents locate run-time libraries.

* Clingo is now the default concretizer on Windows
* Clingo is now the concretizer used for unit tests on Windows
* Fix a permissions issue that can occur while moving Git files during
  fetching/staging
* Packages can now implement "win_add_library_dependent" to register
  files/directories that include libraries that would need to link
  to dependency dlls
* Packages can now implement "win_add_rpath" to register the locations
  of dlls that dependents would want to load
* "Spec.libs" on Windows is updated to return link-time libraries
  (i.e. .lib files, rather than .dll files)
* PackageBase.rpath on Windows is now updated to return the most-likely
  locations where .dlls will be found (which is generally in the bin/
  directory)

Update the binary index before attempting direct fetches (#32137)
"spack install" will not update the binary index if given a concrete
spec, which causes it to fall back to direct fetches when a simple
index update would have helped. For S3 buckets in particular, this
significantly and needlessly slows down the install process.

This commit alters the logic so that the binary index is updated
whenever a by-hash lookup fails. The lookup is attempted again with
the updated index before falling back to direct fetches. To avoid
updating too frequently (potentially once for each spec being
installed), BinaryCacheIndex.update now includes a "cooldown"
option, and when this option is enabled it will not update more
than once in a cooldown window (set in config.yaml).

OpenGL restructure (#31748)
* OpenGL: Restructures the OpenGL packages

This provides concrete glx and osmesa packages which delegate to
virtual libglx and libosmesa packages provided by mesa. This was
necessary because GLX and OSMesa both provide gl implementations but
with mesa providing the girtual gl package there was no way to properly
distinguish which of the two opengl implementations was beiing requested
when querying the spec['gl'] dependency.  This additional level of
indirection allows for that.

* OpenGL: Adjust downstream dependents of OpenGL for the restructure

This implements the necessary fixes in the packages that depend on
OpenGL to work with the restructuring.  This also attempts to create a
consistent variant for specifying glx or osmesa.

Add a command to generate a local mirror for bootstrapping (#28556)
This PR builds on #28392 by adding a convenience command to create a local mirror that can be used to bootstrap Spack. This is to overcome the inconvenience in setting up this mirror manually, which has been reported when trying to setup Spack on air-gapped systems.

Using this PR the user can create a bootstrapping mirror, on a machine with internet access, by:

% spack bootstrap mirror --binary-packages /opt/bootstrap
==> Adding "clingo-bootstrap@spack+python %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding "gnupg@2.3: %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding "patchelf@0.13.1:0.13.99 %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding binary packages from "https://github.com/alalazo/spack-bootstrap-mirrors/releases/download/v0.1-rc.2/bootstrap-buildcache.tar.gz" to the mirror at /opt/bootstrap/local-mirror

To register the mirror on the platform where it's supposed to be used run the following command(s):
  % spack bootstrap add --trust local-sources /opt/bootstrap/metadata/sources
  % spack bootstrap add --trust local-binaries /opt/bootstrap/metadata/binaries
The mirror has to be moved over to the air-gapped system, and registered using the commands shown at prompt. The command has options to:

1. Add pre-built binaries downloaded from Github (default is not to add them)
2. Add development dependencies for Spack (currently the Python packages needed to use spack style)

* bootstrap: refactor bootstrap.yaml to move sources metadata out

* bootstrap: allow adding/removing custom bootstrapping sources

This operation can be performed from the command line since
new subcommands have been added to `spack bootstrap`

* Add --trust argument to spack bootstrap add

* Add a command to generate a local mirror for bootstrapping

* Add a unit test for mirror creation

Add a Lua build-system (#28854)
Reworking lua to allow easier substitution of the base lua implementation.

Also adding in a maintained version of luajit and re-factoring the entire stack 
to use a custom build-system to centralize functionality like environment 
variable management and luarocks installation.

The `lua-lang` virtual is now versioned so that a package that requires 
Lua 5.1 semantics can get any lua, but one that requires 5.2 will only 
get upstream lua.

The luaposix package requires lua-bit32, but only when built with a 
lua conforming to version 5.1.  This adds the package, and the 
dependencies, but exposed a problem with luarocks dependency 
detection.  Since we're  installing each package in its own "tree" and 
there's no environment  variable to list extra trees, spack now 
generates a luarocks config  file that lists all the trees of all the 
dependencies, and references  it by setting `LUAROCKS_CONFIG` 
in the build environment of every LuaPackage.  This allows luarocks 
to find the spack installed  dependencies correctly rather than 
trying (and failing) to download them.

Deprecate top-level module config (#28659)
* Ignore top-level module config; add auto-update

In Spack 0.17 we got module sets (modules:[name]:[prop]), and for
backwards compat modules:[prop] was short for modules:default:[prop].

But this makes it awkward to define default config for the "default"
module set.

Since 0.17 is branched off, we can now deprecate top-level module config
(that is, just ignore it with a warning).

This PR does that, and it implements `spack config update modules` to
make upgrading easy (we should have added that to 0.17 already...)

It also removes references to  `dotkit` stuff which was already
deprecated in 0.13 and could have been removed in 0.14.

Prefix inspections are the only exception, since the top-level prefix inspections
used for `spack load` and `spack env activate`.

of Intel compilers in their own compiler block by adding ifx.exe to the
fc/f77_name blocks inside intel.py

800ed16e7a config: add a new concretizer config section
The concretizer is going to grow to have many more configuration,
and we really need some structured config for that.

* We have the `config:concretizer` option that chooses the solver,
  but extending that is awkward (we'd need to replace a string with
  a `dict`) and the solver choice will be deprecated eventually.

* We have the `concretization` option in environments, but it's
  not a top-level config section -- it's just for environments,
  and it also only admits a string right now.

To avoid overlapping with either of these and to allow the most
extensibility in the future, this adds a new `concretizer` config
section that can be used in and outside of environments. There
is only one option right now: `reuse`.  This can expand to include
other options later.

Likely, we will soon deprecate `config:concretizer` and warn when
the user doesn't use `clingo`, and we will eventually (sometime later)
move the `together` / `separately` options from `concretization` into
the top-level `concretizer` section.

This commit just adds the new section and schema. Fully wiring it
up is TBD.

- [x] Fix hard-coded `~/.spack` references in `install_test.py` and `monitor.py`

Also, if `SPACK_DISABLE_LOCAL_CONFIG` is used, there is the issue that
`$user_config_path`, when used in configuration files, makes no sense,
because there is no user config scope.

Since we already have `$user_cache_path` in configuration files, and since there
really shouldn't be *any* data stored in a configuration scope (which is what
you'd configure in `config.yaml`/`bootstrap.yaml`/etc., this just removes
`$user_config_path`.

There will *always* be a `$user_cache_path`, as Spack needs to write files, but
we shouldn't rely on the existence of a particular configuration scope in the
Spack code, as scopes are configurable, both in number and location.

- [x] Remove `$user_config_path` substitution.
- [x] Fix reference to `$user_config_path` in `etc/spack/deaults/bootstrap.yaml`
      to refer to `$user_cache_path`, which is where it was intended to be.

ae6e83b1d5 config: overrides for caches and system and user scopes (#26735)
Spack's `system` and `user` scopes provide ways for administrators and
users to set global defaults for all Spack instances, but for use cases
where one wants a clean Spack installation, these scopes can be undesirable.
For example, users may want to opt out of global system configuration, or
they may want to ignore their own home directory settings when running in
a continuous integration environment.

Spack also, by default, keeps various caches and user data in `~/.spack`,
but users may want to override these locations.

Spack provides three environment variables that allow you to override or
opt out of configuration locations:

 * `SPACK_USER_CONFIG_PATH`: Override the path to use for the
   `user` (`~/.spack`) scope.

 * `SPACK_SYSTEM_CONFIG_PATH`: Override the path to use for the
   `system` (`/etc/spack`) scope.

 * `SPACK_DISABLE_LOCAL_CONFIG`: set this environment variable to completely
   disable *both* the system and user configuration directories. Spack will
   only consider its own defaults and `site` configuration locations.

And one that allows you to move the default cache location:

 * `SPACK_USER_CACHE_PATH`: Override the default path to use for user data
   (misc_cache, tests, reports, etc.)

With these settings, if you want to isolate Spack in a CI environment, you can do this:

   export SPACK_DISABLE_LOCAL_CONFIG=true
   export SPACK_USER_CACHE_PATH=/tmp/spack

This is a stop-gap approach until we have figured out how to deal with
the system and user config scopes more generally, as there are plans to
potentially / eventually get rid of them.

**User config**

Spack is a bit of a pain when you have:

- a shared $HOME folder across different systems.
- multiple Spack versions on the same system.

**System config**

- On shared systems with a versioned programming environment / toolkit,
  system administrators want to provide config for each version (e.g.
  21.09, 21.10) of the programming environment, and the user Spack
  instance should be able to pick this up without a steep learning
  curve.
- On shared systems the user should be able to opt out of the
  hard-coded config scope in /etc/spack, since it may be incompatible
  with their particular instance. Currently Spack can only opt out of all
  config scopes through overrides with `"config:":`, `"packages:":`, but that
  also drops the defaults config, which would have to be repeated, which
  is undesirable, especially the lengthy packages.yaml.

An example use case is: having config in this folder:

```
/path/to/programming/environment/{version}/{compilers,packages}.yaml
```

and have `module load spack-system-config` set the variable

```
SPACK_SYSTEM_CONFIG_PATH=/path/to/programming/environment/{version}
```

where the user no longer has to worry about what `{version}` they are
on.

**Continuous integration**

Finally, there is the use case of continuous integration, which may
clone an arbitrary Spack version, which optimally should not pick up
system or user config from the previous run (like may happen in
classical bare metal non-containerized filesystem side effect ridden
jenkins pipelines). In fact this is very similar to how spack itself
tries to avoid picking up system dependencies during builds...

**But environments solve this?**

- You could do `include`s in environment files to get similar behavior
  to the spack_system_config_path example, but environments require you
  to:
  1) require paths to individual config files, not directories.
  2) fail if the listed config file does not exist
- They allow you to override config scopes, but this is generally too
  rigurous, as it requires you to repeat the default config, in
  particular packages.yaml, and just defies the point of layered config.

installer: Support showing status information in terminal title (#16259)
Installing packages with a lot of dependencies does not have an easy way
of judging the current progress (apart from running `spack spec -I pkg`
in another terminal). This change allows Spack to update the terminal's
title with status information, including its current progress as well as
information about the current and total number of packages.

Make clingo the default solver (#25502)
Modifications:
- [x] Change `defaults/config.yaml`
- [x] Add a fix for bootstrapping patchelf from sources if `compilers.yaml` is empty
- [x] Make `SPACK_TEST_SOLVER=clingo` the default for unit-tests
- [x] Fix package failures in the e4s pipeline

Caveats:
1. CentOS 6 still uses the original concretizer as it can't connect to the buildcache due to issues with `ssl` (bootstrapping from sources requires a C++14 capable compiler)
1. I had to update the image tag for GitlabCI in e699f14.  
1. libtool v2.4.2 has been deprecated and other packages received some update

Bootstrap clingo from binaries (#22720)
* Bootstrap clingo from binaries

* Move information on clingo binaries to a JSON file

* Add support to bootstrap on Cray

Bootstrapping on Cray requires, at the moment, to
swap the platform when looking for binaries - due
to #22800.

* Add SHA256 verification for bootstrapped software

Use sha256 verification for binaries necessary to bootstrap
the concretizer and gpg for signature verification

* patchelf: use Spec._old_concretize() to bootstrap

As noted in #24450 we may happen to need the
concretizer when bootstrapping clingo. In that case
only the old concretizer is available.

* Add a schema for bootstrapping methods

Two fields have been added to bootstrap.yaml:
  "sources" which lists the methods available for
       bootstrapping software
  "trusted" which records if a source is trusted or not

A subcommand has been added to "spack bootstrap" to list
the sources currently available.

* Methods used for bootstrapping are configurable from bootstrap:sources

The function that tries to ensure a given Python module
is importable now tries bootstrapping methods in the same
order as they are defined in `bootstrap.yaml`

* Permit to trust/untrust bootstrapping methods

* Add binary tests for MacOS, Ubuntu

* Add documentation

* Add a note on bash

document config option "url_fetch_method" (#24638)
- Change config from the undocumented `use_curl: true/false` to `url_fetch_method: urllib/curl`.
- Documentation of `url_fetch_method` in `defaults/config.yaml`
- Default fetch option explicitly set to `urllib` for users who may not have curl on their system

To upgrade from `use_curl` to `url_fetch_method`, run `spack config update config`
