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`

pbs: new virtual package (#24568)
* pbs: new virtual package

Some of our clusters have an older installation of
libtorque and tm.h that are *not* from OpenPBS. Using the current
openpbs dependency for openmpi causes concretization errors due to
restrictions on older python and hwloc requirements that don't apply,
even with an external non-buildable installation.
The new 'torque' bundle package allows users to point to that external
installation without problems.

add irep and lua-lang virtual dependency (#22492)
This adds a package for `irep`, a tool for reading `lua` input decks from 
Fortran, C, and C++.

`irep` can be built with either `lua` or `luajit`.  To address this, we also add
a virtual package for lua called `lua-lang`.  `luajit` isn't, by default, a drop-in
replacement for `lua`, but we add a `+lualinks` variant to it that adds symlinks
that make it behave like `lua@5.1`.  With this variant enabled, it provides the
`lua-lang` virtual.  `lua` always provides `lua-lang`.

- [x] add `irep` package
- [x] add `+lualinks` variant to `lua-luajit`
- [x] create `lua-lang` virtual, provided by `lua` and `luajit+lualinks`

Separable module configuration -- without the bugs this time (#23703)
Currently, module configurations are inconsistent because modulefiles are generated with the configs for the active environment, but are shared among all environments (and spack outside any environment).

This PR fixes that by allowing Spack environments (or other spack config scopes) to define additional sets of modules to generate. Each set of modules can enable either lmod or tcl modules, and contains all of the previously available module configuration. The user defines the name of each module set -- the set configured in Spack by default is named "default", and is the one returned by module manipulation commands in the absence of user intervention.

As part of this change, the module roots configuration moved from the config section to inside each module configuration.

Additionally, it adds a feature that the modulefiles for an environment can be configured to be relative to an environment view rather than the underlying prefix. This will not be enabled by default, as it should only be enabled within an environment and for non-default views constructed with separate projections per-spec.

Use AWS CloudFront for source mirror (#23978)
Spack's source mirror was previously in a plain old S3 bucket. That will still
work, but we can do better. This switches to AWS's CloudFront CDN for hosting
the mirror.

CloudFront is 16x faster (or more) than the old bucket.

Make -j flag less exceptional (#22360)
* Make -j flag less exceptional

The -j flag in spack behaves differently from make, ctest, ninja, etc,
because it caps the number of jobs to an arbitrary number 16.
Spack will behave like other tools if `spack install` uses a reasonable
default, and `spack install -j <num>` *overrides* that default.

This will be particularly useful for Spack usage outside of a traditional
HPC context and for HPC centers that encourage users to compile on
login nodes with many cores instead of on compute nodes, which has
become increasingly common as individual nodes have more cores.

This maintains the existing default value of min(num_cpus, 16). However, 
as it is right now, Spack does a poor job at determining the number of 
cpus on linux, since it doesn't take cgroups into account. This is
particularly problematic when using distributed builds with slurm. This PR
also introduces `spack.util.cpus.cpus_available()` to consolidate
knowledge on determining the number of available cores, and improves
core detection for linux. This should also improve core detection for Docker/
Kubernetes, which also use cgroups.

Drop compiler variables from spack load (#21699)
Drops:

* C_INCLUDE_PATH
* CPLUS_INCLUDE_PATH
* LIBRARY_PATH
* INCLUDE

We already decided to use C_INCLUDE_PATH, CPLUS_INCLUDE_PATH, INCLUDE over CPATH here:

https://github.com/spack/spack/pull/14749

However, none of these flags apply to Fortran on Linux. So for consistency it seems better to make the user use -I and -L flags by hand or through pkgconfig.

Introduce virtual provider uuid (#18322)
libuuid is currently contained in util-linux, libuuid and uuid. This
change introduces a new virtual provider `uuid` and renames the existing
`uuid` package to `ossp-uuid`.

util-linux's libuuid is provided in the form of a separate package
util-linux-uuid to make sure that packages depending on uuid and
util-linux can use a separate uuid implementation, which the concretizer
does not allow if libuuid is contained in util-linux.

spack test (#15702)
Users can add test() methods to their packages to run smoke tests on
installations with the new `spack test` command (the old `spack test` is
now `spack unit-test`). spack test is environment-aware, so you can
`spack install` an environment and then run `spack test run` to run smoke
tests on all of its packages. Historical test logs can be perused with
`spack test results`. Generic smoke tests for MPI implementations, C,
C++, and Fortran compilers as well as specific smoke tests for 18
packages.

Inside the test method, individual tests can be run separately (and
continue to run best-effort after a test failure) using the `run_test`
method. The `run_test` method encapsulates finding test executables,
running and checking return codes, checking output, and error handling.

This handles the following trickier aspects of testing with direct
support in Spack's package API:

- [x] Caching source or intermediate build files at build time for
      use at test time.
- [x] Test dependencies,
- [x] packages that require a compiler for testing (such as library only
      packages).

See the packaging guide for more details on using Spack testing support.
Included is support for package.py files for virtual packages. This does
not change the Spack interface, but is a major change in internals.

move sbang to unpadded install tree root (#19640)
Since #11598 sbang has been installed within the install_tree. This doesn’t play
nicely with install_tree padding, since sbang can’t do its job if it is installed in a
long path (this is the whole point of sbang).

This PR changes the padding specification.  Instead of $padding inside paths,
we now have a separate `padding:` field in the `install_tree` configuration.

Previously, the `install_tree` looked like this:

```
    /path/to/opt/spack_padding_padding_padding_padding_padding/
        bin/
            sbang
        .spack-db/
            ...
        linux-rhel7-x86_64/
            ...
```

```
This PR updates things to look like this:

    /path/to/opt/
        bin/
            sbang
        spack_padding_padding_padding_padding_padding/
            .spack-db/
                ...
            linux-rhel7-x86_64/
                ...

So padding is added at the start of all install prefixes *within* the unpadded
root.  The database and all installations still go under the padded root.

This ensures that `sbang` is in the shorted possible path while also allowing
us to make long paths for relocatable binaries.

193e8333fa Update packages.yaml format and support configuration updates
The YAML config for paths and modules of external packages has
changed: the new format allows a single spec to load multiple
modules. Spack will automatically convert from the old format
when reading the configs (the updates do not add new essential
properties, so this change in Spack is backwards-compatible).

With this update, Spack cannot modify existing configs/environments
without updating them (e.g. “spack config add” will fail if the
configuration is in a format that predates this PR). The user is
prompted to do this explicitly and commands are provided. All
config scopes can be updated at once. Each environment must be
updated one at a time.

1f5ef5c876 darwin: cut DYLD_LIBRARY_PATH from default modules
This commit removes the DYLD_LIBRARY_PATH variable from the default

environment variable is that paths in this environment variable take
precedence over the default locations of libraries (usually the
install path of the library), which can lead to linking errors in some
circumstances. For example, executables intended to link with Apple's
system BLAS and LAPACK will instead link to a spack-installed
implementation (e.g., OpenBLAS), causing runtime errors.

These errors are resolved by instead relying on paths set in
DYLD_FALLBACK_LIBRARY_PATH, which is lower in precedence than default
locations of libraries.

multiprocessing: allow Spack to run uninterrupted in background (#14682)
Spack currently cannot run as a background process uninterrupted because some of the logging functions used in the install method (especially to create the dynamic verbosity toggle with the v key) cause the OS to issue a SIGTTOU to Spack when it's backgrounded.

This PR puts the necessary gatekeeping in place so that Spack doesn't do anything that will cause a signal to stop the process when operating as a background process.

Module files won't use CPATH by default, but language specific vars (#14749)
fixes #11555

Every path in CPATH is equivalent to a -I path to the compiler,
while every path in *_INCLUDE_PATH is equivalent to -isystem.
The latter avoids the noise due to warnings coming from 3rd party
libraries that a project depends on.

Added INCLUDE env variable (Intel Fortran, .mod files)

7325c20794 config: Add a new option connect_timeout
connect_timeout can be used to increase the time Spack waits for the
server to answer. This can be used to work around slow connections or
servers.

Distributed builds (#13100)
Fixes #9394
Closes #13217.

## Background
Spack provides the ability to enable/disable parallel builds through two options: package `parallel` and configuration `build_jobs`.  This PR changes the algorithm to allow multiple, simultaneous processes to coordinate the installation of the same spec (and specs with overlapping dependencies.).

The `parallel` (boolean) property sets the default for its package though the value can be overridden in the `install` method.

Spack's current parallel builds are limited to build tools supporting `jobs` arguments (e.g., `Makefiles`).  The number of jobs actually used is calculated as`min(config:build_jobs, # cores, 16)`, which can be overridden in the package or on the command line (i.e., `spack install -j <# jobs>`).

This PR adds support for distributed (single- and multi-node) parallel builds.  The goals of this work include improving the efficiency of installing packages with many dependencies and reducing the repetition associated with concurrent installations of (dependency) packages.

## Approach
### File System Locks
Coordination between concurrent installs of overlapping packages to a Spack instance is accomplished through bottom-up dependency DAG processing and file system locks.  The runs can be a combination of interactive and batch processes affecting the same file system.  Exclusive prefix locks are required to install a package while shared prefix locks are required to check if the package is installed.

Failures are communicated through a separate exclusive prefix failure lock, for concurrent processes, combined with a persistent store, for separate, related build processes.  The resulting file contains the failing spec to facilitate manual debugging.

### Priority Queue
Management of dependency builds changed from reliance on recursion to use of a priority queue where the priority of a spec is based on the number of its remaining uninstalled dependencies.  

Using a queue required a change to dependency build exception handling with the most visible issue being that the `install` method *must* install something in the prefix.  Consequently, packages can no longer get away with an install method consisting of `pass`, for example.

## Caveats
- This still only parallelizes a single-rooted build.  Multi-rooted installs (e.g., for environments) are TBD in a future PR.

Tasks:
- [x] Adjust package lock timeout to correspond to value used in the demo
- [x] Adjust database lock timeout to reduce contention on startup of concurrent
    `spack install <spec>` calls
- [x] Replace (test) package's `install: pass` methods with file creation since post-install 
    `sanity_check_prefix` will otherwise error out with `Install failed .. Nothing was installed!`
- [x] Resolve remaining existing test failures
- [x] Respond to alalazo's initial feedback
- [x] Remove `bin/demo-locks.py`
- [x] Add new tests to address new coverage issues
- [x] Replace built-in package's `def install(..): pass` to "install" something
    (i.e., only `apple-libunwind`)
- [x] Increase code coverage

c587c76537 Config option to allow gpg warning suppression (#13743)
Add a configuration option to suppress gpg warnings during binary
package verification. This only suppresses warnings: a gpg failure
will still fail the install. This allows users who have already
explicitly trusted the gpg key they are using to avoid seeing
repeated warnings that it is self-signed.
