This PR introduces a new build cache layout and package format, with improvements for
both efficiency and security.
## Old Format
Currently a binary package consists of a `spec.json` file at the root and a `.spack` file,
which is a `tar` archive containing a copy of the `spec.json` format, possibly a detached
signature (`.asc`) file, and a tar-gzip compressed archive containing the install tree.
```
build_cache/
# metadata (for indexing)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
<arch>/
<compiler>/
<name>-<ver>/
# tar archive
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
# tar archive contents:
# metadata (contains sha256 of internal .tar.gz)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
# signature
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.asc
# tar.gz-compressed prefix
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.tar.gz
```
After this change, the nesting has been removed so that the `.spack` file is the
compressed archive of the install tree. Now signed binary packages, will take the
form of a clearsigned `spec.json` file (a `spec.json.sig`) at the root, while unsigned
binary packages will contain a `spec.json` at the root.
## New Format
```
build_cache/
# metadata (for indexing, contains sha256 of .spack file)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
# clearsigned spec.json metadata
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.sig
<arch>/
<compiler>/
<name>-<ver>/
# tar.gz-compressed prefix (may support more compression formats later)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
```
## Benefits
The major benefit of this change is that the signatures on binary packages can be
verified without:
1. Having to download the tarball, or
2. having to extract an unknown tarball.
(1) is an improvement in efficiency; (2) is a security fix: we now ensure that we trust the
binary before we try to run it through `tar`, which avoids potential attacks.
## Backward compatibility
Also after this change, spack should still be able to handle the previous buildcache
structure and binary mirrors with mixed layouts.
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
* Allow Kokkos with OpenMPTarget backend
* Restrict SYCL and OpenMPTarget to C++17 or higher
* Improve C++ standard check for SYCL and OpenMPTarget
* Fix indentation
Currently, environments can either be concretized fully together or fully separately. This works well for users who create environments for interoperable software and can use `concretizer:unify:true`. It does not allow environments with conflicting software to be concretized for maximal interoperability.
The primary use-case for this is facilities providing system software. Facilities provide multiple MPI implementations, but all software built against a given MPI ought to be interoperable.
This PR adds a concretization option `concretizer:unify:when_possible`. When this option is used, Spack will concretize specs in the environment separately, but will optimize for minimal differences in overlapping packages.
* Add a level of indirection to root specs
This commit introduce the "literal" atom, which comes with
a few different "arities". The unary "literal" contains an
integer that id the ID of a spec literal. Other "literals"
contain information on the requests made by literal ID. For
instance zlib@1.2.11 generates the following facts:
literal(0,"root","zlib").
literal(0,"node","zlib").
literal(0,"node_version_satisfies","zlib","1.2.11").
This should help with solving large environments "together
where possible" since later literals can be now solved
together in batches.
* Add a mechanism to relax the number of literals being solved
* Modify spack solve to display the new criteria
Since the new criteria is above all the build criteria,
we need to modify the way we display the output.

to this branch by the co-author of the commit.

* Inject reusable specs into the solve
Instead of coupling the PyclingoDriver() object with
spack.config, inject the concrete specs that can be
reused.
A method level function takes care of reading from
the store and the buildcache.
* spack solve: show output of multi-rounds
* add tests for best-effort coconcretization
* Enforce having at least a literal being solved

Previously the regex was only checking for presence of quotes as a beginning
or end character and not a matching set. This erroneously identified the
following *single* argument as being quoted:
source bashenvfile &> /dev/null && python3 -c "import os, json; print(json.dumps(dict(os.environ)))"

Add a config option to strip `-Werror*` or `-Werror=*` from compile lines everywhere.
```yaml
config:
keep_werror: false
```
By default, we strip all `-Werror` arguments out of compile lines, to avoid unwanted
failures when upgrading compilers. You can re-enable `-Werror` in your builds if
you really want to, with either:
```yaml
config:
keep_werror: all
```
or to keep *just* specific `-Werror=XXX` args:
```yaml
config:
keep_werror: specific
```
This should make swapping in newer versions of compilers much smoother when
maintainers have decided to enable `-Werror` by default.
Parse error information is kept for specs, but it doesn't seem like we propagate it
to the user when we encounter an error. This fixes that.
e.g., for this error in a package:
```python
depends_on("python@:3.8", when="0.900:")
```
Before, with no context and no clue that it's even from a particular spec:
```
==> Error: Unexpected token: ':'
```
With this PR:
```
==> Error: Unexpected token: ':'
Encountered when parsing spec:
0.900:
^
```

Notes:
- Updated mpark-variant to remove conflict that no longer exists in Amazon Linux
- Which command on Amazon Linux prefixes on all results when padded_length is too high. In this case, padded_length<=503 works as expected. Chose conservative length of 384.

Add a `build_type` variant, which allows building optimized compilers,
as well as target libraries (libstdc++ and friends).
The default is `build_type=RelWithDebInfo`, which corresponds to GCC's
default of -O2 -g.
When building with `+bootstrap %gcc`, also add Spack's arch specific
flags using the common denominator between host and new GCC.
It is done by creating a config/spack.mk file in def patch, that looks
as follows:
```
BOOT_CFLAGS := $(filter-out -O% -g%, $(BOOT_CFLAGS)) -O2 -g -march=znver2 -mtune=znver2
CFLAGS_FOR_TARGET := $(filter-out -O% -g%, $(CFLAGS_FOR_TARGET)) -O2 -g -march=znver2 -mtune=znver2
CXXFLAGS_FOR_TARGET := $(filter-out -O% -g%, $(CXXFLAGS_FOR_TARGET)) -O2 -g -march=znver2 -mtune=znver2
```
The oneapi and dpcpp compilers are essentially the same except for which
binary is used foc CXX. Spack will detect them as "mixed toolchain" and
not inject compiler optimization flags. This will be needed once
archspec has entries for the oneapi and dpcpp compilers. This PR detects
when dpcpp and oneapi are in the toolchains list and explicitly sets
`is_mixed_toolchain` to `False`.
