This PR adds a flag `--tag/-t` to `buildcache push`, which you can use like
```
$ spack mirror add my-oci-registry oci://example.com/hello/world
$ spack -e my_env buildcache push --base-image ubuntu:22.04 --tag my_custom_tag my-oci-registry
```
and lets users ship a full, installed environment as a minimal container image where each image layer is one Spack package, on top of a base image of choice. The image can then be used as
```
$ docker run -it --rm example.com/hello/world:my_custom_tag
```
Apart from environments, users can also pick arbitrary installed spec from their database, for instance:
```
$ spack buildcache push --base-image ubuntu:22.04 --tag some_specs my-oci-registry gcc@12 cmake
$ docker run -it --rm example.com/hello/world:some_specs
```
It has many advantages over `spack containerize`:
1. No external tools required (`docker`, `buildah`, ...)
2. Creates images from locally installed Spack packages (No need to rebuild inside `docker build`, where troubleshooting build failures is notoriously hard)
3. No need for multistage builds (Spack just tarballs existing installations of runtime deps)
4. Reduced storage size / composability: when pushing multiple environments with common specs, container image layers are shared.
5. Automatic build cache: later `spack install` of the env elsewhere speeds up since the containerized environment is a build cache
These packages were written before the "requires" directive,
and so they are conflicting with all compilers but Fujitsu
to express they _require_ `%fj`

* add trim function to `Spec` and `--ignore` option to 'spack diff'
Allows user to compare two specs while ignoring the sub-DAG of a particular dependency, e.g.
spack diff --ignore=mpi --ignore=zlib trilinos/abcdef trilinos/fedcba
to focus on differences closer to the root of the software stack
Sometimes env variables computed in `setup_run_environment` depend on tests
w.r.t. files in `spec.prefix`, but Spack temporarily projects `spec.prefix` to
the view.
This is problematic for two reasons:
1. Some packages iterate over `<prefix>/bin`: they expect only the current
package's executables, but find all linked in the view, leading to false
positives.
2. Some packages test for `os.path.islink(...)`, which is always true in a view
`gcc` is an example that does both.
This PR lets Spack compute the environment modifications using the original
prefix, and projects to the view afterwards
Currently, a virtual spec is composed of just a name and a version. When a virtual spec contains other components, such as variants, Spack won't emit warnings or errors but will silently drop them - which is unexpected by users.
This adds three new versions in the 31.* series. Release notes of 31.0.0 at https://github.com/acts-project/acts/releases/tag/v31.0.0. No changes to the CMakeLists.txt files that need addressing in the package recipe.
The only new feature I'm a bit concerned about is https://github.com/acts-project/acts/pull/2626, which replaces testing for C++20 concepts support by the feature-testing macro `__cpp_concepts`, which is also a C++20 feature. So technically we now should require `cxxstd=20` even though Acts itself still allows (and defaults to) 17. Judging by https://en.cppreference.com/w/cpp/compiler_support/20, the support for feature-testing macros was added very early by most compilers.
This PR changes the default behavior of `spack config get` and `spack config blame`
to print a flattened version of the entire spack configuration, including any active
environment, if the commands are invoked with no section arguments.
The new behavior is used in Gitlab CI to help debug CI configuration, but it can also
be useful when asking for more information in issues, or when simply debugging Spack.
