If you have an environment like
```
$ cat spack.yaml
spack:
specs: [openmpi@4.1.0+cuda]
```
this PR provides a new command `spack change` that you can use to adjust environment specs from the command line:
```
$ spack change openmpi~cuda
$ cat spack.yaml
spack:
specs: [openmpi@4.1.0~cuda]
```
in other words, this allows you to tweak the details of environment specs from the command line.
Notes:
* This is only allowed for environments that do not define matrices
* This is possible but not anticipated to be needed immediately
* If this were done, it should probably only be done for "named"/not-anonymous specs (i.e. we can change `openmpi+cuda` but not spec like `+cuda` or `@4.0.1~cuda`)
The building of tests is optional [as of 2.42.9](801eef111d). This applies this option in the build.
The reason the option was added was to deal with test build failures in sandboxed environments and with certain glibc versions (caused by glib gresources). For example, with the latest version glibc and in the latest version of docker these tests [cannot be built](https://github.com/moby/moby/issues/43595).

i.e use -DBUILTINS_CMAKE_ARGS=-DCOMPILER_RT_ENABLE_IOS=OFF. But this needs switching "compiler-rt" from "projects" to "runtimes".

fixes#31484
Before this change if anything was matching an external
condition, it was considered "external" and thus something
to be "built".
This was happening in particular to external packages
that were re-read from the DB, which then couldn't be
reused, causing the problems shown in #31484.
This PR fixes the issue by excluding specs with a
"hash" from being considered "external"
* Test that users have a way to select a virtual
This ought to be solved by extending the "require"
attribute to virtual packages, so that one can:
```yaml
mpi:
require: 'multi-provider-mpi'
```
* Prevent conflicts to be enforced on specs that can be reused.
* Rename the "external_only" fact to "buildable_false", to better reflect its origin
* py-breathe: add new version and improve version constraints
* py-breathe: everyone loves versions
```
py-breathe, py-breathe in the air

* Preliminary support for include URLs in spack.yaml (environment) files
This commit adds support in environments for external configuration files obtained from a URL with a preference for grabbing raw text from GitHub and gitlab for efficient downloads of the relevant files. The URL can also be a link to a directory that contains multiple configuration files.
Remote configuration files are retrieved and cached for the environment. Configuration files with the same name will not be overwritten once cached.
Extend the semantics of package requirements to
allow using them also under a virtual package
attribute in packages.yaml
These requirements are enforced whenever that
virtual spec is present in the DAG.
