* Update Nalu-Wind to remove SuperLU from Trilinos requirement. Also simplify Nalu-Wind package.
* Leave boost option in nalu-wind.
* Add git branches into TPL requirements. Update OpenFAST for change to main branch.
Currently, environment views blink out of existence during the view regeneration, and are slowly built back up to their new and improved state. This is not good if other processes attempt to access the view -- they can see it in an inconsistent state.
This PR fixes makes environment view updates atomic. This requires a level of indirection (via symlink, similar to nix or guix) from the view root to the underlying implementation on the filesystem.
Now, an environment view at `/path/to/foo` is a symlink to `/path/to/._foo/<hash>`, where `<hash>` is a hash of the contents of the view. We construct the view in its content-keyed hash directory, create a new symlink to this directory, and atomically replace the symlink with one to the new view.
This PR has a couple of other benefits:
* It future-proofs environment views so that we can implement rollback.
* It ensures that we don't leave users in an inconsistent state if building a new view fails for some reason.
For background:
* there is no atomic operation in posix that allows for a non-empty directory to be replaced.
* There is an atomic `renameat2` in the linux kernel starting in version 3.15, but many filesystems don't support the system call, including NFS3 and NFS4, which makes it a poor implementation choice for an HPC tool, so we use the symlink approach that others tools like nix and guix have used successfully.
* Added the option to use high performance linkers: gold and lld, for
LBANN. Including them as build flags causes unnecessary propagation
to all dependent packages, reducing package reuse.

The ASP-based solver now accounts for the presence
in the DAG of deprecated versions and tries to minimize
their number at highest priority.
* gobject-introspection: fix for Python 3.9.
* Fixes the too long line formatting issue.

Variants explicitly set in an abstract root spec are considered
as defaults for the package they refer to, and they override
what is in packages.yaml and in package.py. This is relevant
only for multi-valued variants, where a constraint may extend
an already default value.
* Fixes to flex
- Prefer the version that doesn't need all the patches and extra build
tools
- Make dependency on gettext optional under the nls variant (off by
default)
- Drop the dependency on help2man if we don't have to regenerate the man
pages (when no patches are necessary)
* Bring back gettext dep as it is used during autoconf
The code for guessing cpu archtype based on craype modules names got confused,
at least on LLNL RZ prototype systems. In particular a (L) or (D) at the end of a craype-x86-xxx or other
cpu architecture module was geting the logic confused.
With this patch, any white space + remaining characters in the moduel name are removed.

There have been a lot of questions and some confusion recently surrounding Spack installation test capabilities so this PR is intended to clean up and refine the documentation for "Checking an installation".
It aims to better distinguish between checks that are performed during an installation (i.e., build-time tests) and those that can be done days and weeks after the software has been installed (i.e., install (or smoke) tests).
