* add new package libsixel
* reorder to group variants and dependencies together
* Switch to using source from fork
The original developer of libsixel, Hayaki Saito (@saitoha), disappeared
in early 2020 and has not updated the repository or been seen since.
However, a fork of the project has been created at libsixel/libsixel,
and that fork has been getting much more regular updates. In this commit
I switch the package to using the better-maintained, now apparently
canonical fork of the project.
That project switched the build system from autotools to Meson, so much
of the build arguments code needed to be rewritten. The newest official
release also contained an error in meson.build which would break on
newer versions of Meson. That error only applied to the libjpeg and
libpng variants, though, so I switched the default to use libgd which
has broader format support anyway.
* blacken
* broke description into multiple lines
* allow libjpeg, etc to be loaded automatically
* apply patch to all compilers as per spack/issues/42007
* [@spackbot] updating style on behalf of Chrismarsh
* Resolve flake8 style issue from spackbot
* fix flake8 trailing whitespace

These 7 hooks were not used.
- Six of them related to install phases were unused after `spack`
`monitor` was removed, and the code seems to have bit rotten as there
were reports they were not (always?) triggered when they should.
- The post environment one was made redundant after spack install for
environment started following the common code path for generating
module files in #42147.
It should not be a breaking change to remove, since users cannot define
hooks in extensions, they would have to fork Spack.
If we ever _were_ to make those hooks extendable outside of core Spack,
it would also be better to start with fewer rather than more, cause
everything you expose gets relied upon...
Removing those also allows us to rethink what hooks we really need, and
in particular it seems like we need a hook that runs post install also when
the spec is inserted into the database.
The lack of a rule to avoid enforcing requirements on multi-valued variants, when the condition activating the environment was not met, resulted in multiple optimal solutions. The fix is to prevent imposing a requirement if the when= rule activating it is not met.
The section was highly outdated as it referred to old defaults, and
failed to mention `hide_implicits: true`.
This commit restructures it, moves some deeply nested sections a level
up, and promotes `hide_implicits: true` + `autoload: direct` before
talking about `exclude`.
It is useful to enable/disable stacks in order to handle turning
specific stacks on/off based on runner availability, stack stability,
testing requirements, etc.
The disabled stack list takes precedence over the enable stack list. The
assumption is that stacks that are disabled are so due to some
functionality missing or broken for that stack.
The enable stack list implicitly disables all stacks not listed in the
enable list.
* Registry queries can fail due to simultaneous access from other
processes. Wrap some of these accesses and retry when this may
be the cause (the generated exceptions don't allow pinpointing
this as the reason, but we add logic to identify cases which
are definitely unrecoverable, and retry if it is not one of
these).
* Add make recursion optioal for most registry search functions;
disable recursive search in case where it was originally always
recursive.
