This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
Regression in commit a3d287c553.
When a given kwarg is not specified, we want to not generate it as a
simd variant. Since the default for buildtarget sources is `[]` it
resulted in building a static library with no sources, and a warning
stating that this was buggy and will eventually be removed.
Fix this by teaching buildtarget sources to allow None, and defaulting
to it specifically for the simd module. We can check this and then skip
processing entirely.
Fixes#12438
Thanks to `ModuleInfo`, all modules are just named `foo.py` instead of
`unstable_foo.py`, which simplifies the import method a bit. This also
allows for accurate FeatureNew/FeatureDeprecated use, as we know when
the module was added and if/when it was stabilized.
