This commit adds several meson.build, which successfully build and
install Lix executables, libraries, and headers. Meson does not yet
build docs, Perl bindings, or run tests, which will be added in
following commits. As such, this commit does not remove the existing
build system, or make it the default, and also as such, this commit has
several FIXMEs and TODOs as notes for what should be done before the
existing autoconf + make buildsystem can be removed and Meson made the
default. This commit does not modify any source files.
A Meson-enabled build is also added as a Hydra job, and to
`nix flake check`.

# because we need to specifically *join* DESTDIR and includedir with a slash, and *not*
|
|
# have a slash if DESTDIR isn't set at all, since $includedir could be a relative directory.
|
|
# Finally, DESTDIR is only available to us as an environment variable in these install scripts,
|
|
# not in Meson logic.
|

# Therefore, our best option is to have Meson pass this script the configured includedir,
|
|
# and perform this dance with it and $DESTDIR.
