Now that we bumped our meson requirement, meson is complaining about
several features now deprecated even in the minimum required meson
version:
s/meson.source_root/meson.project_source_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.source_root. use meson.project_source_root() or meson.global_source_root() instead.
s/meson.build_root/meson.project_build_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.build_root. use meson.project_build_root() or meson.global_build_root() instead.
Fixing using path() on xdg_email and python ExternalProgram variables:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
s/get_pkgconfig_variable *(\([^)]*\))/get_variable(pkgconfig: \1)/ to
fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': dependency.get_pkgconfig_variable. use dependency.get_variable(pkgconfig : ...) instead
Our meson build system was not properly building the enums.c file,
because they are versionned.
I did a similar trick as what I did for the pdbgen, which is that I used
a wrapper script around the existing perl script, which sets proper
options and generate a stamp file in the end (which is considered by
meson as the actual custom target, not the C file since it is generated
in the source dir).
The most important part is that the stamp file is a generated header
source (not just a random text file) which is **included** by the
generated C file. This is what will force meson to regenerate the C file
if the header is updated, **then** build using this new version, not use
an outdated versionned version (which would make for hard to diagnose
bugs), through the indirection of the intermediate stamp header.
See #4201.

More of the files were wrong, or at least not absolutely identical to
the files generated by the autotools. I am not doing any code change
other than trying to make both build systems produce identical files
(except for slight differences on 2 files not worth the effort) even
though maybe some things can be improved (especially on the include
list). Maybe to be improved later.
Also fixing 2 of the previously autotools-generated files because of
space typos which should have been committed earlier.
Finally it is to be noted that there is no logics to copy the generated
files back to the source directory in the meson rules. I am not sure
anyway this is really worth it and maybe we should just stop tracking
these generated files eventually.
