Meson has a very useful tool for combining a set of linked libraries and
compiler arguments (like an internal pkg-config):
`declare_dependency()`. Use this command to ensure that we can easily
reuse libapp* over multiple libraries, executables and tests.
That way, if we also add a new dependency later on in one of the libapp
libraries, this won't need to be added multiple times.
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.
