[PATCH libxkbcommon 00/11] Fix all compiler warnings

[Ran Benita]

With this series applied libxkbcommon is compiled without warnings on
gcc and clang, using the default CWARNFLAGS.
I had also ran clang-analyzer and fixed all the warnings there.
The patches should be independent so if any of them are problematic
they can be dropped.

Thanks,
Ran
