Re: [PATCH 2/2] meson: Declare GLIB_VERSION_* macros at configure

So far we have three places where glib version is recorded: meson.build and then in config.h. The latter is so well hidden that it's easy to miss when bumping minimal glib version in the former. With a bit of python^Wmeson string magic GLIB_VERSION_MIN_REQUIRED and GLIB_VERSION_MAX_ALLOWED macros can be defined to match glib_version from meson.build.
