build: Allow to build cogl without an external glib dependency

This commit pushes --disable-glib to the extreme of embedding the par of
glib cogl depends on in tree to be able to generate a DSO that does not
depend on an external glib.

To do so, it:
  - keeps a lot of glib's configure.ac in as-glibconfig.m4
  - pulls the code cogl depends on and the necessary dependencies
