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 Reviewed-by: Robert Bragg <robert@linux.intel.com>
