Since we've had several developers from admirable projects say they would like to use Cogl but would really prefer not to pull in gobject,gmodule and glib as extra dependencies we are investigating if we can get to the point where glib is only an optional dependency. Actually we feel like we only make minimal use of glib anyway, so it may well be quite straightforward to achieve this. This adds a --disable-glib configure option that can be used to disable features that depend on glib. Actually --disable-glib doesn't strictly disable glib at this point because it's more helpful if cogl continues to build as we make incremental progress towards this. The first use of glib that this patch tackles is the use of g_return_val_if_fail and g_return_if_fail which have been replaced with equivalent _COGL_RETURN_VAL_IF_FAIL and _COGL_RETURN_IF_FAIL macros.
