The cogl.h header is meant to be the public header for including the 1.x api used by Clutter so we should stop using that as a convenient way to include all likely prototypes and typedefs. Actually we already do a good job of listing the specific headers we depend on in each of the .c files we have so mostly this patch just strip out the redundant includes for cogl.h with a few fixups where that broke the build.
