Removing CoglHandle has been an on going goal for quite a long time now and finally this patch removes the last remaining uses of the CoglHandle type and the cogl_handle_ apis. Since the big remaining users of CoglHandle were the cogl_program_ and cogl_shader_ apis which have replaced with the CoglSnippets api this patch removes both of these apis. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6ed3aaf4be21d605a1ed3176b3ea825933f85cf0) Since the original patch was done after removing deprecated API this back ported patch doesn't affect deprecated API and so actually this cherry-pick doesn't remove all remaining use of CoglHandle as it did for the master branch of Cogl.
