Robert Bragg 09642a83b5 Removes all remaining use of CoglHandle
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.
