Rename CoglVertexArray to CoglAttributeBuffer This is part of a broader cleanup of some of the experimental Cogl API. One of the reasons for this particular rename is to switch away from using the term "Array" which implies a regular, indexable layout which isn't the case. We also want to have a strongly implied relationship between CoglAttributes and CoglAttributeBuffers.

Move all types/prototypes from cogl.h -> cogl[1]-context.h So we can get to the point where cogl.h is merely an aggregation of header includes for the 1.x api this moves all the function prototypes and type definitions into a cogl-context.h and a new cogl1-context.h. Ideally no code internally should ever need to include cogl.h as it just represents the public facing header for accessing the 1.x api which should only be used by Clutter.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

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.
