d02d40bf61 CoglObject: Adds a COGL_OBJECT macro for casting
This adds a convenience COGL_OBJECT macro for casting CoglObject
subclasses to (CoglObject *) pointers.

5af3ead3a2 CoglObject: Adds cogl_object_{get,set}_user_data
This provides a mechanism for associating private data with any
CoglObject. We expect Clutter will use this to associate weak materials
with normal materials.

5f8fadeb1c cogl: avoid ‘_cogl_xyz_handle_new’ defined but not used warnings
This patch makes it so that only the backwards compatibility
COGL_HANDLE_DEFINE macro defines a _cogl_xyz_handle_new function. The
new COGL_OBJECT_DEFINE macro only defines a _cogl_xyz_object_new
function.

7bcea1c64e Start eradicating the CoglHandle typedef
CoglHandle is a common source of complaints and confusion because people
expect a "handle" to be some form of integer type with some indirection
to lookup the corresponding objects as opposed to a direct pointer.

This patch starts by renaming CoglHandle to CoglObject * and creating
corresponding cogl_object_ APIs to replace the cogl_handle ones.

The next step though is to remove all use of CoglHandle in the Cogl APIs
and replace with strongly typed pointer types such as CoglMaterial * or
CoglTexture * etc also all occurrences of COGL_INVALID_HANDLE can just
use NULL instead.

After this we will consider switching to GTypeInstance internally so we
can have inheritance for our types and hopefully improve how we handle
bindings.

Note all these changes will be done in a way that maintains the API and
ABI.
