5f35bd7b67 cogl-object: Adds an internal _cogl_object_set_user_data
This adds an internal alternative to cogl_object_set_user_data that also
passes an instance pointer to destroy notify callbacks.

When setting private data on a CoglObject it's often desirable to know
the instance being destroyed when we are being notified to free the
private data due to the object being freed. The typical solution to this
is to track a pointer to the instance in the private data itself so it
can be identified but that usually requires an extra micro allocation
for the private data that could have been avoided if only the callback
were given an instance pointer.

The new internal _cogl_object_set_user_data passes the instance pointer
as a second argument which means it is ABI compatible for us to layer
the public version on top of this internal function.

0b2985ad66 cogl-object-private.h: Include cogl-debug.h
If COGL_OBJECT_DEBUG is defined then cogl-object-private.h will call
COGL_NOTE in the ref and unref macros. For this to work the debug
header needs to also be included or COGL_NOTE won't necessarily be
defined.

2c8bf00995 Don't define public cogl_is_* functions for internal types
This adds a COGL_OBJECT_INTERNAL_DEFINE macro and friends that are the
same as COGL_OBJECT_DEFINE except that they prefix the cogl_is_*
function with an underscore so that it doesn't get exported in the
shared library.

b25035ad2d cogl: Don't define the deprecated ref/unref accessors for new types
Previously COGL_OBJECT_DEFINE would always define deprecated
cogl_$type_{ref,unref} functions even if the type is new or if the
type is entirely internal. An application would still find it
difficult to use these because they wouldn't be in the headers, but it
still looks bad that they are exported from the shared library. This
patch changes it so that the deprecated ref counting functions are
defined using a separate macro and only the types that have these
functions in the headers call this macro.

51e4245ce1 cogl-object: cogl_is_XYZ prototype should take void *
This changes the cogl_is_XYZ function prototypes generated when using
the COGL_OBJECT_DEFINE macro to take a void * argument instead of a
CoglHandle argument.

0b3c45396b cogl-object-private.h: #include glib.h and cogl-types.h
cogl-object-private.h was only working in places that had already
included glib.h and cogl-types.h

2f286446af Add COGL_{OBJECT,HANDLE}_DEFINE_WITH_CODE
This macro is similar to COGL_HANDLE_DEFINE_WITH_CODE except that it
allows a snippet of code to be inserted into the _get_type()
function. This is similar to how G_DEFINE_TYPE_WITH_CODE
works. COGL_HANDLE_DEFINE is now just a wrapper around
COGL_HANDLE_DEFINE_WITH_CODE.

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.
