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.

This should make it faster to do type checks because it does not need to call a function every time it wants to get the type number. Reviewed-by: Robert Bragg <robert@linux.intel.com>

One exception to this is the bool type, for which the commit introduces a new type CoglBool. Let's just get rid of this type in favor of having consistency with the GLib types. Note by the way that neither CoglBool nor gboolean (which has a size of `int`) are completely compatible with bool (size `char`). https://gitlab.gnome.org/GNOME/mutter/merge_requests/321

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.

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.

cogl: Mark exported cogl symbols using COGL_EXPORT Just like libmutter-clutter, and libmutter, mark exported symbols with an COGL_EXPORT macro. This removes the .map and .map.in files previously used, containing a list of semi private symbols. This symbol was out of date, i.e. pointed to non-existing symbols, and was also replaced with COGL_EXPORT macros. unit_test_* symbols are exported by the help of the unit test defining macro. test_* symbols are no longer supported as it proved unnecessary. https://gitlab.gnome.org/GNOME/mutter/merge_requests/1059

object: Add a virtual pointer for the unref function The virtual function gets called in cogl_object_unref. Any definition of a CoglObject type can replace the default unref function by using COGL_OBJECT_DEFINE_WITH_CODE to directly manipulate the CoglObjectClass struct. The generated object constructors set the pointer to the default implementation. The default implementation is exported in the private header so that any overriding implementations can chain up to it. Reviewed-by: Robert Bragg <robert@linux.intel.com>
