Sometimes it's just too much effort to subclass GstBuffer, just to specify that
the free function should be free() instead of g_free().

So I would suggest that buffer instances could include free functions in
themselves. Patch attached.

The patch does not expand the size of GstBuffer, even if the reserved members
were reserved in some future version of GStreamer, as we could simply drop the
malloc_data field and keep the free_func function pointer.
