3cd006bb2b Fix to accept a cairo_pattern_t rather than a cairo_surface_t as the primary argument. 
Track change in _cairo_pattern_release_surface and also pass the appropriate pattern for each acquired surface. The previous backend mismatch was causing memory leaks.

dda555de99 Remove destroy notifier. This simplifies the implementation a bit, and no anticipated use of cairo_hash_table_t in cairo needs the destroy notifier. Most uses will be hash-backed object create/destroy functions. 
(_cairo_hash_table_destroy): Document that it is now a fatal error to call _cairo_hash_table_destroy on a non-empty hash table.
(_cairo_hash_table_insert): Document that it is now a fatal error to insert an entry with a key that matches an existing entry.
(_cairo_hash_table_random_entry): Add predicate function so that the user can select a random entry satisying the given predicate.
(_cairo_hash_table_remove): Change return type to void since failure is really not possible here.
