al_set_memory_interface - Allegro 5 API

       Override  the  memory  management  functions  with  implementations  of  al_malloc_with_context(3alleg5),
       al_free_with_context(3alleg5), al_realloc_with_context(3alleg5) and al_calloc_with_context(3alleg5).  The
       context arguments may be used for debugging.  The new functions should be thread safe.
