(execute_unwinders): New function. * python/lib/gdb/command/unwinders.py: New file. * python/lib/gdb/unwinder.py: New file. * python/py-objfile.c (objfile_object): Add frame_unwinders field. (objfpy_dealloc): Decrement frame_unwinders reference count. (objfpy_initialize): Create frame_unwinders list. (objfpy_get_frame_unwinders): New function. (objfpy_set_frame_unwinders): Ditto. (objfile_getset): Add frame_unwinders attribute to Objfile. * python/py-progspace.c (pspace_object): Add frame_unwinders field. (pspy_dealloc): Decrement frame_unwinders reference count.
