* frame-unwind.h: Update copyright.
(struct frame_data): Add opaque declaration.
(frame_sniffer_ftype): Declare.
(struct frame_unwind): Add "unwind_data" and "sniffer".
(frame_unwind_register_unwinder): Declare.
(frame_unwind_find_by_frame): Add parameter "this_cache".
* frame.c (get_frame_id, create_new_frame, legacy_get_prev_frame)
(legacy_get_prev_frame, legacy_get_prev_frame)
(get_frame_type): Pass the prologue_cache to
frame_unwind_find_by_frame.
* frame-unwind.c (struct frame_unwind_table_entry): Add field
"unwinder".
(frame_unwind_register_unwinder): New function.
(frame_unwind_find_by_frame): Handle an unwind sniffer.
