* frame.c (get_frame_id): Default to outer_frame_id if the this_id
method does not supply an ID. Assert that the result is not
null_frame_id.
(outer_frame_id): New.
(frame_id_p): Accept outer_frame_id.
(frame_id_eq): Allow outer_frame_id to be equal to itself.
(frame_find_by_id): Revert previous local workarounds.
(get_prev_frame_1): Adjust end-of-stack check to test outer_frame_id.
* frame.h (null_frame_id, frame_id_p): Update comments.
(outer_frame_id): Declare.
* infrun.c (handle_inferior_event): Do not treat all steps from the
outermost frame as subroutine calls.
* libunwind-frame.c (libunwind_frame_this_id): Do not clear THIS_ID.
* hppa-tdep.c (hppa_stub_frame_this_id): Likewise.
* ia64-tdep.c (ia64_frame_this_id): Likewise.
(ia64_libunwind_frame_this_id, ia64_libunwind_sigtramp_frame_this_id):
Use outer_frame_id instead of null_frame_id.
* amd64obsd-tdep.c (amd64obsd_trapframe_cache): Use outer_frame_id.
* i386obsd-tdep.c (i386obsd_trapframe_cache): Likewise.
* inline-frame.c (inline_frame_this_id): Refuse outer_frame_id.
* thread.c (restore_selected_frame): Update comment and remove
frame_id_p check.
gdb/doc/
* gdbint.texinfo (Unwinding the Frame ID): Reference outer_frame_id.
