(longjmp_breakpoint_ops): New variable.
(update_breakpoints_after_exec, breakpoint_init_inferior): Delete also
bp_longjmp_call_dummy.
(bpstat_what, bptype_string, print_one_breakpoint_location)
(init_bp_location): Support bp_longjmp_call_dummy.
(set_longjmp_breakpoint): Use longjmp_breakpoint_ops. Comment why.
(set_longjmp_breakpoint_for_call_dummy)
(check_longjmp_breakpoint_for_call_dummy, longjmp_bkpt_dtor): New
functions.
(initialize_breakpoint_ops): Initialize longjmp_breakpoint_ops.
* breakpoint.h (enum bptype): New item bp_longjmp_call_dummy. Delete
FIXME comment and extend the other comment for bp_call_dummy.
(set_longjmp_breakpoint_for_call_dummy)
(check_longjmp_breakpoint_for_call_dummy): New declarations.
* dummy-frame.c: Include gdbthread.h.
(pop_dummy_frame_bpt): New function.
(pop_dummy_frame): Call pop_dummy_frame_bpt.

* gdbthread.h (struct thread_info): Extend initiating_frame comment.
* infcall.c (call_function_by_hand): New variable longjmp_b. Call
set_longjmp_breakpoint_for_call_dummy. Chain its breakpoints with BPT.
* infrun.c (handle_inferior_event) <BPSTAT_WHAT_CLEAR_LONGJMP_RESUME>:
Add case 4 comment. Call check_longjmp_breakpoint_for_call_dummy and
keep_going if IS_LONGJMP and there is no other reason to stop.
