gdb: add debug prints in event loop
Add debug printouts about event loop-related events:
- When a file descriptor handler gets invoked
- When an async event/signal handler gets invoked
gdb/ChangeLog:
* async-event.c (invoke_async_signal_handlers): Add debug
print.
(check_async_event_handlers): Likewise.
* event-top.c (show_debug_event_loop): New function.
(_initialize_event_top): Register "set debug event-loop"
setting.
gdbserver/ChangeLog:
* server.cc (handle_monitor_command): Handle "set
debug-event-loop".
(captured_main): Handle "--debug-event-loop".
(monitor_show_help): Mention new setting.
(gdbserver_usage): Mention new flag.
gdbsupport/ChangeLog:
* event-loop.h (debug_event_loop): New variable declaration.
(event_loop_debug_printf_1): New function declaration.
(event_loop_debug_printf): New macro.
* event-loop.cc (debug_event_loop): New variable.
(handle_file_event): Add debug print.
(event_loop_debug_printf_1): New function.
