Async mode fixes.
* Makefile.in (infcmd.o, inf-loop.o): Update dependencies. * breakpoint.c (bpstat_do_actions): In async mode, don't jump to top expecting stop_bpstat to be already updated. * event-loop.c (start_event_loop): Call async_enable_stdin on exception. * event-top.c (async_enable_stdin): Do nothing if sync_execution is not set. (command_handler): Do not setup continuation here. (command_line_handler_continuation): Move to... * top.c (command_line_handler_continuation): ... here. (execute_command): In async mode, register continuation. Don't check frame's language in running in async mode. * exceptions.c (throw_exception): Don't do exec_error_cleanups. * inf-loop.c (complete_execution): Inline into... (inferior_event_handler): ... here. Clear target_executing before doing any cleanups. Don't try to show prompt if the target was resumed. * infcmd.c (signal_command): Add support for async mode. (finish_command): Only add continuation if the target was successfully resumed. * remote.c (init_async_opts): Register to_get_thread_local_address handler. * mi/mi-interp.c (mi_cmd_interpreter_exec): Don't mess with sync_execution. * tui/tui-interp.c (tui_command_loop): Call async_enable_stdin on exception.
