Use target_terminal_ours_for_output in MI

The MI code only does output, so leave raw/cooked mode alone, as well
as the SIGINT handler.  Restore terminal settings after output, while
at it.  Also, a couple events missed calling target_terminal_ours
before output, even.

gdb/ChangeLog:
2016-04-12  Pedro Alves  <palves@redhat.com>

	* mi/mi-interp.c (mi_new_thread): Put
	target_terminal_ours_for_output in effect while outputting.
	(mi_thread_exit): Use target_terminal_ours_for_output instead of
	target_terminal_ours.
	(mi_record_changed, mi_inferior_added, mi_inferior_appeared)
	(mi_inferior_exit, mi_inferior_removed, mi_traceframe_changed)
	(mi_tsv_created, mi_tsv_deleted, mi_tsv_modified)
	(mi_breakpoint_created, mi_breakpoint_deleted)
	(mi_breakpoint_modified, mi_solib_loaded, mi_solib_unloaded)
	(mi_command_param_changed, mi_memory_changed)
	(report_initial_inferior): Use target_terminal_ours_for_output
	instead of target_terminal_ours.  Restore terminal settings.
	* mi/mi-main.c (mi_execute_command): Use
	target_terminal_ours_for_output instead of target_terminal_ours.
	Restore terminal settings.
