* breakpoint.c (gdb_breakpoint_query): Update, use
	catch_exceptions_with_msg.
	(do_captured_breakpoint): Add uiout parameter.
	(gdb_breakpoint): Update, use catch_exceptions_with_msg.
	* mi/mi-main.c (mi_cmd_thread_select): Pass mi_error_message to
	gdb_thread_select.  Return MI_CMD_ERROR instead of
	MI_CMD_CAUGHT_ERROR.
	(mi_cmd_thread_list_ids): Ditto for gdb_list_thread_ids.
	(enum captured_mi_execute_command_actions): Delete
	EXECUTE_COMMAND_DISPLAY_ERROR.
	(captured_mi_execute_command): Delete code handling
	MI_CMD_CAUGHT_ERROR.
	(mi_execute_command): Don't check for
	EXECUTE_COMMAND_DISPLAY_ERROR.
	* mi/mi-cmd-break.c (breakpoint_notify): Update call to
	gdb_breakpoint_query.
	(mi_cmd_break_insert): Pass mi_error_message to gdb_breakpoint.
	* mi/mi-cmds.h (enum mi_cmd_result): Delete MI_CMD_CAUGHT_ERROR.
	* gdb.h (gdb_thread_select, gdb_list_thread_ids)
	(gdb_breakpoint, gdb_breakpoint_query): Add error_message
	parameter.
	* thread.c (thread_command): Update call.
	(gdb_thread_select, gdb_list_thread_ids): Update, call
	catch_exceptions_with_msg.
