	* tracepoint.h (struct trace_status): New fields disconnected_tracing
	and circular_buffer.
	(disconnect_tracing): Rename from disconnect_or_stop_tracing.
	* tracepoint.c (trace_status_command): Display target's status for
	disconnected tracing and circular buffer.
	(disconnect_tracing): Rename from disconnect_or_stop_tracing, add
	query for non-disconnected-tracing case, remove the stop_tracing
	call.
	(tfile_open): Clear disconnected and circular buffer status.
	(trace_save): Save disconnected and circular buffer status.
	(parse_trace_status): Parse disconnected and circular buffer status,
	also recognize disconnected as a stop reason.
	* remote.c (remote_set_disconnected_tracing): Only set
	QTDisconnected if the remote end supports disconnected tracing.
	Warn otherwise, if trying to enable disconnected tracing.
	* infcmd.c (detach_command): Update disconnect_tracing call.
	* cli/cli-cmds.c (quit_command): Ditto.

	* gdb.texinfo (Tracepoint Packets): Describe disconn and circular
	trace status fields.
