* remote.c (escape_buffer): New.

Browse Source 
(putpkt_binary, read_frame, getpkt_or_notif_sane_1): Use it.  Make
	sure debug output printing a packet buffer goes through a single
	fprintf_unfiltered call.
	* utils.c (vfprintf_unfiltered): If outputting timestamps, end
	output with a newline if it wasn't going to already.
