	* target.h: Put remote_debug declaration back here.  Add baud_rate.
	* remote.c, remote-udi.c, remote-utils.h: Let target.h take care of

	* Move "set remotebaud" from remote-utils.c to main.c to it applies
	to remote.c as well.

	* xcoffread.c (xcoff_symfile_read), coffread.c (coff_symfile_read):
