* dve3900-rom.c: New file to support Densan DVE-R3900/20 board.

	* monitor.c (monitor_debug): Move to utils.c, rename to puts_debug.
	(monitor_write_memory, monitor_read_memory, monitor_insert_breakpoint,
	monitor_remove_breakpoint): Remove useless address bits if current
	monitor has MO_ADDR_BITS_REMOVE flag.
	* monitor.h (MO_ADDR_BITS_REMOVE): Define.
	* utils.c (puts_debug): Formerly monitor_debug from monitor.c;
	move here and make public.  Add better support for carriage returns.
	* defs.h (puts_debug): Declare.
	* dsrec.c (load_srec): Use puts_debug to print remotedebug information.
	Output header record correctly.
	(make_srec): Output a header record instead of a termination record
	if sect is non-NULL (value is ignored), but abfd is NULL.
	* config/mips/tm-tx39.h (DEFAULT_MIPS_TYPE): Remove definition.
	(REGISTER_NAMES): Define to add R3900-specific registers.
	* config/mips/tm-tx39l.h: Ditto.
	* config/mips/tx39.mt (TDEPFILES): Add dve3900-rom.o and support files.
	* config/mips/tx39l.mt: Ditto.
