* monitor.c: make_xmodem_packet and print_xmodem_packet go away.

Browse source 
send_xmodem_packet shows up to do the obvious.  Lots of fixes to
	xmodem downloads including resetting of block number at start of
	new transfers, fix for buffer overrun problem, addition of CRC
	generation code.
	* (monitor_open):  loadtype_str and loadproto_str now default to
	first entry in monitor_ops->loadtypes.
	* (monitor_wait):  Lengthen register dump buf, because of verbose
	Winbond monitor.
	* (monitor_fetch_register):  Report unimplemented registers as 0.
	* (monitor_read_memory):  Only do 16 byte aligned transfers
	because of formatting weirdness with the Winbond monitor.  Also,
	ignore non-hex, non-whitespace formatting between bytes (same
	monitor).
	* (monitor_load):  Clean up logic.
	* (monitor_load_srec):  Re-do xmodem support.  Move lots of it
	into send_xmodem_packet.
	* (getacknak):  Get rid of polls and timeouts.  Handle CRC
	requests from receiver.
	* (monitor_make_srec):  Efficiency improvements.  Don't call
	sprintf to output two digit hex numbers.
	* (crcinit, docrc):  New, CRC-16 support routines.
	* (send_xmodem_packet):  New routine to generate either CRC-16 or
	checksummed xmodem packets.

	* remote-est.c (est_loadtypes), rom68k-rom.c (rom68k_loadtypes):
	Reduce tables down to only the load types supported by each
	monitor.

	* w89k-rom.c  (w89k_supply_register):  Parses output of Winbond
	register dumps.
	* (w89k_loadtypes, w89k_loadprotos):  Reduce to just srec/xmodem.
	* (w89k_cmds):  Add clear all breakpoints, memory fill, and dump
	registers commands.
