* monitor.c: Move all xmodem stuff into xmodem.[ch]. Remove

	unnecessary remoteloadprotocol and remoteloadtype support.
	* (expect expect_prompt):  Change names to monitor_expect and
	monitor_expect_prompt.  Make them global.
	* (printf_monitor):  Change name to monitor_printf.  Make global.
	* (monitor_read_memory):  Flush command echo to avoid parsing
	ambiguity with CPU32Bug monitor.
	* (monitor_load):  Remove remoteloadprotocol and remoteloadtype
	support.  Call target_ops->load_routine, default to
	monitor_load_srec.
	* (monitor_load_srec):  Remove everything but S-record support.
	* monitor.h (monitor_ops):  Add load_routine to provide monitor
	specific download capability.
	* remote-est.c:  Clean up copyrights and comments.
	* w89k-rom.c:  Use new xmodem support.
	* xmodem.c xmodem.h:  New files to support xmodem downloads.
	* rom68k-rom.c remote-est.c:  Fix copyrights, add load_routine
	entry to monitor_ops.
	* cpu32bug-rom.c:  New file to support Moto BCC debuggers.
	* config/m68k/est.mt (TDEPFILES):  Add cpu32bug.o.
	* config/pa/hppapro.mt (TDEPFILES):  Add xmodem.o.
