* findvar.c (read_register_bytes write_register_bytes): Make

	these routines much smarter about updating registers from the
	target, only doing so when absolutely necessary.  This really
	speeds up register modification on some remote targets.

	* monitor.c:  More cleanups.  Get rid of monitor_load_ascii_srec.
	BFD makes this unnecessary.  Lots of debugging speedups.
	* (expect):  NULL terminate return string.
	* (monitor_open	monitor_supply_register parse_register_dump
	monitor_wait monitor_fetch_register):  Switch to using GNU regexp
	library to parse multi-register displays.
	* (monitor_read_memory): Read multiple bytes (up to 16) at once.
	* (monitor_create_inferior):  Call clear_proceed_status to make run
	command notice first breakpoint.
	* (monitor_load):  Clean up.  Reset inferior_pid, set pc to start
	address and reset symbol table stuff to make loads put things into
	a fresh state.
	* (monitor_load_srec):  Lower sleep time to 1 second.

	* monitor.h (struct monitor_ops):  Add register_pattern and
	supply_register to monitor_ops.

	* rom68k-rom.c:  Add new support for handling register dumps.
