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.
