* sparclet-rom.c: Remove includes of Unix system files.
Add function "sparclet_supply_register" so that parse_register_dump
will not seg-fault by calling a null function pointer.
Remove XMODEM support (unfinished work?).
Remove flag "MO_HANDLE_NL", so monitor's output can be read by humans.
Add fill command.
Remove colon from getreg.resp_delim so PSR register will work.
Remove pointer to sparclet_load (downloading SREC's doesn't work).
Null out local register names for %g0, all %cc and all %asr regs,
since the monitor can't report them. Will return zero instead.
* sparclet-stub.c: New -- remote protocol support for sparclet CPU.
* config/sparc/tm-sparclet.h: Re-arrange REGISTER_NAMES:
Add back %g0 and %psr, add %cc coprocessor regs, add %asr regs.
Adjust NUM_REGS and REGISTER_BYTES accordingly
