* 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
