525d929e49 Rewrite sim_monitor (implements read, write, open, et.al. system 
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write.  This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
