(sim_create_inferior): Get start address from abfd not prog_bfd.
(xfer_mem): Do bounds checking on addresses and return zero length
read/write on bad addresses, rather than aborting. Prepare to
be able to handle xfers that cross segment boundaries, but not
yet implemented. Only emit debug message when d10v_debug is
set as well as DEBUG being defined.
