* interp.c (UMEM_SEGMENTS): New define, set to 128.

(sim_size): Use UMEM_SEGMENTS rather than hardwired constant.
(sim_close): Reset prog_bfd to NULL after closing it. Also
reset prog_bfd_was_opened_p after closing prog_bfd.
(sim_load): Reset prog_bfd_was_opened_p after closing prog_bfd.
(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.
