cee687386d * 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.

8517f62b16 Ref gdb/11763 - can't stop a running simulator: 
o	Provide poll_quit callback to simulators
		so that they can poll for SIGINT on
		clueless OS's.

	o	Add sim_stop to simulators so that clients
		can request a halt (eg gdbtk's STOP button)
		Works for PPC!

	o	Re-arange remote-sim.c so that the
		hard work is moved from gdbsim_resume()
		to gdbsim_wait() (where it should be).
