4ba8d09fe2 Change MIPS simulator so that it uses the (software) module sim_fpu

aaa11abe42 Clarify meaning of sim_signalled's SIGRC argument. Document that this 
isn't possible in sim-reason.c and just return the target SIGRC
instead.

For simulators that rely on sim-reason.c, replace SIG* with SIM_SIG*.

Hack nrun.c so that when it is executed (ARGV[0]) as `step' instead
of `run' it single steps the simulator.  Allows testing of single step
without full GDB.

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).
