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.
