fbb8b6b9ab For sim_fetch_register / sim_store_register: Add LENGTH parameter, 
return actual size of register, 0 if not applicable, -1 of legacy
implementation.

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.

247fccdeb5 Add ABFD argument to sim_open call. Pass through to sim_config so 
that image properties such as endianness can be checked.

More strongly document the expected behavour of each of the sim_*
interfaces.

Add default endian argument to simulator config macro
SIM_AC_OPTION_ENDIAN.  Use in sim_config.
