Andrew Cagney 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.

Jeff Law d05b86b7fb * interp.c (sim_resume): Clear State.exited.
