Remove dependency on misc.h from sim.h

Include string.h to declare strerror
Remove rig.h from simic705.c

From first principles, none of the simulators should use *ANY* of the
code from Hamlib.  Using the same code on both sides of a simulation gives
the equivalent of a math "X = X" proof; guaranteed to work, but useless
for proving anything else.
