All: Declare sim_stop_messages as an array SCPE_BASE long

Browse Source 
This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof

Update simh.doc to reflect this generic change.
