core: make the intcall/farcall/cfarcall routines reentrant
Make the intcall/farcall/cfarcall routines reentrant, by dropping the
use of RealModeEAX and by saving/restoring Com32SysSP on the PM stack.
Furthermore, drop the saving and restoring of EAX, EDX, ECX; trying to
save all registers complicates the code, and those registers will be
assumed clobbered by the caller anyway. Might as well save a little
bit of stack space, too.
