Add x86emu for in-kernel use. This is a 386 real mode emulator that can

be used to run ROM code inside the kernel without having to setup vm86
and without having a x86 CPU at hand.
This code was originally written by SciTech and released under MIT/X11
license for XFree86. It has been refactored be less than half of the
original size, the compiled code being around a third of the former
size. The interface was changed to be a real library, e.g. no global
variables are used.
