Welcome XENPVHVM mode.

It is UP only, has xbd(4) and xennet(4) as PV drivers.

The console is com0 at isa and the native portion is very
rudimentary AT architecture, so is probably suboptimal to
run without PV support.

Fix editing screwup in previous... noted by Rin Okuyama (thanks!)

Hide differences between i386 and amd64 interrupt frames so XEN does
not need to know there is one. Hopefully unbreak i386 build.

This doesn't need fpu.h, but should include ucontext.h

Move sys/arch/amd64/amd64/fpu.c and sys/arch/amd64/include/fpu.h
into sys/arch/x86 in preparation for using the same code for i386.

put the contents of these header files around #ifdef __x86_64__, and
#include the <i386/foo.h> in the #else clause, making these files
largely bit-size independant.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
