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.

x86 changes for pcc and LKMs.

- Replace most inline assembly with proper functions. As a side effect
this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
smaller amount. Nearly all of the inlines did something slow, or something
that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.

__unused removal on arguments; approved by core.

- sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386

add missing initializers.

Revert previous (in line with <i386/mtrr.h> reversion).

make k6_mtrr_funcs, i686_mtrr_funcs and mtrr_funcs const
remove extern definition for i686_mtrr_funcs from include/mtrr.h, it's
not used outside mtrr_i686.c

Fix MTRR code which had been broken since the MP merge (but silently
failed due to a missing include of opt_mtrr.h in cpu.c)

Follow AMD's recommendations for programming the uncachable/write-combine
bits of the K6 cache-control-register: disable the cache; flush the cache;
set the bits; re-enable the cache (all much like programming the pentium
mtrr's). See reference posted to tech-kern; also review there by thorpej.
