provide __HAVE_COMPAT_NETBSD32 and fix multiple include protection consistently.

Switch MIPS and MIPS-ish architectures to new-style <sys/bus.h>. This
involves moving some inline bus_space(9) implementation into .c files.

Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants,
remove the conditionals and the code associated with the undef case.

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.

Convert to common mips3_cp0_counter clock.
Convert to timecounters.

From Rivo Nurges (rix at estpak dot ee). ok soren@, tested by simon@.
Note that this means we aren't using the gt clock, and maybe we should clean
that up a bit.

Switch cobalt to MI todr.

merge ktrace-lwp.

Use common mips generic software interrupt routines.

Use "#define<tab>".

Some cleanups.
