provide __HAVE_COMPAT_NETBSD32 and fix multiple include protection consistently.

On ARM-ish ports having PCI support, use new-style <sys/bus.h>. Do not
install <machine/bus.h>. Remove various <machine/bus.h> sources.

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.

Generic soft interrupts are mandatory.

branches: 1.8.8; 1.8.16;
Convert the NetBSD/cats port to use generic TODR.

This gets rid of the now-unneded "todclock" and "todservice" attributes
from the footbridge device files, which should allow netwinder to build
again after its conversion to generic TODR.

Resulting kernel verified to boot up OK on gxemul (after my recent
fixes of the gxemul package to emulate free-running timers).

branches: 1.7.2;
Convert netwinder and cats (and any other footbridge based system in the
future) to timecounters, using the dc21285_fclk. ok nick@, chris@.

branches: 1.6.2;
Nothing in the kernel now tests __HAVE_NWSCONS, so stop defining it everywhere.

branches: 1.5.22; 1.5.36; 1.5.40;
Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

Use "#define<tab>".

End the "new ARM includes strategy" experiment. The new strategy
broke too many assumptions makde by other parts of the source tree,
and the strategy and how it was supposed to work was never discussed
on tech-userlevel, nor was it applied consistently (to all ARM ports
and to other ports which have common MACHINE_ARCH code, such as MIPS,
m68k, powerpc).

Verified to complete a full "make build" on cats, dnard, evbarm,
and netwinder.

Add 26-bit and 32-bit types.h files, which indicate the programming
model in use for a given platform (__PROG26 vs __PROG32), then pulls
in <arm/types.h>. Change each ARM port to pull in <arm/arm26/types.h>
or <arm/arm32/types.h> as appropriate. Change all references to PROG26
and PROG32 to __PROG26 and __PROG32. Eliminate the opt_progmode.h
header file.

branches: 1.1.2; 1.1.8;
Finish off the cats arch dir by creating an include dir and populating it from
arm32/include.
Make use of std.cats in the kernel config.

Fixup files.cats so it actually works.
