Fix up the mac68k interrupt handlers to work with the new style common
clockframe layout and remove the CLOCK_FORMAT0 work-around. As a nice
side-effect, this also eliminates the super-sketchy stack unwinding used
by rtclock_intr to get at the interrupt stack frame.

operations to access the PRAM RTC, etc. in the IIsi and Cuda cases.
Thanks to Martin Husemann for pointing out the flaw.

This is a slightly more thorough workaround for the issue Martin found
in PR 37611, as it affected more than just adb_read_date_time().

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.

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.
