Make sure interrupts are disabled during cpu_configure(9).

Fixes 'panic: kernel diagnostic assertion "cv_is_valid(cv)" failed'
during fdcisa(4) probe on Milan's DIAGNOSTIC kernel, caused by
a stray interrupt from the FDC right after isa_intr_establish().
No visible bad side effect on TT030 with this change.

Should be pulled up to netbsd-8.

G/C a couple of lingering instances of addupc(). There is still some bit-
rotten profiling code that references it, but that code is already almost
certainly broken for other reasons.

Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

Fix silent hang after isa_intr_establish() on Milan.

The problems (wrong macro replacements) were slipped in rev 1.107:

Merge m68881_save() and m68881_restore() (using most common mvme68k ones).
All functions are checked by my eyes, and all GENERIC kernels compile.

hardcording them in locore.s and vector.s
- also make interrupt handlers take per unit softc and put a softint cookie
into softc (though atari machines have only one zs)
- tweak some structures as per MI z8530sc driver

Tested on TT030 using sl(4) on zs.

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.

Pass a frame pointer to trap() rather than the 'entire frame' trick. Gcc4
was optimizing away modifications to the frame contents (it's not nice to
trick gcc). Pass the pointer as the first argument to reduce the number
of places that would be changed otherwise. Fixes the getcwd regression
test on most m68k ports.

The l_next and l_back fields in struct lwp no longer exists, so delete
references to it from genassym.cf.
Also, m68k/m68k/proc_subr.s is no longer used, says mhitch, so remove its use.

This brings the atari BOOT kernel back to a buildable state.
