to support hotplug media on most architectures. disklabel setup and
verification done using new helper functions. Disklabels must *always*
have a correct checksum now. Same code paths are used to learn on-disk
location disklabels, to avoid new errors sneaking in. Tested on almost all
cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn

*_LABELOFFSET. Don't use osdep->labelsector since it will always be
LABELSECTOR, since we don't support extended DOS partitions holding
the OpenBSD disk label.
No functional change. Now only Alpha and Vax bounds_check_with_label
differ by more than comments.

mbuf constants from MD param.h to MI param.h.
Besides being the same on every arch, things will
most probly break if any arch has different values
then the others.
The NMBCLUSTERS constants needs to be MD though;

device_register() function -- even if it does nothing. reduces the
cpp-based blather different between architectures
idea ok'd by miod; tested on all architectures (except a few miod will
need to cleanup because he has them)

it's a good idea to use atomic.h operations on it. This mechanic
change updates all bit operations on p_flag to atomic_{set,clear}bits_int.
Only exception is that P_OWEUPC is set by MI code before calling
need_proftick and it's automatically cleared by ADDUPC. There's
no reason for MD handling of that flag since everyone handles it the
same way.

rt and such; tested and ok miod drahn

right now that are supposed to be atomic with respect to interrupts and
SMP: atomic_setbits_int and atomic_clearbits_int.
All architectures other than i386 and amd64 get dummy implementations
since at first we'll be replacing operations that are done with
"a |= bit" and "a &= ~bit" today. More proper implementations will follow

"The dosparts member of cpu_disklabel was not used for any persistant

don't have wd* in GENERIC, since wd* is the only place such info is
being used. First step of eliminating bad144 bad sector info from all
disklabels.

As DEV_BSHIFT is always 9, this should be a no-op.

DOS MBR' logic.
Leave DOS MBR logic inside #if defined(DISKLABEL_I386) blocks until
impact on install media can be evaluated. Eliminates most remnants
of cross-endian, cross-architecture disklabel processing attempts.
Fix some mips64 issues with last commit, found by kettenis@.
No functional change.

disklabel code that was intended to support cross-endian and cross-architecture
use of disklabels. Never actually used except for Alpha<->Amiga moves that now
can't happen anyway.
Leave native and DOS MBR disklabel code. Tested on alpha and hppa.

everyone for the prompt review and ok of this work ;-) Yeah, that includes me
too, or maybe especially me. I am sorry.
Change the sched_lock to a mutex. This fixes, among other things, the infamous
"telnet localhost &" problem. The real bug in that case was that the sched_lock
which is by design a non-recursive lock, was recursively acquired, and not
enough releases made us hold the lock in the idle loop, blocking scheduling
on the other processors. Some of the other processors would hold the biglock though,
which made it impossible for cpu 0 to enter the kernel... A nice deadlock.
Let me just say debugging this for days just to realize that it was all fixed
in an old diff noone ever ok'd was somewhat of an anti-climax.
This diff also changes splsched to be correct for all our architectures.
