- Fix a few possible locking issues in execve1() and exit1().  Add a note
  that scheduler locks are special in this regard - adaptive locks cannot
  be in the path due to turnstiles.  Randomly spotted/reported by uebayasi@.
- Remove unused lwp_relock() and replace lwp_lock_retry() by simplifying
  lwp_lock() and sleepq_enter() a little.
- Give alllwp its own cache-line and mark lwp_cache pointer as read-mostly.

Enable blocking synchronization for callouts as discussed at length on
tech-kern last year. Instead of modifying callout_stop, add a new
routine (callout_halt) which will sleep if the callout is already in
flight. Note that if a callout can take locks, the caller of callout_halt
must not hold any of those locks - otherwise the two could deadlock.

Merge scheduler changes from the vmlocking branch. All discussed on
tech-kern:

- Invert priority space so that zero is the lowest priority. Rearrange
  number and type of priority levels into bands. Add new bands like
  'kernel real time'.
- Ignore the priority level passed to tsleep. Compute priority for
  sleep dynamically.
- For SCHED_4BSD, make priority adjustment per-LWP, not per-process.

- Fix interactivity problems under high load. Beacuse soft interrupts
  are being stacked on top of regular LWPs, more often than not aston()
  was being called on a soft interrupt thread instead of a user thread,
  meaning that preemption was not happening on EOI.

- Don't use bool in a couple of data structures. Sub-word writes are not
  always atomic and may clobber other fields in the containing word.

- For SCHED_4BSD, make p_estcpu per thread (l_estcpu). Rework how the
  dynamic priority level is calculated - it's much better behaved now.

- Kill the l_usrpri/l_priority split now that priorities are no longer
  directly assigned by tsleep(). There are three fields describing LWP
  priority:

        l_priority: Dynamic priority calculated by the scheduler.
                This does not change for kernel/realtime threads,
                and always stays within the correct band. Eg for
                timeshared LWPs it never moves out of the user
                priority range. This is basically what l_usrpri
                was before.

        l_inheritedprio: Lent to the LWP due to priority inheritance
                (turnstiles).

        l_kpriority: A boolean value set true the first time an LWP
                sleeps within the kernel. This indicates that the LWP
                should get a priority boost as compensation for blocking.
                lwp_eprio() now does the equivalent of sched_kpri() if
                the flag is set. The flag is cleared in userret().

- Keep track of scheduling class (OTHER, FIFO, RR) in struct lwp, and use
  this to make decisions in a few places where we previously tested for a
  kernel thread.

- Partially fix itimers and usr/sys/intr time accounting in the presence
  of software interrupts.

- Use kthread_create() to create idle LWPs. Move priority definitions
  from the various modules into sys/param.h.

- newlwp -> lwp_create

- Alter the callout ABI to be stable in the event of changes to the
  internal data structures.
- Add a flags argument to callout_init(). If CALLOUT_MPSAFE is specified,
  the kernel lock is not taken when the callout is executed.
- Only synchronize with running callouts from callout_stop(). If the
  callout is MP safe, then sleep until it has completed. If it is not
  MP safe (and thus should not block) use the kernel lock to provide
  synchronization. Both need to be verified as deadlock free, but at
  this time I think they are OK.

  less expensive.  Add a comment that the compiler is likely to unroll
  the loop (so don't sweat that it's there).

Temporarily introduce CALLOUT_INVOKING, callout_invoking() and callout_ack()
to make users of the callout facility able to cooperate to work around the
race caused by the callout code lowering interrupt priority level when
invoking callout handlers, something which allows other code to run before
the callout handler gets to it's spl*() call.

This is to enable the workaround for the TCP code found in PR#20390 to be
applied.

This should be backed out once a more comprehensive fix can be put in
place.

New callout implementation.  This is based on callwheel implementation
done by Artur Grabowski and Thomas Nordin for OpenBSD, which is more
efficient in several ways than the callwheel implementation that it is
replacing.  It has been adapted to our pre-existing callout API, and
also provides the slightly more efficient (and much more intuitive)
API (adapted to the callout_*() naming scheme) that the OpenBSD version
provides.

Among other things, this shaves a bunch of cycles off rescheduling-in-
the-future a callout which is already scheduled, which the common case
for TCP timers (notably REXMT and KEEP).

The API has been simplified a bit, as well.  The (very confusing to
a good many people) "ACTIVE" state for callouts has gone away.  There
