afadbf66cb - Clean up Aperture Access Global Enable (APEN) bit access.
- Rename confusing AGP_INTEL_I845_MCHCFG to AGP_INTEL_I845_AGPM.
- Move E7205 and E7505 from i8x5 to i8x0 family.  It probably worked
because the actual offset is the same.

In fact, all three families have the bit at the exact same place.  Only
differences are name and width of the registers, i.e., NBXCFG (0x50, dword),
RDCR (0x51, byte), AGPM (0x51, byte), MCHCFG (0x50, word) depending on
the family of the chipsets.

670b9e9fda Add code to parse the utrace(2) entries generated by malloc(3) in a more
human-readable format.  Note that we report 'realloc(p, 0)' as 'free(p)'
since both cases are encoded the same way and 'free()' is more common
than a realloc() to 0.

9ae328fc8f - Close a race between enumerating UNIX domain socket pcb structures via
sysctl and socket teardown by adding a reference count to the UNIX domain
  pcb object and fixing the sysctl that enumerates unpcbs to grab a
  reference on each unpcb while it builds the list to copy out to userland.
- Close a race between UNIX domain pcb garbage collection (unp_gc()) and
  file descriptor teardown (fdrop()) by adding a new garbage collection
  flag FWAIT.  unp_gc() sets FWAIT while it walks the message buffers
  in a UNIX domain socket looking for nested file descriptor references
  and clears the flag when it is finished.  fdrop() checks to see if the
  flag is set on a file descriptor whose refcount just dropped to 0 and
  waits for unp_gc() to clear the flag before completely destroying the
  file descriptor.

8ab80cf009 - ftick was initialized to -1 for init and any of it's children. Fix this by
setting ftick = ltick = ticks in schedinit().
 - Update the priority when we are pulled off of the run queue and when we
   are inserted onto the run queue so that it more accurately reflects our
   present status.  This is important for efficient priority propagation
   functioning.
 - Move the frequency test into sched_pctcpu_update() so we don't repeat it
   each time we'd like to call it.
 - Put some temporary work-around code in sched_priority() in case the tick
   mechanism produces a bad priority.  Eventually this should revert to an
   assert again.

3c3619cdad Convert compression_skip from taking a size_t skip length request and
returning the length skipped in a ssize_t to using off_t for both.  This
does not break any A[BP]Is, since compression_skip is entirely internal
to libarchive.

If a skip request is > SSIZE_MAX, don't pass it down to the client layer
skip function, since those still uses size_t / ssize_t.  Instead, just
read the data and throw it away.

With this commit, libarchive/bsdtar should now successfully skip archive
entries of >2GB on 32-bit systems, but does so slower than necessary.
The performance will improve with a future A[BP]I breaking commit which
makes client layer skip functions use off_t.

3f872f85d2 - Only allow the tdq_idx to increase by one each tick rather than up to
the most recently chosen index.  This significantly improves nice
   behavior.  This allows a lower priority thread to run some multiple of
   times before the higher priority thread makes it to the front of
   the queue.  A nice +20 cpu hog now only gets ~5% of the cpu when running
   with a nice 0 cpu hog and about 1.5% with a nice -20 hog.  A nice
   difference of 1 makes a 4% difference in cpu usage between two hogs.
 - Track a seperate insert and removal index.  When the removal index is
   empty it is updated to point at the current insert index.
 - Don't remove and re-add a thread to the runq when it is being adjusted
   down in priority.
 - Pull some conditional code out of sched_tick().  It's looking a bit
   large now.

e7d50326de ULE 2.0:
- Remove the double queue mechanism for timeshare threads.  It was slow
   due to excess cache lines in play, caused suboptimal scheduling behavior
   with niced and other non-interactive processes, complicated priority
   lending, etc.
 - Use a circular queue with a floating starting index for timeshare threads.
   Enforces fairness by moving the insertion point closer to threads with
   worse priorities over time.
 - Give interactive timeshare threads real-time user-space priorities and
   place them on the realtime/ithd queue.
 - Select non-interactive timeshare thread priorities based on their cpu
   utilization over the last 10 seconds combined with the nice value.  This
   gives us more sane priorities and behavior in a loaded system as
   compared to the old method of using the interactivity score.  The
   interactive score quickly hit a ceiling if threads were non-interactive
   and penalized new hog threads.
 - Use one slice size for all threads.  The slice is not currently
   dynamically set to adjust scheduling behavior of different threads.
 - Add some new sysctls for scheduling parameters.

Bug fixes/Clean up:
 - Fix zeroing of td_sched after initialization in sched_fork_thread() caused
   by recent ksegrp removal.
 - Fix KSE interactivity issues related to frequent forking and exiting of
   kse threads.  We simply disable the penalty for thread creation and exit
   for kse threads.
 - Cleanup the cpu estimator by using tickincr here as well.  Keep ticks and
   ltick/ftick in the same frequency.  Previously ticks were stathz and
   others were hz.
 - Lots of new and updated comments.
 - Many many others.

Tested on:	up x86/amd64, 8way amd64.

3fed7d239a - Add three new functions to support circular run queues.
- runq_add_pri allows the caller to position the thread at any rqindex
   regardless of priority.
 - runq_choose_from() chooses the lowest priority thread starting from a given
   index.  The index is updated with the rqindex of the chosen thread.  This
   routine is used to pick the lowest priority relative to a given index.
 - runq_remove_idx() updates the index if the run queue that held the removed
   thread is now empty.

4c8dc49a4a Add auto_if_type() function, which is similar to auto_switch_type().
However, auto_if_type() uses if/else statements in C instead
of a single switch statement, when mapping an integer value to
a #define.  For certain cases where multiple #define constants
alias to a single integer value, auto_if_type() makes things easier
to parse than auto_switch_type().
