85f190e4d1 Fixes to make select/poll mpsafe.
Problem:
  selwakeup required calling pfind which would cause lock order
  reversals with the allproc_lock and the per-process filedesc lock.
Solution:
  Instead of recording the pid of the select()'ing process into the
  selinfo structure, actually record a pointer to the thread.  To
  avoid dereferencing a bad address all the selinfo structures that
  are in use by a thread are kept in a list hung off the thread
  (protected by sellock).  When a selwakeup occurs the selinfo is
  removed from that threads list, it is also removed on the way out
  of select or poll where the thread will traverse its list removing
  all the selinfos from its own list.

Problem:
  Previously the PROC_LOCK was used to provide the mutual exclusion
  needed to ensure proper locking, this couldn't work because there
  was a single condvar used for select and poll and condvars can
  only be used with a single mutex.
Solution:
  Introduce a global mutex 'sellock' which is used to provide mutual
  exclusion when recording events to wait on as well as performing
  notification when an event occurs.

Interesting note:
  schedlock is required to manipulate the per-thread TDF_SELECT
  flag, however if given its own field it would not need schedlock,
  also because TDF_SELECT is only manipulated under sellock one
  doesn't actually use schedlock for syncronization, only to protect
  against corruption.

Proc locks are no longer used in select/poll.

a0eed7bc1c Add a sysctl, sysctl hw.snd.report_soft_formats, that controls whether the
AIOGCAP ioctl reports software-emulated formats.  It defaults to on.  People
who use performance-sensitive audio software and do not want it to pick a
software-emulated audio format instead of one supported by their hardware
should turn it off.

This unbreaks isdnphone(1) on systems with PCM-only sound cards.

60d1d6861b Recent changes to newpcm require that the CHANNEL_SETFORMAT op return 0
for success, non-zero otherwise.  The maestro and maestro3 drivers were
returning the format code, which was being interpreted as a failure code.
Fixed.  No one seems to have noticed that the maestro driver was broken,
but I'll fix it anyways.

79e6a82b48 make the feederchain builder work for recording. this has not been tested
extensively as none of my testboxes have speakers or an audio source at
present, but the chains built look correct and reading /dev/audio (ulaw,
translated from signed 16 bit little-endian) gives values within the
expected range for silence.

bd8e0aee01 Change ich_calibrate to busy wait on buffer fill level and use a more
likely looking rate calculation.

Install interrupt handler before calling ich_init as the initialization
occasionally generates spurious interrupts.

These changes are derived from cg's work in progress version of this
driver.

7e1f6dfe9d Modify the critical section API as follows:
- The MD functions critical_enter/exit are renamed to start with a cpu_
  prefix.
- MI wrapper functions critical_enter/exit maintain a per-thread nesting
  count and a per-thread critical section saved state set when entering
  a critical section while at nesting level 0 and restored when exiting
  to nesting level 0.  This moves the saved state out of spin mutexes so
  that interlocking spin mutexes works properly.
- Most low-level MD code that used critical_enter/exit now use
  cpu_critical_enter/exit.  MI code such as device drivers and spin
  mutexes use the MI wrappers.  Note that since the MI wrappers store
  the state in the current thread, they do not have any return values or
  arguments.
- mtx_intr_enable() is replaced with a constant CRITICAL_FORK which is
  assigned to curthread->td_savecrit during fork_exit().

2ae4ee833d Added a sysctl control variable "ac97rate" to allow manual tuning of
the link rate - some ich motherboards overclock ac97 out of the box.

Will hopefully replace this with a callibration loop in time for 4.5R
freeze.

Problem reported by Luigi Rizzo and fix derived from his code (put
diff in ich.c rather than ac97.c).
