cs4281(4): Fix lock ordering in suspend.

No idea if this code works -- obviously this path has never been
tested in the >decade it's been here!

Sync with HEAD.

Remove code no longer used.
The code that used sc->{halt_input,halt_output} function pointer
was removed in 2004. (see cs428x.c rev 1.7)

Whitespace nit.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly.  Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism.  The encoding/channels/frequency
  conversions are completely handled in the upper layer.  So the hard-
  ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
  - Obsoletes query_encoding and add query_format instead.
  - Obsoletes set_params and add set_format instead.
  - Remove drain, setfd, mappage.
  - The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c         -> dev/audio/audio.c (rewritten)
- dev/audiovar.h      -> dev/audio/audiovar.h
- dev/audio_dai.h     -> dev/audio/audio_dai.h
- dev/audio_if.h      -> dev/audio/audio_if.h
- dev/audiobell.c     -> dev/audio/audiobell.c
- dev/audiobellvar.h  -> dev/audio/audiobellvar.h
- dev/mulaw.[ch]      -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

Move dev/audio_if.h -> dev/audio/audio_if.h

Adapt cs428x families to audio2.
- recording on cs4280 seems to have its own conversion.
  I will see it later but first make it compilable.

Use C99 style struct initializer to audio_hw_if.

Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive}
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.

put back IPL_AUDIO and splaudio(), at the request of rmind.  they are
aliases and now we can easily revert audio to IPL_VM if necessary,
without having to revert the whole branch.

Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:

  Add MP locking to the audio drivers.

  Making the audio drivers MP safe is necessary before efforts
  can be made to make the VM system MP safe.

  The are two locks per device instance, an ISR lock and
  a character device lock. The ISR lock replaces calls to
  splaudio()/splx(), and will be held across calls to device
  methods which were called at splaudio() before (e.g.
  trigger_output). The character device lock is held across
  calls to nearly all of the methods, excluding some only
  used for initialization, e.g. get_locks.

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

Expand PMF_FN_* macros.

Refactor PNP API:
- Make suspend/resume directly a device functionality. It consists of
  three layers (class logic, device logic, bus logic), all of them being
  optional. This replaces D0/D3 transitions.
- device_is_active returns true if the device was not disabled and was
  not suspended (even partially), device_is_enabled returns true if the
  device was enabled.
- Change pnp_global_transition into pnp_system_suspend and
  pnp_system_resume. Before running any suspend/resume handlers, check
  that all currently attached devices support power management and bail
  out otherwise. The latter is not done for the shutdown/panic case.
- Make the former bus-specific generic network handlers a class handler.
- Make PNP message like volume up/down/toogle PNP events. Each device
  can register what events they are interested in and whether the handler
  should be global or not.
- Introduce device_active API for devices to mark themselve in use from
  either the system or the device. Use this to implement the idle handling
  for audio and input devices. This is intended to replace most ad-hoc
  watchdogs as well.
- Fix somes situations in which audio resume would lose mixer settings.
- Make USB host controllers better deal with suspend in the light of
  shared interrupts.
- Flush filesystem cache on suspend.
- Flush disk caches on suspend. Put ATA disks into standby on suspend as
  well.
- Adopt drivers to use the new PNP API.
- Fix a critical bug in the generic cardbus layer that made D0->D3
  break.
- Fix ral(4) to set if_stop.
- Convert cbb(4) to the new PNP API.
- Apply the PCI Express SCI fix on resume again.

merge kent-audio1 branch, which introduces audio filter pipeline to the MI
audio framework


Summary of changes:

* struct audio_params
  - remove sw_code, factor, factor_denom, hw_sample_rate,
hw_encoding ,hw_precision, and hw_channels.  Conversion information
is conveyed by stream_filter_list_t.
  - change the type of sample_rate: u_long -> u_int
  - add `validbits,' which represents the valid data size in
precision bits.  It is required in order to distinguish 24/32bit
from 24/24bit or 32/32bit.

* audio_hw_if
 - add two parameters to set_params()
	stream_filter_list_t *pfil, stream_filter_list *rfil
   A HW driver should set filter recipes for requested formats
 - constify audio_params parameters of trigger_output() and
trigger_input().  They represent audio formats for the hardware.
 - make open() and close() optional
 - add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters
 to round_blocksize()

* sw_code is replaced with stream_filter_t.
  stream_filer_t converts audio data in an input buffer and writes
into another output buffer unlike sw_code, which converts data in
single buffer.
  converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c,
dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are
reimplemented as stream_filter_t

* MI audio
 - audiosetinfo() builds filter pipelines from stream_filter_list_t
filled by audio_hw_if::set_params()
 - audiosetinfo() returns with EINVAL if mmapped and set_params()
requests filters
 - audio_write(), audio_pint(), and audio_rint() invoke a filter
pipeline.
 - ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS,
AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for
AUDIO_GETINFO handle values for a buffer nearest to userland.

* add `struct device *' parameter to ac97_attach()

* all of audio HW drivers follow audio_hw_if and ac97 changes

audio_hw_if change
 * make open() and close() optional
 * add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters
 to round_blocksize()

* remove stream_filter_list_append and stream_filter_list_prepend
* add stream_filter_list_t::{append(), prepend(), set()}

* adopt the filter pipeline framework
* follow ac97_attach() change
