67b1dce3bc many changes:
* add new channels to the end of the list so channels used in order of
addition

* de-globalise definition of struct snddev_info and provide accessor
functions where necessary.

* move the $FreeBSD$ tag in each .c file into a macro and allow the
/dev/sndstat handler to display these when set to maximum verbosity to aid
debugging.

* allow each device to register its own sndstat handler to reduce the amount
of groping sndstat must do in foreign structs.

d95502a838 use a global devclass for all drivers - i'm not entirely sure why this
worked before.

mixer, dsp and sndstat are seperate devices - give them their own cdevsws
instead of demuxing requests sent to a single cdevsw.

use the si_drv1/si_drv2 fields in dev_t structures for holding information
specific to an open instance of mixer/dsp.

nuke /dev/{dsp,dspW,audio}[0-9]* links - this functionality is now provided
using cloning.

various locking fixes.

66ef8af5b0 mega-commit.
this introduces a new buffering mechanism which results in dramatic
simplification of the channel manager.

as several structures have changed, we take the opportunity to move their
definitions into the source files where they are used, make them private and
de-typedef them.

the sound drivers are updated to use snd_setup_intr instead of
bus_setup_intr, and to comply with the de-typedefed structures.

the ac97, mixer and channel layers have been updated with finegrained
locking, as have some drivers- not all though.  the rest will follow soon.

350a5fafb1 update code dealing with snd_dbuf objects to do so using a functional interface
modify chn_setblocksize() to pick a default soft-blocksize appropriate to the
sample rate and format in use.  it will aim for a power of two size small
enough to generate block sizes of at most 20ms.  it will also set the
hard-blocksize taking into account rate/format conversions in use.

update drivers to implement setblocksize  correctly:
updated, tested: 	sb16, emu10k1, maestro, solo
updated, untested: 	ad1816, ess, mss, sb8, csa
not updated: 		ds1, es137x, fm801, neomagic, t4dwave, via82c686

i lack hardware to test: ad1816, csa, fm801, neomagic
others will be updated/tested in the next few days.

0f55ac6c1a kobjify.
this gives us several benefits, including:

* easier extensibility- new optional methods can be added to
  ac97/mixer/channel classes without having to fixup every driver.

* forward compatibility for drivers, provided no new mandatory methods are
  added.

306f91b60b detach support
remove un-needed setdir functions
add bus_teardown_intr calls where necessary

33dbf14a17 change mixer api slightly
change channel interface - kobj implementation coming soonish
make pcm_makelinks not panic if modular
add pcm_unregister()

these changes support newpcm kld unloading, but this is only implemented
by ds1.c

513693be6c rework feeder sytem to allow feeders in klds
modify driver capability reporting format to list every audio format
seperately- required for above and because we could not previously indicate
that mono was unsupported.

there should be no functional impact.

6c1146c0b8 fix the staticy sound issue
use timer instead of per-channel interrupts

do playback like the linux driver - may fix nmi-with-ecc issue

f314f3dad2 add module metadata. this is a hack, sound drivers will eventually present a
bus to which pcm, mixer, etc will attach.

70776a9c0b add alpha-quality recording code and handle pci error interrupts - this may
prevent the card generating an nmi on ecc systems.  for now a message is
printed on every pci error and it seems every time we start playng we get one

e39756439c Back out the previous change to the queue(3) interface.
It was not discussed and should probably not happen.

740a1973a6 Change the way that the queue(3) structures are declared; don't assume that
the type argument to *_HEAD and *_ENTRY is a struct.

c067afaa06 unfinished sblive driver, playback/mixer only for now - not enabled in
conf/files

i don't seem to be clearing the cache right resulting in a short initial
burst of noise, despite doing the same as creative and alsa.  i'm committing
now so more eyes can pore over the code.
