* 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.

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.

Simplify initialization and remove offending DMA channel resets there.
The resets trash whatever is pointed to DMA registers, but at cmi_attach()
time the DMA registers have not been initialized with valid addresses.

- Added 4 speaker enable to initialization sequence.
- Removed delays between register pokes which appear to aggravate a
problem this card has sampling at 44.1kHz. With any form of delay,
skew relative to system clock at 44.1kHz is usually in range 0-25%
(now 0-3%). No other rates exhibit this problem.
- Changed structs cmi_* to sc_*.

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.

last poke in sequence. Enabling SPDIF was coercing output rate to
48K, not good for 44.1K tracks.
