8b330062da Centralize DMA buffer configuration. 
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.

417f47c4d5 - Added suspend/resume support. 
- 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_*.

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.

64738af72b add support for opti924 and opti930 chips 
both should work in non-pnp mode, the 924 should also work in its rather
braindead pnp mode- it will adopt port 0x530 unless given hints due to it
starting up in soundblaster mode and thus not requesting a valid mss port
address.

9a1ec7ebfd fix a panic triggerable by anyone with read/write access to the audio 
devices.  opening /dev/{dsp,dspW,audio}0 and then opening a different device
from that list and closing it resulted in a panic when any operation is
performed on the first fd.

we prevent this happening by denying the second open unless it uses the same
minor device as the first.

87a636ccb0 - Mutexify midi(4). The driver runs under the giant lock by default. 
If you ever want to run midi(4) out of the giant lock, uncomment
MIDI_OUTOFGIANT in midi.h. Confirmed to work for csamidi with WITNESS
and INVARIANTS.

- midi_info, midi_open and seq_info are now tailqs, allowing arbitrary
numbers of devices to be configured.

- Do not send an active sensing message to reset midi modules.

- Clone /dev/sequencer*. /dev/sequencer0 and /dev/sequencer are generated
upon initialization.
