no longer possible to unload the driver module while sound is playing
  (which resulted in a panic).

instead of using two malloced arrays for storing channel lists, use an
slist.  convert the sndstat device to use sbufs and optionally provide more
detail about channel state.

vchans are software mixed playback channels.  they are not enabled by this
commit.  they use the feeder infrastructure to emulate normal playback
channels in a manner transparent to applications, whilst providing as many
channels are desired, especially suitable for devices with only one hardware
playback channel.  in the future they will provide additional features.

those wishing to test this functionality will need to add vchan.c to
sys/conf/files and use 'sysctl -w hw.snd.pcm0.vchans' to enable it.

other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.

The resets trash whatever is pointed to DMA registers, but at cmi_attach()

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.

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.

devices.  opening /dev/{dsp,dspW,audio}0 and then opening a different device

performed on the first fd.

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