Last patch for this driver (against -CURRENT): snd_emu10kx_70_patch8

Update snd_emu10kx driver with recent perforce changes (and some
other changes too).

(without any real order)

1. Use device_get_nameunit for mutex naming
2. Add timer for low-latency playback
3. Move most mixer controls from sysctls to mixer(8) controls. This
is a largest part of this patch.
4. Add analog/digital switch (as a temporary sysctl)
5. Get back support for low-bitrate playback (with help of (2))
6. Change locking for exclusive I/O. Writing to non-PTR register
is almost safe and does not need to be ordered with PTR operations.
7. Disable MIDI until we get it to detach properly and fix memory
managment problems.
8. Enable multichannel playback by default. It is as stable as
single-channel mode. Multichannel recording is still an experimental
feature.
9. Multichannel options can be changed by loader tunables.
10. Add a way to disable card from a loader tunable.
11. Add new PCI IDs.
12. Debugger settings are loader tunables now.
14. Remove some unused variables.
15. Mark pcm sub-devices MPSAFE.
16. Partially revert rev. 1.9 changes by ariff@ (bus_setup_intr -> snd_setup_intr).

Good news - this driver in -CURRENT!. Original patches used to add it to
-CURRENT are here. They should be 
applied in sequence.

  Log:
  Add snd_emu10kx driver for Creative SoundBlaster Live! and Audigy series
  sound cards with optional pseudo-multichannel playback.
  
  It's based on snd_emu10k1 sound driver. Single channel version is available
  from audio/emu10kx port since some time.
  
  The two new ALSA header files (GPLed), which contain Audigy 2 ("p16v") and
  Audigy 2 Value ("p17v") specific interfaces, are latest versions from ALSA
  Mercurial repository.
  
  This is not connected to the build yet.
