395572e2f3 - Correctly increment the channel refcount in dsp_open() such that it is 
no longer possible to unload the driver module while sound is playing
  (which resulted in a panic).
- Fix a similar problem with the sndstat device that I found while looking
  at the above.
- Append a newline character to error messages in pcm_unregister()

5596676e6c KSE Milestone 2 
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

f53d43761e the feederchain builder is currently broken for recording channels. disable 
it until it is fixed.  this limits recording to native formats and speeds

2cfb90cc8d 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.
