a6295c60ae when setting blocksize, fix blockcount to 2 to reduce latency with smaller 
block sizes.

fca71897c4 don't enable the mic record channel unless the codec supports it. 
allow hardware buffer size to be specified using hints.

a67fe5c1d6 change tracking of channel counts. 
add method for retrieving "buffersize" hints for pcm devices, adjusted for
specified minimum, maximum and default values.

a3a1ce3024 add a tunable/sysctl, hw.snd.targetirqrate, to modify the default target 
irq rate for apps that do not set a blocksize.

5c25132af5 - 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()

b40ce4165d 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!)

4f4449e01c now we have the rate feeder, we don't need to constrain the default channel 
speed.  however, continue to do so for record channels until the feederchain
builder is fixed.

4132a3b206 the feederchain builder is currently broken for recording channels. disable 
it until it is fixed.  this limits recording to native formats and speeds
only.

67b1dce3bc 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.

19f2be11b0 Limit the device to only one playback channel until I can figure out why 
a) newpcm insists on using only the highest number channel available, and
b) the maestro3 driver no longer likes anything above channel 0.

f637a36cfd don't flag the playback hardchan as busy on devices with only one of them. 
if a device has vchans already but they are all busy, allocate another one

when creating/destroying vchans, don't make/remove a devnode for the
first/last one as it replaces a hardchan.
