6221457152 move make_dev operations for audio channels to pcm_addchan(). in theory, 
with modifications to MAKEDEV this will allow use of multiple output streams
on cards supporting it, eg trident 4dwave.

1698a08e9a move channel-swapping support to the hardware driver since it knows the card 
state best

7de5d2d418 Update for pnp adjustments regarding NPNP. 
Also, optimize out a mess of #if's that were duplicating work already
done by config(8).  For example, if a file is marked as
"dev/sound/pci/foo.c optional pcm pci" then it's only added if pcm *and*
pci are present, so #if NPCM > 0 and #if NPCI > 0 are totally redundant.
A bit more work is still needed.

Discussed with: cg (a few weeks ago)

f1bbb0150a * add a non-reset device- will not reset the channel on open. you 
will have to mknod yourself for now.
* don't eat the first write()
* partial rvplayer fix- don't panic on unaligned writes unless our
  feeder chain requires them for downconversion.  a fuller fix is
  on the way.

e9e0512210 Remove five now unused fields from struct cdevsw. They should never 
have been there in the first place.  A GENERIC kernel shrinks almost 1k.

Add a slightly different safetybelt under nostop for tty drivers.

Add some missing FreeBSD tags
