9626b608de Separate the struct bio related stuff out of <sys/buf.h> into 
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" 
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

7207eca657 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.

c2af6f650c 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)

62c631ed7f * Ignore the wierd fakechan workarounds for simplex in dsp_ioctl(). 
Without this, ioctl commands for setting formats and speeds were
  essentially ignored for simplex devices until the application actually
  performed a read or write.
* Make sure that both channels are set in the SB mixer code and provide a
  mixer table specifically for the ess18xx which supports the extended
  accuracy available on this part.
* Fix a stupid bug in ess_format() which ignored the passed-in format and
  changed the hardware based on the value which was set last time. This
  meant that the hardware setting was often not set correctly at all.
* Add a custom identify driver for the ESS1888 which automagically detects
  and adds the device in a pseudo-PnP way. This driver also emits the magic
  sequence which enables the sound hardware after a hard reset, allowing
  it to work correctly for the sound hardware of a PWS 433au (and probably
  all other PWS class alpha machines).

With these changes, I was able to play back simple sounds on my 433au. I
have not tested recording or any other formats other than 8bit ulaw and
16bit stereo.
