aea0875b7b do not blindly assume 8khz is supported on open(). try for 8khz but respect 
minspeed/maxspeed specified by the hw driver.

b47aafbd4d make the test for hwptr going backwards more picky- now it only triggers if 
15/16 of the buffer is skipped or we go backwards by < 1/16 of buffer size.

7ec6797b5b add devfs support. when devfs is enabled, sysctl hw.sndunit is used to set 
which sound unit the /dev/{dsp,mixer,dspW,audio} links point at.  this can
also be set from the loader.

9aa3234516 rework feeder sytem to allow feeders in klds 
modify driver capability reporting format to list every audio format
seperately- required for above and because we could not previously indicate
that mono was unsupported.

there should be no functional impact.

02c322a0a4 Simplex devices will always report EBUSY on 2nd (and subsequent) 
opens if the reference count is not decremented on close.

Note that this may result in the reference count being corrupted
on full duplex devices (due to mismatching opens/closes), but the
code doesn't use the reference count for anything on full duplex
devices.

4b24af17f5 Finally merge newmidi. 
(I had been busy for my own research activity until the last weekend)

Supported devices:

SB Midi Port			(sbc + midi)
SB OPL3				(sbc + midi)
16550 UART			(midi, needs a trick in your hint)
CS461x Midi Port		(csa + midi)

OSS-compatible sequencer	(seq)

Supported playing software:

playmidi			(We definitely need more)

Notes:

/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).

EMU8000(SB AWE) does not sound yet but does get probed so that the OPL3
synth on an AWE card works.

TODO:

MSS/PCI bridge drivers
Midi-tty interface to support general serial devices

633deb3a69 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.
