612276f48c do not blindly assume 8khz is supported on open(). try for 8khz but respect 
minspeed/maxspeed specified by the hw driver.

c9c6ba09e4 prepare for adding a rate conversion feeder. 
move format conversion feeders to feeder_fmt.c - no pertinent history so no
repo-copy.

33dbf14a17 change mixer api slightly 
change channel interface - kobj implementation coming soonish
make pcm_makelinks not panic if modular
add pcm_unregister()

these changes support newpcm kld unloading, but this is only implemented
by ds1.c

c07a337569 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.

7c438dbe9c 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.

513693be6c 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.

05a1fdb459 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.

fb0ef52838 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

f314f3dad2 add module metadata. this is a hack, sound drivers will eventually present a 
bus to which pcm, mixer, etc will attach.

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.
