3e27c54902 prepare for adding a rate conversion feeder. 
move format conversion feeders to feeder_fmt.c - no pertinent history so no

a6b7de97e3 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

ca84dc3f91 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.

cg
db66cff047 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.

cc65486f22 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.

b7b1206010 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.

7716c5370a 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

809e9b3b6c add module metadata. this is a hack, sound drivers will eventually present a 
bus to which pcm, mixer, etc will attach.

when playing, if we stall for 1s with no data advancing, abort and mark the
channel dead - fail all future operations

36c3965ff9 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.
