9ec437a334 add reinit functions to mixers 
unstaticize chn_start()
add reset/resetdone functions to channels

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

306f91b60b detach support

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.

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.

e4d5b2502d fix a bug where opening for write would not fail if channel allocation failed 
when playing, if we stall for 1s with no data advancing, abort and mark the
channel dead - fail all future operations

603ddb6d5d make mmap sort-of work. there seem to be interactions with certain hw 
drivers, so still work in progress.

do various mmap-related ioctls right.

improve blocksize control.

bits of cleanup.

7c7f2a4a81 make poll() dtrt, previously when playing it would trigger if there was less 
than 1 byte ready to play instead of room for at least 1 byte to be written.
similarly for recording.

d8b47cbb70 Stop isadma from abusing the B_READ, B_RAW and B_WRITE flags. 
Define ISADMA_{READ,WRITE,RAW} macros with the same numeric
values as the B_{READ,WRITE,RAW} and use them instead throughout.

f2410ff244 kludge to fix the end-of-sample repeating bug. i don't know why it happens; 
none of my hw does it, but this should fix it for now.

2abc85f0c0 argh, forgot the bus_dma_tag_creates. 
also, panic if channel init fails instead of derefing null.

98d83734f4 this is a full fix for writes not aligned to the sample size selected. 
should be a no-op in most cases.

5b78a73443 * 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.

to compile successfully.  further details will be provided in the commit
enabling newpcm.
