748a830ba6 now we have the rate feeder, we don't need to constrain the default channel 
speed.  however, continue to do so for record channels until the feederchain
builder is fixed.

f53d43761e the feederchain builder is currently broken for recording channels. disable 
it until it is fixed.  this limits recording to native formats and speeds
only.

2cfb90cc8d many changes: 
* add new channels to the end of the list so channels used in order of
addition

* de-globalise definition of struct snddev_info and provide accessor
functions where necessary.

* move the $FreeBSD$ tag in each .c file into a macro and allow the
/dev/sndstat handler to display these when set to maximum verbosity to aid
debugging.

* allow each device to register its own sndstat handler to reduce the amount
of groping sndstat must do in foreign structs.

caf4a686e5 Use INTR_TYPE_AV for the interrupt handlers because: 
1: most drivers are sensitive to timing, and
2: the handlers are MPSAFE and need a chance to get into the kernel
before some other non-mpsafe handler blocks the ithread on Giant in
shared irq cases.

4a0664e88e use a global devclass for all drivers - i'm not entirely sure why this 
worked before.

mixer, dsp and sndstat are seperate devices - give them their own cdevsws
instead of demuxing requests sent to a single cdevsw.

use the si_drv1/si_drv2 fields in dev_t structures for holding information
specific to an open instance of mixer/dsp.

nuke /dev/{dsp,dspW,audio}[0-9]* links - this functionality is now provided
using cloning.

4b91e2ecf0 "Fix" the previous initial attempt at fixing TUNABLE_INT(). This time 
around, use a common function for looking up and extracting the tunables
from the kernel environment.  This saves duplicating the same function
over and over again.  This way typically has an overhead of 8 bytes + the
path string, versus about 26 bytes + the path string.

0732738ec4 Make the TUNABLE_*() macros look and behave more consistantly like the 
SYSCTL_*() macros.  TUNABLE_INT_DECL() was an odd name because it didn't
actually declare the int, which is what the name suggests it would do.

9c040b1c43 Move out the files from src/sys/isa/ic/ to src/sys/dev/ic/, so they 
can be made userland-visible as <dev/ic/...>.  Also, those files are
not supposed to contain any bus-specific details at all, so placing
them under .../isa/ has been a misnomer from the beginning.

The files in src/sys/dev/ic/ have been repo-copied from their old
location (this commit is a forced null commit there to record this
message).
