02185af5a9 Change the module name from 'snd_sonicvibes' to 'snd_vibes' as that is
the filename (thus the "old" module name) and the name used by
snd_driver.ko.

67b1dce3bc 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.

46700f1259 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.

d95502a838 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.

various locking fixes.

66ef8af5b0 mega-commit.
this introduces a new buffering mechanism which results in dramatic
simplification of the channel manager.

as several structures have changed, we take the opportunity to move their
definitions into the source files where they are used, make them private and
de-typedef them.

the sound drivers are updated to use snd_setup_intr instead of
bus_setup_intr, and to comply with the de-typedefed structures.

the ac97, mixer and channel layers have been updated with finegrained
locking, as have some drivers- not all though.  the rest will follow soon.

50aac86c8a Change type of channel speed variable from "int" to "u_int32_t" to
avoid overflow when scaling playback rate.  Fixes 44.1k playback from
being 48k (I am deaf to this difference...).
