Clean up the BSD license to match the preferred license in
/usr/share/examples/etc/bsd-style-copyright. I've fixed a
few minor wording and formatting differences.

Approved by: luigi, Hannu Savolainen <hannu@opensound.com>

Start each of the license/copyright comments with /*-, minor shuffle of lines

fix whitespace bogons

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.

add support for opti924 and opti930 chips

both should work in non-pnp mode, the 924 should also work in its rather
braindead pnp mode- it will adopt port 0x530 unless given hints due to it
starting up in soundblaster mode and thus not requesting a valid mss port
address.

Supported the mss on PC-98 and Sound Blaster 98.

seperate the ad1816 driver from the mss driver since it shares no code

mss and sb drivers updated for newpcm

Reviewed by: peter, dfr

Bring in ad1816 patches from German Tischler.
Fix 'device not configured' problem that people were experiencing
when only PCI devices are present.

Update the pcm driver to the most recent version. This should
add support for Vibra16X, OPTi925, and bring in several assorted
fixes to the code and documentation.
Also present here are apm hooks so that laptops can properly
reconfigure the hardware after suspend (tested on the Libretto50).

This updates Luigi's sound code to the basic code in snd971023...
changes:
o rip the old select from his distribution to prevent extra pollution
o the code now uses audio dma, helps reduce clicks
o improved card support, should work in full duplex on sb16 cards
o add better voxware ioctl support pointed out by Joao Carlos Mendes
Luis <jonny@coppe.ufrj.br>
o remove an unused file that I included for more complete history
o and MANY other changes

I have personally tested this code with a CS4237 based card and an AWE32
(non-PnP). Both cards worked fine in 8bit and 16bit mode.

Import of Luigi Rizzo's sound code. For more information about the driver
check out the README that is included.
