Redo the way selecting the mode for SB cards is done completely.
...
It is now table driven since there are so many different variations
of SB cards out there.
Also fix a bug that stopped SB2 and SBPro from working.

Redo the SB mixer code. The driver can now distinguish between the
...
four different mixer options: none, CT1335, CT1345, and CT1745.
It should now be possible to access most of the SB16 functionality.

Change the interface between high and lowlevel audio drivers again:
...
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.

Change the interface between the high and low level audio drivers
...
so that all audio encoding parameters are set at once. This simplifies
the interface and make error checking easier.

add MediaVision Jazz16 chipset support. It must be configured with
...
'flags 1' on the sb? kernel configuration file line (because it frobs a
noncontiguous IO port to configure the Jazz16 extensions).
Also, remove static sb_device structure and fill in user's buffer on
each request.
