- changed lowlevel drivers to use pcm_misc.c functions
- fixed some bugs in pcm_plugin_build
- the plugin code is shared between alsa-lib and alsa-driver

Rate plugin is now ready for optimizations (I've verified reading asm
generated that loop unrolling is not fully satisfactory, I'll try
another solution later today).

Bug fixed:
- duplicated deallocation for mmap'ed area
- missing deallocation in es18xx
- some bugs in volbal conversion
New features:
- virtual mixer for card-share (it seems to work, but I feel that it
need further testing)
Misc:
- reorganization and extension of rate.c
Jaroslav changes:
- volbal source is mostly reverted back (no card-share mixer polling)

Included in this message, you will find a diff to alsa-lib, which
implements g721 adpcm codec. It works well (only consumes a lot of CPU),
and it plays back the same data as is recorded.
Also added is CSP patch, which adds noise suppression when CSP is
started or stopped (A few TODOs less :) Also changed is copyright for
mulaw, alaw and adpcm codecs (Based on sun implementation ... + I added
myself - if you don't mind. Please check this copyright, if it is OK)

OK, the attached is the patch to alsa-driver and alsa-lib.
It will really violate the source/binary compatibility as
I wrote :-p
It includes:
- change of event data for accessing Timer Port
- new middle-level functions for sequencer in alsa-lib
- some comments / fixes
The test programs in alsa-lib (playmidi1, aconnect, aseqnet)
were rewritten to use the new functions above.
I included also a patch to pmidi-1.2.2.
