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)

19811bb9b4 Changed data type of alsa-lib handles from 'void *' to the specific type for
the handle in use. This should be more type-safe as the compiler will perform
checking on type now.
