  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)
