New features:

-- Support for runtime cpu detection
-- Stand alone compile of libaf
-- Unlimited number of channels (compiletime switch)
-- Sample format defined by bit-fields
-- New formats: float, A-Law and mu-law
-- Format conversion set in human readable format
   i.e. format=4:us_be to set 32 bit unsigned big endian output
-- Format reporting in human readable format
-- Volume control has only one parameter for setting the volume
   i.e. volume=-10.0:1:0:1 to set atenuation = -10dB
