1b41de0653 - fixed the rate selection in the plug layer: 
the multiples of the given rate is chosen if available.
  the nearest rate is selected as usual if not available.

b9343e0834 - unified snd_pcm_hw_params_* functions 
- added backward compatibility for older non-compatible functions
- added --with-compat-rc3 to configure script to build library
  backwards compatible with 0.9.0rc3
- added symbol versioning like libc.so.6
  - ALSA_0.9      - alsa base
  - ALSA_0.9.0rc4 - first set of new functions (snd_pcm_hw_params_*)

b4b00dd7cf removed invalid assert().
