3092edabf2 Propagate pcm->info 
Propate pcm->info bit flags from the slave PCM in refine.
This will fix the bug indicating bogus pause/resume capabilities.

b579a024db Add verbose hw_params debugging 
Added the verbose hw_params dump for debugging.
The verbose error message is shown with the current hw_params dump
when $LIBASOUND_DEBUG is set.

c67584ec65 Clear sw_params struct at initialization 
Do zero-clear the sw_params struct in hw_params, just to be sure.
This makes valgrind happy.

af89cefd99 More changes for dmix plugin: 
- added poll_events to main pcm structure
  - added poll_revents callback to pcm->ops structure
  - fixed snd_pcm_wait() - call revents function and enhanced
    error code reporting
DMIX plugin:
  - more complete code (works at least for one instance)
  - still no "mix" code (it's silent)

3b6638e8ce More pcm params functions returns an error rather than do assert().

Improved dmix refine method.

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(). 
there are reserved fields for the extended masks which are not used,
and this caused wrong assert()...
