597b4d0942 big simple mixer update 
- exported all necessary functions to create a mixer module outside alsa-lib
- separated simple mixer API from the simple mixer implementation
  (using callbacks as usuall)
  - src/mixer/simple.c is the core
  - src/mixer/simple_none.c is the current (no-abstraction) implementation
    based on control names; note that this module does not depend on
    internal ALSA structures now
  - src/mixer/simple_abst.c is the ongoing abstraction which will use
    external dynamic modules; src/conf/smixer.conf will describe which
    modules will be used depending on the components from the driver

4d7c53d280 Add snd_pcm_hw_params_get/set_export_buffer() 
Add snd_pcm_hw_params_get/set_export_buffer() API functions.
They control to ensure the buffer export to other processes.
If this flag is set, the local buffer of a plugin is exported over IPC shm.
Otherwise the buffer can be handled only locally (no shm).

Also fixed Version file for 1.0.9.

5227c7e170 Fix possible noises and optimization with dmix 
dmix transfers data in asynchronously so that it doesn't write on the
last active period.  This will allow the arbitrary buffer size in
future, too.

The hwsync call to slave is removed from commit and hwsync callbacks.
This hack was added to fix the noisy output (typically on xmms/bmp)
but it doesn't happen any more.  Now the hwsync behavior is as same as
on 1.0.8 (i.e. hwsync is called only when slowptr option is set).
