4433248bf3 remove superfluous free() checks 
free() correctly handles NULL pointers, so we can omit explicit checks
for that condition.

33a40df1af Fix the handling of stereo capture source 
Patch from bug#1610

The simple mixer doesn't handle the stereo "Capture Source" properly,
wrongly set cswitch-joined.

a33c78ddd8 moved simple mixer abstraction modules to modules/mixer/simple directory 
Compile dynamic modules outside the alsa-lib tree to allow linking them
against libasound.so - proper versions of dynamic symbols.

59a8226184 The simple mixer abstraction - more work 
- separated the "base library" from ac97.c (dynamically loaded)
  - added necessary handling of all private structures
  - added selector and sid registration functions and handling code
- added basic code for hda.c (yeah, my notebook has this hw)

ce67d5389b more simple mixer - basic abstraction - work 
- midlayer cleanups and simplification
- probably broke the "none" abstraction code somehow (not intensively tested
  midlayer changes)
- trying to implement ac97 module
  - far from finished
  - common code should be moved to alsa-lib as core for other modules
  - perhaps simple_abst.c can be based on this common code, too

3bcf2f805d Implemented the top-level redirector code for simple mixer

- also fixed some error paths for name function

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

8336a94225 fixed handling of capture switch / volume: 
"Capture Switch" and "Capture Volume" controls are handled
capture switch and volume without playback capabilities.

capture switch and volume capabilities are not set on
global switches and volumes such as Bass and Treble.
only playback switch/volume is set.
