8d6838450a alsa-lib: Don't call the simple mixer interface "legacy" 
The simpler mixer interface is not legacy, so the header file shouldn't claim
otherwise.

Fixes bug#3569

68e5771a6f Remove assert from header files 
Putting assert in the public macros isn't good idea at all.
Let's get rid of them.

Also, clean up snd*_alloca() functions to use a helper macro
instead of copy and paste.

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

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
