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

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

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
