Fixes several issues with header files:
- prefer alsa/asoundlib.h file for the alsa-lib core functionalities
(use #warning to inform current and future developers, do the job)
- include alsa/asoundlib.h in headers for external plugins by default
- pcm_external.h: dependencies cleanup
- as benefit, the parsers in IDEs should get all information for individial
header files (see PR#435)
This change was mainly tergetted to fix errors caused by wrong include order
(like for endianness detection, missing typedefs etc.).

The simpler mixer interface is not legacy, so the header file shouldn't claim
otherwise.

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.
- 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
- 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
the following functions are added:
int snd_mixer_selem_is_enumerated()
int snd_mixer_selem_get_enum_items()
int snd_mixer_selem_get_enum_item_name()
int snd_mixer_selem_get_enum_item()
int snd_mixer_selem_set_enum_item()
