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.).

resurrecting some decade old code I got some crashes and noticed a typo in
an old 0.9 legacy symver alias.
