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.). Closes: https://github.com/alsa-project/alsa-lib/issues/431 Link: https://github.com/alsa-project/alsa-lib/pull/435 Signed-off-by: Jaroslav Kysela <perex@perex.cz>
