e35c674d13 alsa: limit buffer_size to 32768 frames.
In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory
allocation error on my system.

8bfd7f6a47 alsa: fallback to buffer_size/4 for period_size.
buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.

147bcf27c4 ALSA: implement channel layout for playback.
Currently quad, 5.0, 5.1 and 7.1 are implemented.
Implementing support for other formats/layouts and capture should be
straightforward.

5.0 and 7.1 support by Carl Eugen Hoyos.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

419bddd366 Include alsa headers before the internal FFmpeg headers.
This avoids symbol redefinitions problems, for example avoids the "free"
symbol to be redefined before system headers actually using it are
included, thus breaking compilation. In particular this change allows
to build FFmpeg with salsa.

bad5537e2c Use full internal pathname in doxygen @file directives.
Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
