ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Thu Jun 30 16:20:09 2022 +0200| [c9b6fd27bfbd2c4c99c1af8e86b70eeb47991124] | committer: Anton Khirnov

lavu/fifo: add the header to its own doxy group

Also, drop mentions of it being a circular buffer, as this is an
internal implementation detail that should be invisible to the caller.
