Max Kellermann 767b4c95bd renamed outputBuffer.[ch] to pipe.[ch]
No CamelCase in the file name.  The output_buffer struct is going to
be renamed to music_pipe.  There are so many buffer levels in MPD, and
calling this one "output buffer" is wrong, because it's not the last
buffer before the music reaches the output devices.
