music_pipe: added music_pipe_peek()
...
music_pipe_peek() is similar to music_pipe_shift(), but doesn't remove
the chunk. This allows it to be used with a "const" music_pipe.

pipe: added music_buffer, rewrite music_pipe
...
Turn the music_pipe into a simple music_chunk queue. The music_chunk
allocation code is moved to music_buffer, and is now managed with a
linked list instead of a ring buffer. Two separate music_pipe objects
are used by the decoder for the "current" and the "next" song, which
greatly simplifies the cross-fading code.

music_pipe: added music_pipe_push()
...
Added music_pipe_allocate(), music_pipe_push() and
music_pipe_cancel(). Those functions allow the caller (decoder thread
in this case) to do its own chunk management. The functions
music_pipe_flush() and music_pipe_tag() can now be removed.

music_chunk: added music_chunk_write(), music_chunk_expand()
...
Moved some code from music_pipe_write() and music_pipe_expand(). Only
music_chunk.c should access the music_chunk internals.

music_pipe: removed music_pipe_append()
...
The function is unused, since decoder_api() uses music_pipe_write() /
music_pipe_expand() now.

music_pipe: added functions music_pipe_write() and music_pipe_expand()
...
This new API gives the caller a writable buffer to the music pipe
chunk. This may allow the caller to eliminate several buffer copies,
because it may manipulate the returned buffer, until it calls
music_pipe_expand().

music_pipe: narrowed assertion on chunk index
...
The chunk index passed to successor() must be valid, i.e. it must be
smaller than num_chunks.

player: chop the tail of the music pipe after CANCEL
...
When a CANCEL command is received, the player should drop all chunks
of the next song. Added new funciton music_pipe_chop() which is used
for that.

music_pipe: continuously check the sample format of all chunks

Provide a debug function which asserts on the sample format of all
chunks. Call this function in each iteration of the player main loop.

music_pipe: check for partial frames in appended chunk

existing tail chunk.

music_pipe: add tag pointer to the music_chunk struct
...
Each music chunk can now carry a tag object. Decoder plugins which
support it (e.g. oggvorbis) may use this to inject decoded tags into
their output.

in the future.

decoder: replaced music_pipe.audioFormat with dc.out_audio_format
...
.. and rename dc.audioFormat to dc.in_audio_format. The music pipe
does not need to know the audio format, and its former "audioFormat"
property indicated the format of the most recently added chunk, which
might be confusing when you are reading the oldest chunks.

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.
