2124df1390 decoder: rewind input stream after try_decode()
The try_decode() method may have read some data from the stream, which
is now lost.  To make this data available to other methods, get it
back by rewinding the input stream after each try_decode() invocation.

The ogg and wavpack plugins did this manually and inconsistently; this
code can now be removed.

5183d85886 player: send chunk tag to audio device
If a chunk contains a tag, send it to the audio output device.  Few
output plugins support this, e.g. shout has support for sending tags.

aa9b31f1cf crossfade: copy tag
If the source chunk has a tag, merge it into the destination chunk.
The source chunk gets deleted after that, and this is our last chance
to grab the tag.

0f80428fda ffmpeg: use decoder_read() wrapper instead of direct input_stream_read()

4d069b4991 ogg, ffmpeg: try to decode, even when the stream is not seekable
Ogg and ffmpeg detection was disabled when the stream was not
seekable, because the detection was too expensive.  Since the curl
input stream can now rewind the stream cheaply, we can re-enable
detection on streams.

460b15d29c input_curl: buffered rewinding
During codec detection, the beginning of the stream is consumed.  This
is a common operation, which takes a lot of time when handling remote
resources.  To optimize this, remember the first 64 kB of a stream.
This way, we can rewind the stream without actually fetching the start
of the stream again.

c9e15bc418 decoder_api: pass "seekable" flag to decoder_initialized()

8b1f6ff3c8 decoder: replaced music_pipe.audioFormat with dc.out_audio_format
.. and rename dc.audioFormat to dc.in_audio_format.  The music pipe

property indicated the format of the most recently added chunk, which

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.
