a3fd74d0dc doc: converted doc/COMMANDS to DocBook 
The goal is to have one structured document which is the authoritative
protocol specification.  The documentation which currently resides in
the wiki will be merged.

05f4629fa3 wavpack: redo using audio_format_frame_size() 
Somehow we lost 600e1322 after renaming some variables in ed6f6046.

362ca300d6 decoder: pass the correct buffer length to pcm_convert() 
When a global audio format is configured (setting
"audio_output_format"), decoder_data() overwrote the "length"
parameter with the size of the output buffer (result of
pcm_convert_size()).  Declare a separate variable for the output
buffer length.

33b5015469 ffmpeg: read tags from AVFormatContext 
The ffmpeg library provides some of the song metadata in the
AVFormatContext struct.  Pass it from there to MPD.

63272d6888 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.

7591403566 input_stream: size==-1 means unknown size 
Define the special value "-1" as "unknown size".  Previously, there
was no indicator for streams with unknown size, which might confuse
some decoders.

8882f06200 ffmpeg: fixed AVSEEK_SIZE 
With whence==AVSEEK_SIZE, the seek function should return the file
size, not the current offset.  Check the return value of
input_stream_seek().

9c4e97a61b aac: detect whether to pass "uint32_t*" to NeAACDecInit2() 
neaacdec.h declares all arguments as "unsigned long", but internally
expects uint32_t pointers.  This triggers gcc warnings on 64 bit
architectures.  To avoid that, make configure.ac detect whether we're
using Debian's corrected headers or the original libfaad headers.  In
any case, pass a pointer to an uint32_t, conditionally casted to
"unsigned long*".

acfba02310 decoder: check length==0 in decoder_read() 
When the caller passes length==0, decoder_read() entered an endless
loop.  Check that condition before entering the "while" loop.

00da7db1e3 aac: don't try to free static buffer 
In 432da18e a dynamic buffer was replaced by a static one but some
frees were accidently left there which caused some segfaults.

7720a1195a volume: eliminate alloca() usage 
alloca() is not a portable function.  Don't use it.  Using
strncasecmp() is much more efficient anyway, because no memory needs
to be allocated and copied.

eb199ca207 player: don't queue song when there are 2 songs in the pipe 
Don't send a "next song" request to the main thread when the current
song hasn't started playing yet, i.e. there are already two different
songs in the music pipe.  This would erase information about the song
boundary within the music pipe, and thus triggered an assertion
failure.  The bug could occur when playing very short songs which fit
into the pipe as a whole.

418dac6f94 player: wake up decoder before waiting for xfade chunks 
Fix a deadlock: when the decoder waited for buffer space, the player
could enter a deadlock situation because it waits for more chunks for
crossfading chunks.  Signal the decoder before entering notify_wait().

440b1ea3ea wavpack: be more robust if the underlying stream is not seekable 
The wavpack open function gives us an option called OPEN_STREAMING. This
provides more robust and error tolerant playback, but it automatically
disables seeking. (More exactly the wavpack lib will not return the
length information.) So, if the stream is already not seekable we can
use this option safely.

c495c6f5af wavpack: tolerate less decoded data than requested

decoded, rather it tries to go on.

7b7340f703 mp3: fix SEEK command check after mp3_synth_and_send() 
mp3 seeking was broken, because the command==SEEK check was never
reached.  Swap the command check order (==SEEK before !=NONE) to fix
that.

1a3945b563 decoder: check dc.command at the beginning of decoder_data() 
Seeking was somewhat broken in some decoder plugins because they sent
empty chunks, and never got a command.  Check the decoder command
before doing anything else in decoder_data().

709640422c 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.

eff21067f0 mpc: assume the result fo of mpc_decoder_decode() is unsigned 
According to the documentation, mpc_decoder_decode() returns an
mpc_uint32_t.  Since the special return value (mpc_uint32_t)-1
translates to a very large long integer, this may cause segmentation
faults if not interpreted properly.

975d5cd77e mpc: make the buffer large enough for one mpc frame 
Don't split the buffer conversion loop.  When libmpcdec returns a
chunk, convert and send the whole chunk at a time.  This moves several
checks out of the loop, and greatly improves performance.
