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.

2dacd16b5b decoder: additional dc.command checks in decoder_data() 
When a command is sent while the decoder waits for a free chunk in the
music pipe, it was not returned by decoder_data().

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.

66ce1495f0 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.

998d9a8225 decoder: ignore SEEK commands during initialization 
When the decoder receives a SEEK during initialization, it should
ignore that for now.  The old code made most decoders abort.

df09075afc player: assert that there was no previous "next song chunk" 
When assigning the next_song_chunk variable, it must have been empty.
If not, there may be 3 songs overlapping in the music pipe.

ae9bb92952 playlist: call clearPlayerQueue() only if song is queued II 
This patch extends commit 35a16b99, and amends several 2 missing
checks.  It simplifies 2 more checks by merging "if" conditions.

b67a8e4d6e aac: shift the input buffer before the full check 
When the buffer was full, but everything was already consumed,
fillAacBuffer() would not attempt to flush and refill it.

487e05c67d aac: reject SEEK commands 
The aac plugin does not support seeking.  Reject SEEK requests by
calling decoder_seek_error().  Quit the plugin's main loop only when
STOP is received.

35a4ca2421 aac: convert audio_format to temporary variable 
The audio_format variable is only used and initialized for
decoder_initialized().  Move it into that block to save some bytes on
the stack.

39fa60769c aac: removed method file_decode() 
aac_stream_decode() was basically copy+pasted from aac_decode().
Since stream_decode() can also decode files, eliminate aac_decode().

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.

731e99c26e mpc: moved code to mpc_to_mpd_buffer() 
mpc_to_mpd_buffer() converts a whole chunk at a time.  This eliminates
3 local variables in mpc_decode().

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.

67814eddff mp3: support stream tags 
Parse ID3 tags, even when they are in the middle of the stream.  Very
few streams provide embedded ID3 tags.  Most of them send only
Shoutcast "icy" tags, which limits the practical usefulness of this
patch.

514c37b0cd mp3: eliminated duplicate command check 
When a command is received, decode_next_frame_header() and
decodeNextFrame() return DECODE_BREAK.  This is already checked by
both callers, which means that we can eliminate lots of
decoder_get_command() checks.

1bfa6a94e2 player: fix race condition during tag update 
When a tag is updated, the old tag was freed before the new one was
created.  Reverse the order to be sure that other threads always see a
valid pointer.

This still leaves a possible race condition, but it will be addressed
later.

acf0d141be playlist: track song metadata changes 
When the tag of the current song changes (e.g. a new tag was sent in
the stream), update the playlist, so clients pick up the new tag.

9eed41911f decoder: return void from decode() methods 
The stream_decode() and file_decode() methods returned a boolean,
indicating whether they were able to decode the song.  This is
redundant, since we already know that: if decoder_initialized() has
been called (and dc.state==DECODE), the plugin succeeded.  Change both
methods to return void.

8a40e0b495 replay_gain: use pcm_volume() to apply replay gain 
The currently replay_gain_apply() implementation duplicates code from
pcm_volume(), except that it uses a floating point scale.  Eliminate
all duplicated code from and make it utilize the pcm_volume() library
function.  This introduces replay gain support for 24 bit audio.

edcd45df94 pcm_volume: added constant PCM_VOLUME_1 
It may be desirable to change the range of integer volume levels
(e.g. to 1024, which may utilize shifts instead of expensive integer
divisions).  Introduce the constant PCM_VOLUME_1 which describes the
integer value for "100% volume".  This is currently 1000.
