8d1ffb1684 mpc: get decoder command from decoder_data()
Removed 3 superfluous decoder_get_command() invocations.

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.

1414a3de4c mpc: declare buffer as int32_t[]
The buffer is always casted to int32_t* anyway; declare it as int32_t
array, and remove the cast.

06c60888dc mpc: eliminated the local variable "eof"
Since each "eof=true" is followed by "break", the variable is
superfluous.

401e77b258 decoder: fixed typo in assertion

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.

5e686add91 wavpack: added wavpack_tag_float()
The function simplifies wavpack_replaygain(), because it already
contains the float parser, and it works with a fixed buffer instead of
doing expensive heap allocations.

130659e856 decoder: fixed assertion failure for decoder==NULL in decoder_read()
The assertion on dc.state in decoder_read() was too strict: when a
decoder tried to call decoder_read() from tag_dup(), the decoder state
was NONE.  Allow this special case.

ff1acefb21 decoder: removed plugin method try_decode()
Instead of having a seprate try_decode() method, let the

to decode the song.

23a4ce4444 flac: call flac_process_metadata() for ogg files
The flac plugin wasn't initialized properly when an OGG file was being
decoded.  For some reason, flac_process_metadata() was explicitly not
called for OGG files.  Since that seems to fix the issue, make it
always call flac_process_metadata().

0e87f85598 flac: enable the oggflac plugin with older libflac versions
Since decoder_list.c does not include the libflac headers, it cannot
know whether to add the oggflac plugin to the decoder list.  Solve
this by always enabling the oggflac sub-plugin, even with older
libflac versions.  When the libflac API cannot support oggflac,
disable the plugin at runtime by returning "false" from its init()
method.

505959f74d flac: enable oggflac with libflac
The "oggflac" plugin was enabled only if HAVE_FLAC_COMMON was
defined.  HAVE_FLAC_COMMON however is only an automake variable, and
is never available in decoder_list.c.  Make decoder_list.c depend on
HAVE_FLAC||HAVE_OGGFLAC instead.

ab24e203cd wavpack: removed try_decode() method
Wavpack's try_decode() implementation does nothing useful, it only
duplicates code already in stream_decode() / file_decode(), and slows
down MPD.

72eba30cf4 decoder: converted dc.error to a dc.state value
The player did not care about the exact error value, it only checked
whether an error has occured.  This could fit well into
decoder_control.state - introduce a new state "DECODE_STATE_ERROR".

3e338da871 wavpack: check last_byte in push_back_byte() method
At this moment the wavpack lib doesn't use the return value of the
push_back function, which has an equivalent meaning of the return
value of ungetc().  This is a lucky situation, because so far it
simply returned with 1 as a hard coded value.  From now on the
function will return EOF on error.  (This function makes exactly one
byte pushable back.)
