bb15c3bd45 mod: always initialize libmikmod
The "mod" decoder plugin was being initialized lazily, but was
deinitialized unconditionally.  That led to segmentation faults.
Convert mod_initMikMod() to be the global module initialization
method.  The MPD core should care about lazy initialization.

e5137706d1 ffmpeg: fix boolean inversion in ffmpeg_tag()
ffmpeg_tag() deleted the tag when ffmpeg_helper() returned success.
The return value was interpreted incorrectly, it should return the tag
on success.

accc82cd6c ffmpeg: don't rewind stream in url_close()
Rewinding the stream here is not useful, but may consume valuable
resources (and time).

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.

0f80428fda ffmpeg: use decoder_read() wrapper instead of direct input_stream_read()
decoder_read() checks the decoder command.  Without this patch, the
ffmpeg plugin could become unresponsive.

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.

3f6fcfd38e aac, mod: don't check for SEEK command
Since the aac and mod plugins have told MPD that they cannot seek, MPD
will never send a SEEK command to them.  Removed the SEEK comand
checks from both plugins.

c9e15bc418 decoder_api: pass "seekable" flag to decoder_initialized()
Don't pass the "seekable" flag with every decoder_data() invocation.
Since that flag won't change within the file, it is enough to pass it
to decoder_initialized() once per file.

ea515494cb added prefix to header macros
"LOG_H" is a macro which is also used by ffmpeg/log.h.  This is
ffmpeg's fault, because short macros should be reserved for
applications, but since it's always a good idea to choose prefixed
macro names, even for applications, we are going to do that in MPD.

8f37f7c838 ogg: don't include _flac_common.h

_flac_common.h, but including it leads to compiler errors when libflac

b15c4cdeb5 ffmpeg: use return value of decoder_data()

5f6383d68c mpc: provide 24 bit samples
Similar to libmad, libmpcdec provides samples with higher quality than
16 bit.  Send 24 bit samples to MPD, which allows MPD to apply
dithering just in case the output devices are only 16 bit capable.

d29bad4410 mp3: make mp3_read() return bool
Its only caller in mp3_decode() just compared its value with
DECODE_BREAK.  Convert that to bool, and return false if the loop
should be ended.  Also eliminate some superfluous command checking
code, which was already done in the preceding while loop.

528b7c3f5e decoder: automatically flush the output buffer after decoder exits
A decoder_flush() invocation was missing in the FLAC plugin, resulting
in casual assertion failures due to a wrong assumption about the last
chunk's audio format.  It's much easier to remove that decoder_flush()
function and make the decoder thread call ob_flush().

d6c4441c78 mp3: seek in background
Remember the seek_where argument and call decoder_command_finished()
immediately.  This way, the player thread can continue working, and we
can receive more commands.

This also fixes several issues which resulted in broken frames,
leading to erroneos "elapsed" values: frames weren't parsed properly,
since the code was checking for command!=NONE.
