This patch adds RVA2 (relative volume adjustment) tag
support to mpd, as a fallback if no replaygain tags are
found. The code is almost directly from madplay (GPL).
RVA2 tags are generated for example by the "normalize" utility.

The input_stream object should only be closed by the MPD core
(i.e. decoder_thread.c / decoder_run()). A decoder plugin which
attempts to close it will result in a segmentation fault.
Don't split configure options and their implementation. Check for the
backend library before the AM_CONDITIONAL, otherwise Makefile.am will
compile the plugin although the library may not be available.
When save_absolute_paths_in_playlists was enabled in mpd.conf, MPD
broke all playlists when manipulated using the "playlistdelete"
command. The reason was that map_directory_child_fs() was used, which
doesn't accept slashes in the file name. Use the new map_uri_fs()
function instead.
With a large maximum playlist length, the integer multiplication
"playlist_max_length * MPD_PATH_MAX" may overflow. Change that to a
division. This was not a dangerous bug, since it was only used for
a quick estimate.
It is illegal to pass an empty audio buffer around. pcm_resample()
sometimes seems to result in 0 samples, maybe related to
libsamplerate. To work around that problem, add special checks after
both pcm_convert() invocations. Removed the pcm_resample()==0 checks
from pcm_convert().
When a response is very long (e.g. a large playlist > 100k songs),
most of it will end up in the deferred buffers. Filling the deferred
queue is very expensive currently, because a new buffer is allocated
for every client_write() operation. This may lead to long delays, and
the client might give up and disconnect meanwhile. This patch makes
MPD attempt to flush the deferred queue as often as possible, to work
around this problem. Due to the MPD 0.14 code freeze, we should not
optimize the buffering code now.
Over time mpdconf has evolved and has been maintained and contributed to by many different folks at different
times. Try to give it some unity. Attempt to clear up some language and make things crystal clear. Add more
examples. Use tabs when it makes sense. Make better borders. Remove obsolete options. Try to put more defaults
when it makes sense.
