When MPD was paused, and the client sent the "stop" command (or
"clear"), a glitch caused MPD to continue playback for a split second.
This was because audio_output_all_cancel() calls
audio_output_all_update(), which reopens all output devices, and
re-ignites the playback loop.
When decoding a local file, the decoder thread tries to run all
matching decoders, until one succeeds. Both file_decode() and
stream_decode() can decode a stream, but MPD closes the stream before
calling file_decode(). Problem is: when this decoder fails, and the
next's stream_decode() method is invoked, the input_stream is still
closed. This patch reopens it.
Several users had problems with binding MPD to "localhost". The cause
was duplicate /etc/hosts entries: the resolver library returns
127.0.0.1 twice, and of course, MPD attempts to bind to "both" of
them. This patch makes failures non-fatal, given that at least one
address was bound successfully. This is a workaround; users should
rather fix their /etc/hosts file.
When client_defer_output() aborts the connection to the client,
client_write_output() called client_write_deferred() anyway. This
caused an assertion failure. Fix it by checking for the "expired"
flag again after client_defer_output() returns.
When the decoder is finished, break out of the player loop only after
another player.pipe check. We did check the pipe size a few lines
above, but that check was kind of racy.
When a music_chunk only contains a tag but no PCM data, play_chunk()
returns true without freeing the chunk. The caller now assumes that
the chunk is moved into some music_pipe and does not bother to free it
either.
To check for leaked music_chunk objects, free the music buffer on
CLOSE_AUDIO. This invokes an assertion check which ensures that all
chunks have been returned to the buffer.
Instead of returning the local variable "ret" which is always true at
this point, hard-code the "true" return value, because that might be
more readable.
If a file is removed the library, next time mpd will try to play it it
will result in an error 'ERROR: problems decoding some/file.ogg'.

Commit f78cddb4 introduced a regression: when the playlist reached its
end, MPD did not reset the "current song" pointer anymore after stop.
Add a "current = -1" code line.
The only pc_seek() caller clears the error, rendering the check
useless. Even if the previous PLAY command resulted in a player
error, this check is not very useful.
Flush the encoder before calling encoder_tag(). The first page
generated by the encoder after sending the tag will be the new
"header" page, which is sent to all HTTP clients when they connect.
This is a little bit specific to the vorbis encoder, but there are no
other encoders which support tags (yet).
When a new tag is set, end the current stream and begin a new one.
Use vorbis_analysis_headerout() to write a full ogg header. This
fixes a problem with icecast: after a song change in MPD, icecast
stops forwarding ogg packets to its clients.
When a song was in the database twice (which shouldn't happen), and
the first song had no tag items, MPD calledd tag_free(NULL). Add a
check to that source location, and an assertion to tag_free().
