If UpdateStreamTag() gets called while an initial seek is pending, the
result will never be submitted to a MusicChunk.  By avoiding the
UpdateStreamTag() call in that case (by moving UpdateStreamTag() to
after the PrepareInitialSeek() check), the song_tag is preserved until
UpdateStreamTag() is called again from SubmitData().

This fixes missing tags in the "httpd" output.

We need this even when AFMT_S24_PACKED is not available, for the
correct channel order in multi-channel files.  Internally, MPD uses
FLAC channel order, but OSS uses the same channel order as ALSA.

This way, we save the overhead for acquiring the tag_pool_lock.

Also, use RemoveAll() instead of directly clearing TagBuilder::items in
most cases, as its elements represent references that must be released.

Closes #1023

This plugin has been defunct for several years.  Tidal has not ever
replied to any of my emails, so they're apparently not interested in
MPD support.

ProxyInputStream::Read() assigns the `offset` field, which is the
wrong offset because it does not consider Icy metadata removed from
the stream.  Therefore, after every ProxyInputStream::Read() call,
IcyInputStream::Read() needs to override this offset.  This was
missing at the end of the stream, when Read()==0.

this->OwnsTag() accesses fields that are not yet initialized.

Instead of checking for "cover.jpg" in the virtual directory
representing the CUE sheet, check its enclosing directory.

Updating the database no longer requires the `admin` permission, only
`control` is needed (changed in 2abad0f4).

The script seems to assume package version numbers always end in numeric versions with an optional alpha-suffix. Alas, were it only so simple... Sometimes the package is called fizzbang-1.2.3+release_info in which case the build fails. No more!

This fixes reading ID3 tags on remote files with the commands
"readcomments" and "readpicture".

Closes https://github.com/MusicPlayerDaemon/MPD/issues/1180

Make sure that ZeroconfDeinit() gets called even if startup fails with
an exception.  Fixes an assertion failure because an Avahi TimerEvent
is still active.

Closes https://github.com/MusicPlayerDaemon/MPD/issues/1192

Fixes the error:

 IllegalStateException: Not allowed to start service Intent { cmp=org.musicpd/.Main (has extras) }: app is in background

av_demuxer_iterate() was added in libavformat 58.9.100.

Closes https://github.com/MusicPlayerDaemon/MPD/issues/1178

Prevents a possible bug which occurs when the caller-provided open()
function throws; then the "uri" field is never set.

Prevent false negative after the stream was closed automatically after
20 seconds.

From libavformat/mov.c.

This mapping was added 11 years ago in commit 766b9fd4, but FFmpeg
doesn't appear to support it.

These were added 11 years ago in commit 766b9fd4, but I cannot find
any evidence in the FFmpeg repository that these names were ever
supported.  This commit adds the tags as they are currently present in
libavformat/mov.c.

When updating everything, this did work, but if updating only a
subdirectory, the ".mpdignore" in the parents were not used.

Closes https://github.com/MusicPlayerDaemon/MPD/issues/1172

Fixes broken libavahi-client timeouts.
