Loop over all frames with a specific id, and import all of them - not
just the first one (index 0).

this is inconsistent with other commands (e.g. find) and seems wrong --
a song with no stickers attached is a perfectly valid state and an empty
list of stickers is also perfectly valid.

One APE tag may contain more than one value, separated by null bytes.

Based on the APE reader.

Generic library for scanning APE tags.  Eliminated one "goto"!

Fixes a regression: for output_plugin.delay(), we added a method to
the timer class which returns the delay in milliseconds.  This fails
to detect negative values, because the unsigned integer is divided by
1000, and then casted to signed.

After popular demand, I've switched the order of "artist" and "title"
in the stream title.  There is no standard, and there is no reliable
way to parse those from the stream title.

Call access() and print an extra error message when EACCES is
returned.  Hopefully this will reduce the number of support requests
due to wrong file permissions.

The assertion added in MPD 0.15.14 was too much, it failed when the
MIME type of a stream was NULL.

When one song is played twice, and the decoder is working on the
second "instance", but the first should be seeked, the check in
player_seek_decoder() may assume that it can reuse the decoder without
exchanging pipes.  The last thing was the mistake: the pipe pointer
was different, which led to an assertion failure.  This patch adds
another check which exchanges the player pipe.

More abstraction for decoder_control.pipe.

Some abstraction for decoder_control.pipe access.

Duplicate the "mime" attribute of the inner input_stream object,
instead of copying the pointer.

This makes the plugin more responsive to control commands, because it
will listen to control events while waiting.

This method is used to reduce the delay of commands issued to the
shout plugin.

Same as ".m4a".

Change the assertion on "fail_timer==NULL" in OPEN to a runtime check.
This assertion crashed when the output thread failed while the player
thread was calling audio_output_open().

Protect the attributes "open" and "fail_timer".

Protect the attributes "open" and "fail_timer".

When you pass the flag AI_ADDRCONFIG to getaddrinfo(), it does not
consider address families on the loopback device.  When run on a
machine without an external network card, just with "lo", it was
unable to look up any address.

libffado documentation says this function returns -1 on error, but
that is a lie - it returns a boolean value, and "false" means error.
