A bit of automake magic (see info automake "Per-Object Flags").

When a music_chunk to be crossfaded consists only of a tag,
cross-fading is not possible, and led to an assertion failure.  This
patch just discards those, as if cross-fading was not enabled.

During the whole output thread, the audio_output object is locked, and
it is only unlocked while waiting for the GCond and while running a
plugin method.  The error handler in ao_play_chunk() attempted to lock
the object again, which was code from MPD 0.15.x which should have
been removed a long time ago.

Until the decoder plugin has called decoder_initialized(), the player
may not submit seek commands.  This however could occur with a slow
decoder and a CUE file with a virtual song offset.  This patch adds
another check.

When you don't explicitly set an output sample rate, liblame tries to
guess an output sample rate from the input sample rate.  You would
think that this "guessing" consists of just setting both equal, but
that is not the case.  For 44.1kHz at 96kbit/s, liblame chooses
32kHz.  This patch explicitly configures the output sample rate, to
stop the bad guessing.

This is a MPD 0.16 regression: when playing a 24 bit file, the switch
to 16 bit was made only partially, after mBytesPerPacket and
mBytesPerFrame had already been applied.

That means mBytesPerFrame referred to 24 bit, and mBitsPerChannel
referred to 16 bits.  Of course, that cannot work.

Use "printf" instead.

Fixes autotools warnings.

It is known to crash instantly.

Cast the constant to dev_t, not to unsigned.

Fixes the gcc warning "implicit declaration of function 'htons'".

Rename the "version" struct, because it seems to be a reserved name on
Solaris:

 "src/decoder/mad_decoder_plugin.c", line 550: (enum) tag redeclared: version
 cc: acomp failed for src/decoder/mad_decoder_plugin.c

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.
