That attribute was uninitialized before, which could crash
libavformat.

See Debian bug 760669

See code comment.  Fixes assertion failure in
decoder_command_finished().

Log call was added to the wrong branch.

Fixes regression by commit ca1a1149

Casting std::numeric_limits<unsigned>::max() to "long" leads to an
overflow if sizeof(unsigned)==sizeof(long), and the result will be -1.

This happens on some 32 bit architectures, for example ARM and WIN32.

Workaround: use std::numeric_limits<int>::max(), which is the largest
signed integer.  Since sizeof(long)>=sizeof(int), this will never
overflow.

Fixes Mantis ticket 0004080.

- Rebuilt with new audiofile

The "current" attribute is a "song order", not a "song position".
This is usually the same - except in random mode.  Fixes Mantis ticket
0004073.

Fix incorrect description of the "songs" field and add missing
"albums" field.

The unit of gme_info_t::length is milliseconds, not centiseconds.

The previous commit was broken.  D'oh!

The IsActive() method returned true even if the timer was not active,
after it completed once.  This broke the state file timer, and the
state file was not saved periodically.

Same bug as in the previous commit.

When the data chunk size is not a multiple of the frame size, the last
partial frame lead to an endless loop.  We fix this by checking
chunk_sze>=frame instead of chunk_sze>0.  This way, the partial frame
is simply skipped.

According to POSIX and both OSX and Linux manpages,
strcasecmp comes from strings.h, not string.h.

Most OSes also have them available in string.h,
but we just fixed the headers on Haiku and it now
only provides them in strings.h.

We might want to fall back to string.h for other
OSes though...

In version 11, both ffmpeg and libav deprecate
AVCodecContext::codec_name.  The function avcodec_descriptor_get() has
been introduced long ago.
