.. and not the stack buffer.  This made the AllocatedString destructor
crash.

Closes #52

Was broken by commit 8a86460b

Closes #87

Addresses #82.

Previously, the ffmpeg decoder only checked for the "generic"
MusicBrainz metadata keys used in other metadata container formats.

We will reuse these tags elsewhere.

Enable it in the Windows build script, closes #78.

LAME currently doesn't support Android:

 checking host system type... Invalid configuration `arm-linux-androideabi': system `androideabi' not recognized

This commit is similar to 788e3b31,
and removes more "pure" attributes which were placed on functions that
could throw exceptions, which is illegal according to clang's
understanding of the attribute (but not according to GCC's).  GitHub
issue #58 was most likely about StorageDirectoryReader::GetInfo() and
Storage::GetInfo(), which still had "pure" attributes.

Closes #58

Add ffmpeg decoder support for *.adx files (Sega game console)

Closes #60

Patch from

(with a tiny modification)

Closes #59

Apparently, this makes old clang versions happy ("'alignas' attribute
cannot be applied to types).

Prepare for Mac OS X support by omitting those Ubuntu-specific
commands.

.. and not update-alternatives, which requires "sudo".

Fixes build failure on OS X, closes #44.  With the other plugins,
that's not critical, because those use the AudioOutputWrapper, which
hides this problem.

Closes #34
