Removed virtual from several methods in DecoderDatabase to minimize
the number of points that need to be mocked for testing.

For the now non-virtual methods, DecoderDatabase now does a lookup
through GetDecoderInfo and then delegates to the appropriate method in
the DecoderInfo object, if one is found.

A few other methods were also changed to look up through GetDecoderInfo.

Also moved the audio decoder factory into DecoderInfo, so that
DecoderInfo::GetDecoder can be used directly.
