I disagree with "fixing" the ID3v2FrameFactory issue. It's a singleton
that never gets more than one instance. I'll have a look at the ASF
changes. Thank you.

In general, the patches don't follow the TagLib coding style (no tabs,
2 spaces, no space after if/for), so have to be reformatted.

I'll not merge this one, see https://github.com/taglib/taglib/pull/12
for the reason.

I'm not sure about this, the debug messages are meant to be debug
messages, not general-purpose error messages displayed to the user.
