Please don't use errorCallback/SuccessCallback. That's not used in any
other APIs that are part of the cross-browser web platform. Instead
return a request object on which events are fired.

Don't use enums as the syntax sucks in JS. Use strings instead. We're
making the same transition in a lot of other APIs.

There's also a problem in that Gecko treats IndexedDB as permanent
quota by default and Chrome treats it as temporary. Not sure how to
solve that problem.

You guys have this prefixed in your implementation for now, right?
