[webkit-dev] Database in Worker context

[Darin Adler]

My main feedback on this plan would be to land and review the work in pieces that are as small as possible.

For example, factoring out the database bits into a separate database manager class should be done in an initial first pass that does not make other changes.

I’m also not sure I like classes with Manager in their name, but I suppose we have a lot of such classes (controllers, managers, etc.) in WebKit already.
