Refactor IDB factory creation

[Brady Eidson]

Refactor how IDB databases get their disk locations

Contrary to a comment and unused static variable, IDBFactoryBackends are not global singletons.  They have a 1:1 relationship with IDBFactory.

And it doesn't make sense to have one factory support databases in different locations on disk.

So this patch moves the directory argument from IDBDatabaseBackend to IDBFactoryBackend.

It also adds the top-level security origin as an argument into database opening, as that should further differentiate the uniqueness of a database in the future.

[Brady Eidson]

Retitling to Refactor IDB factory creation:

-Rework directory location
-Make (some) SecurityOrigin arguments be references instead of pointers
-Add two SecurityOrigin arguments to opening databases for future use

Is this being used somewhere?

Probably not, leaked through from a separate patch.  Thanks for catching it.

Fixed locally.

We should pass the WebIDBFactoryBackend by reference here, since null is not a valid input.
