Implement IndexedDatabase::open up until re-entrance into WebKit. That (and the

rest of IndexedDB) will be done in subsequent patches.  Included in this patch
is a lot of other infrastructure for making IndexedDB work.  Included is a
conversion from the DOMStorageDispatcherHost into a dispatcher host for all APIs
that have a backend in WebKit.

I named it WebKitAPIDispatcherHost.  Since it's in browser/in_process_webkit and
it is for APIs that connect up to the WebKit API and it's used for APIs whose
backend is implemented in WebKit I thought the name was decent and not _too_
confusing, but if you have better ideas, please let me know.

This includes some code that you've already reviewed (darin), but a lot has
changed so please take a look at all of it.

TEST=Not much to test yet + behind a flag.
BUG=none
