Disable IndexedDB permissions check from workers

I left the rest of the code for 2 reasons:
1) To prevent it from not compiling.
2) To preserve the diff when I update it.

I foresee a quite skeptical webkit reviewer.

david, you had mentioned an invalid cast in the shared worker case... is this it on line 165?

[Michael Nordman]

maybe test if isSharedWorkerContext() and only short circuit that case to not regress for dedicated workers

Changed to only disable the test for shared workers.

Yes, this is the cast that needs to be changed to a WebWorkerBase.

Tony, could you review this?

Can you write a LayoutTest for this?

The behavior that's changing here (for shared workers) can't be tested with the current DRT because it doesn't run multiple processes.  I think a layout test for the dedicated worker case is possible, though it would involve changing layoutTestController.  Which I don't want to do right now on account of expediency.  (The only reason we're adding this bypass is to get the feature in front of developers ASAP.)

Though I've been meaning to add a permissions test for a while.  Bug filed at http://crbug.com/113738.  Is that ok?

Please mention this in the ChangeLog (e.g., No new tests because ....).

Having a bug for this is fine for now.  I would have filed it in webkit, but whatever works for you.
