Add support to URLRequest for deferring redirects.

I chose to add an out parameter to OnReceivedRedirect because it allows for the
default behavior to remain the same.

I considered adding a ContinueAfterRedirect method that all OnReceivedRedirect
implementations would need to call, but this caused one annoying problem:  In
the case of a ChromePlugin, it is possible for the URLRequest to get deleted
inside the handler for the redirect.  This would make it hard to subsequently
call a method on the URLRequest since I would need to have a way to determine
if the URLRequest had been deleted.
