Cleanup: ResourceDispatcherHost::BeginDownload takes a scoped_ptr<URLRequest> argument.
This used to take an URLRequest*, with a comment about ownership. Changing to a scoped_ptr argument makes the ownership explicit and enforceable by the compiler.
Also, changed the name of the child_id argument to be process_unique_id to be consistent with the rest of the file.
