svn verify: use a custom editor and get_revision() Previously, we would fetch each file in the revision/changeset individually. With this change, we fetch the entire revision in one request, and use a custom editor to verify its contents. This is quite a lot faster than the previous means when verifying over the internet. By an order of magnitude or two, in fact. As data is transfered in a single operation, verifying a revision from PyPy took 30 seconds rather than 30 minutes, and saturated my 10Mbps connection. Please note that the output ordering isn't stable between the two; output will appear in reverse order when using the fast verifier.
