: External SFQ classifiers/flow classifier

These patches add support for external classifiers to SFQ and add a new "flow" classifier, which can do hashing based on user-specified keys or deterministic mapping of keys to classes. Additionally there is a patch to make the SFQ queues visisble as classes to verify that the hash is indeed doing something useful and a patch to consifiy struct tcf_ext_map, which I had queued in the same tree.

Please apply, thanks.
