Fix handling of OFPP_ANY in OpenFlow 1.1 and later.

Fix handling of OFPP_ANY in OpenFlow 1.1 and later.

Add OFPP_ANY to include/openflow/openflow-1.1.h, and allow it as a port in
queue stats request. Make ovs_ofctl use OFPP_ANY instead of OFPP_ALL for queue
stats requests on OF 1.1+.

This patch changes "none" ports print out. "none" is still accepted on input
for backwards compatibility, but it prints out as "ANY". To make this less
confusing, I changed the test cases to use "controller" or "any" instead of
"none". The test case that tests for both "none" and "controller" still tests
for them.
