  ofproto-dpif-xlate: add uuid to xports

This should make possible to look up xport by UUID and will be used by a
later commit.

  xlate: fix xport lookup for recirc

Xlate_lookup and xlate_lookup_ofproto_() provides in_port and ofproto
based on xport determined using flow, which is extracted from packet.
The lookup can happen due to recirculation as well. It can happen, that
packet_type has been modified during xlate before recirculation is
triggered, so the lookup fails or delivers wrong xport.
This can be worked around by propagating xport to ctx->xin after the very
first lookup and store it in frozen state of the recirculation.
So, when lookup is performed due to recirculation, the xport can be
retrieved from the frozen state.

The packet-type-aware unit tests are updated with a new one to verify
this behavior.
