Previously part of "Add packet recirculation" (v18)

v6
* Add tests for write_actions, mod_nw_{tos,src,dst}
* Rebase

v5
* No change

v4
* Remove test for recirculation of packet_out with in_port=CONTROLLER
  - This requires infrastructure or a workaround
    the details of which are under discussion.
* Remove spurious unrelated changes (miss-squash)
* Expect in_port=LOCAL for packet_in messages that
  result from a packet_out message.
  This is for compatibility with
  "[PACKET_OUT v2] ofproto-dpif: treat non-datapath ports as local port
   for OFPT_PACKET_OUT"

v3
* Rebase
* Remove misplaced and now unnecessary change in ofproto/
* Remove patch port tests
  - Support for this has been dropped
* Test multiple recirculations with packet_out

v2
* Use OVS_APP_EXIT_AND_WAIT(ovs-ofctl)
* Add resubmit and goto_table tests
* Clean up documentation of MPLS unicast and multicast types in packet descriptions
* Exercise recirculation of ARP
* Patch port and packet out tests
