[ovs-dev] [PATCH 0/3] ofproto/trace: Add support for tracing conntrack recirc

This patch series enhances the usability of ofproto/trace when a flow
hit conntrack actions that involves recirculation. Instead of asking
users to run ofproto/trace multiple times to derive the final datapath
actions, we keep track of the conntrack actions, and automatically run
the recirculation process so that a user only need to execute the
ofproto/trace command once. A new option --ct-next is added for
ofproto/trace to customize the next ct_state during the trace.

v1 -> v2
- Move ct_state parsing to lib/flow.c instead of lib/conntrack.c
- Address various reviewer comments such as ref counting balance, code
structure, and typo fixes.

  conntrack: Move ct_state parsing to lib/flow.c
  ofproto/trace: Add support for tracing conntrack recirculation
  ofproto/trace: Add --ct-next option to ofproto/trace
