This patch series removes three more indirect calls from
the state_afinfo struct:
- extract_input (no dependencies on other modules)
- output_finish (same)
- extract_output (has dependency on ipv6 module, but
that is only needed for pmtu detection, so the indirect
call cost is not required for each packet).
Note that the 4th patch conflicts with Sabrinas ESP-in-TCP patches
(both change ipv6_stubs).
I will send a rebased v2 once those patches are in.
