Ole Troan 18327be5d4 nat: 1:1 policy NAT 
A NAT sub-plugin doing statically configured match/rewrite on IP4 input or output.
It's stateless (no connection tracking).
Currently it supports rewriting of SA, DA and TCP/UDP ports.
It should be simple to add new rewrites if required.

API:
pnat_binding_add, pnat_binding_del, pnat_bindings_get, pnat_interfaces_get

CLI:
set pnat translation interface <name> match <5-tuple> rewrite <5-tuple> {in|out} [del]
show pnat translations
show pnat interfaces

Trying a new C based unit testing scheme. Where the graph node is tested
in isolation. See pnat/pnat_test.c.
Also added new cmake targets to generate coverage directly.
E.g.:
make test_pnat-ccov-report
