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.
