[keyed_ipv6_tunnel] Fix regression introduced by #293 URGENT
[lib/nfv] selftest.sh: Added timeout to `wait_vm_up'.
[core.app/core.lib] Moved `equal' from `core.app' to `core.lib'.
[unified conf] Replace all uses of `dofile' and `loadstring' with the
central `core.lib.load_conf' and `core.lib.load_string'.

Provide central `lib.load_conf' and `lib.store_conf' to read and write
config files and use `store_conf' to generate zone configurations in
`designs/neutron/neutron2snabb'.

Replace leftover string app args with table literals.
