enum conf_port_type is local to conf.c and is used to track the port forwarding mode during configuration. We don't keep it around in the context structure, however the 'init_detect_ports' and 'ns_detect_ports' fields in the context are based solely on this. Rather than changing encoding, just include the forwarding mode into the context structure. Move the type definition to a new port_fwd.h, which is kind of trivial at the moment but will have more stuff later. While we're there, "conf_port_type" doesn't really convey that this enum is describing how port forwarding is configured. Rename it to port_fwd_mode. The variables (now fields) of this type also have mildly confusing names since it's not immediately obvious whether 'ns' and 'init' refer to the source or destination of the packets. Use "in" (host to guest / init to ns) and "out" (guest to host / ns to init) instead. This has the added bonus that we no longer have locals 'udp_init' and 'tcp_init' which shadow global functions. In addition, add a typedef 'port_fwd_map' for a bitmap of each port number, which is used in several places. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
