- Use std::string, freebsd_nvlist_up to manage life cycle of class
members.
- Use an unordered_map<> keyed by std::string in struct conf to
replace the previous TAILQ.
- Replace PG_FILTER_* macros with a scoped enum.
- Provide a variety of accessors as portal groups are widely used
while keeping members private.
- The logic to "move" sockets from existing portals to new portals
when parsing new configuration is now split into several operations
across the conf and portal_group classes to preserve some semblance
of data hiding.
