* Fix a bug where pollfds would be changed while in the poll_all
loop. This issue didn't exist before 'auto' was implemented.
* Fix so 'auto' rules won't try to forward Neighbor Solicitation
Packages through proxy's interface.
* Some code cleanup.
* Fix so that "route-ttl" in ndppd.conf works
* Fix a typo in ndppd.conf.5
* Update "ndppd.conf" to reflect the big changes
* Fix a bug with config loader
* Fix so that "auto" will never forward a Neighbor Solicitation
Message out through the "proxy" interface
- Bugfixes.
- New 'auto' configuration to be used in a 'rule' section. When using
this option, the routing table /proc/net/ipv6_route will be used to
auto-detect which interface to use when forwarding solicitation messages.
- New 'route' class to resolve which interface to query when using
'auto' configuration.
- Cleaned up the code some more.
