- 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.
- Switch from the old 'log' class (ERR/DBG/etc) to a better
'logger' class. Also use LOG_* as defined in syslog.h.
- Make it possible to read debug messages even for release.
- Add a new argument (-v|--verbose) to 'ndppd' to change
verbosity level.
