libifconfig: multiple feature additions
Added the ability to: * Create virtual interfaces * Create vlan interfaces * Get interface fib * Get interface groups * Get interface status * Get nd6 info * Get media status * Get additional ifaddr info in a convenient struct * Get vhids * Get carp info * Get lagg and laggport status * Iterate over all interfaces and ifaddrs And add more examples, too. Note that this is a backwards-incompatible change. But that's ok, because it's a private library. MFC after: 3 weeks Sponsored by: Spectra Logic Corp Differential Revision: https://reviews.freebsd.org/D14463
