asomers 0d688befe3 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.
