RouteAdd expects at least Dst.IP, Src, or Gw to be set, but accesses the
destination IP without testing for Dst being nil in the first place.

This provides the basic functionality of the iproute2 `route get`
command. It allows you to query netlink for the route to a destination
IP.Net
While implementing I noticed that the `s.Receive()` function was hanging
after the netlink response was recieved, so I added an additional clause
to break from the loop and return the decoded message if the NLM_F_MULTI
flag is not set.

Having object composition causes both client and library to
do potentially unecessary work to retrieve Link attributes
when only index is often sufficient.
