zebra: labeled unicast handling
Support install of labeled-unicast routes by a client. This would be
BGP, in order to install routes corresponding to AFI/SAFI 1/4 (IPv4)
or 2/4 (IPv6). Convert labeled-unicast routes into label forwarding
entries (i.e., transit LSPs) when there is a static label binding.
