There is only a single user who needs it to be reentrant (not really,
but it's safer like this), add rt_addr_n2a_r() for it to use.

There are only three users which require it to be reentrant, the rest is
fine without. Instead, provide a reentrant format_host_r() for users
which need it.

Currently ip6 encap support for lwtunnel is missing.
This patch implement it, mostly duplicating the ipv4 parts.
Also be sure to insert a space after the encap type, when
showing lwtunnel, to avoid the tunnel type and the following
argument being merged into a single word.

Currently parse_encap_ip() does not update correctly argv/argc;
if multiple lwtunnel arguments are provided, the parsing fails after
the first one, i.e.
ip route add 172.16.101.0/24 dev vxlan1 encap ip id 42 dst 192.168.255.1
fails with:
Error: either "to" is duplicate, or "dst" is a garbage.
This commit addresses the issue, stepping to next argument at each iteration
of the parsing loop.

This patch:
- Adds a utility function for parsing a 64 bit address
- Adds a utility function for converting a 64 bit address to ASCII
- Adds and ILA encap type in lwt tunnels

This patch adds support to parse and print lwtunnel
encapsulation attributes attached to routes for MPLS
and IP tunnels.
example:
Add ipv4 route with mpls encap attributes:
Examples:
MPLS:
$ ip route add 40.1.2.0/30 encap mpls 200 via inet 40.1.1.1 dev eth3
$ ip route show
40.1.2.0/30 encap mpls 200 via 40.1.1.1 dev eth3
Add ipv4 multipath route with mpls encap attributes:
$ ip route add 10.1.1.0/30 nexthop encap mpls 200 via 10.1.1.1 dev eth0 \
nexthop encap mpls 700 via 40.1.1.2 dev eth3
$ ip route show
10.1.1.0/30
nexthop encap mpls 200 via 10.1.1.1 dev eth0 weight 1
nexthop encap mpls 700 via 40.1.1.2 dev eth3 weight 1
IP:
$ ip route add 10.1.1.1/24 encap ip id 200 dst 20.1.1.1 dev vxlan0
