Commit Message

* Drop route command (use just ip command), support both IPv4 and IPv6
* Add route-lib.sh (will be used in other route-change-*)
* Use unused network range to avoid clash with real network
* Add verification with ping (previous version sent UDP datagram with
ns-udpsender, but didn't verify receiving it on rhost and didn't setup
rhost ip at all)

Just a small change, not worth of sending v2: use .sh extension
for all 3 tests (route-change-{dst,gw,if}.sh).

Kind regards,
Petr
