l2tp: use random Tunnel IDs
Re-use the Session ID selection algorithm for generating Tunnel IDs.
When a peer always uses the same source port for establishing tunnels,
and if ephemeral ports aren't activated (default), then Tunnel IDs are
the only way to identify tunnels. Using ramdom Tunnel IDs then
minimises the risk of re-using IDs of half-closed tunnels (i.e. tunnels
closed locally, but still existing on the peer side).
As a minor side effect, the maximum value of a Tunnel ID is now
2^16 - 1.
