Johny Mattsson f82415f6b9 Fix to do TCP port number randomization at boot.
This addresses the issue where a server would otherwise reject a valid
connection attempt from a rebooted node, due to the server thinking that
packet belonged to a recently closed session. By starting off the local
TCP port numbers at random* points each boot the risk of port reuse
across a reboot is significantly reduced.

*) As random as can be had via the lower 12 bits of the ccounter.
