[NET]: Enhanced version of net_random().

Here is another alternative, using tansworthe generator.  It uses percpu
state. The one small semantic change is the net_srandom() only affects
the current cpu's seed.  The problem was that having it change all cpu's
seed would mean adding locking and the only user's today are a couple of
places that feed in mac address to try make sure address resolution to
collide.
