		Handling name collisions in the connection handler

Collision detection and prevention

	Before a node comes up on the network it listens to see who
	is already on the network by executing "connioctl listen;"

	after listening for a sufficient period of time (at LEAST 40 seconds)
	the node attempts to bring itself up on the network by executing
	a "connioctl enable" command;

	if another node already has the name that this node is attempting
	to use then the CONN_IOCENABLE fails and the connioctl program
	prints an error message without the node ever sending a packet
	on the network;

	if the node is enabled and a packet from another node with the same
	name is received then a message is printed on the console from
	within the kernel and the current node is disabled.  In this way
	either all nodes or all but one node with the same name will be
	disabled.

There should NEVER be more than one entry in the connection table for
a given name.  There may, however, be more than one entry for a particular
address.
