list_remove

	status.i4.v = list_remove(remove_node.s.r)

	This routine removes a node from a linked list.  After the node
	is removed, its "next" and "prev" pointers are invalidated so all
	ties to the list are lost.

	This function returns ACNET status values as follows:

	OK			node was successfully removed
	CLIB_NOW_EMPTY		node was successfully removed and the list
				is completely empty
	CLIB_NODAT		list specified is empty

	This function requires the following include files:

	cbslib_h, acnet_errors_h
