Add check to make sure that pcvm nodes are used as edge nodes only

(only 1 lan/link connection). An interim solution until we solve the
routing problem for "virtual" router nodes completely. Also added a
new global "enforce_user_restrictions" that you can set in your .ns
file to turn of this check, and some others.
