Add the long-awaited check for nodes that have too many lans/links. For

now it is just hardcoded to 4, but could be done from the db too. Gives
errors like this one, from a topo where node2 and node6 each have 5 links:

*** /usr/testbed/devel/newbold/lib/ns2ir/parse.tcl:
    Too many links/LANs to node node2! Maximum is 4.
*** /usr/testbed/devel/newbold/lib/ns2ir/parse.tcl:
    Too many links/LANs to node node6! Maximum is 4.
*** /usr/testbed/devel/newbold/bin/batchexp:
    NS Parse failed!
