first fragment of a non-reassembled packet, and we know the length the packet would have if it were reassembled, this field holds the length of the fragment, and the "reported length" field shows the length the packet would have if it were reassembled, so going past the end of the fragment but staying within the length of the reassembled packet can be reported as "dissection would have worked if the packet had been reassembled" rather than "the packet is too short, so it was probably malformed". Add a FragmentBoundsError exception, thrown in the "dissection would have worked if the packet had been reassembled" case. Add a new tvb_new_subset_length_fragment() routine to create a new subset tvb with specified fragment and reported lengths. Use it in the CLNP dissector. Add some more sanity checks in the CLNP dissector. svn path=/trunk/; revision=48917
