Log:
 Add to tvbuffs a "fragment length" field; if the tvbuff represents the
 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.
