Provide tvb_ensure_length_remaining(), which is like
tvb_length_remaining() except that it throws BoundsError if 'offset'
is out-of-bounds.
Allow a length argument of -1 for FT_STRING and FT_BYTES fields
in proto_tree_add_item().
Change some dissectors to either use -1 for the length argument in
calls to proto_tree_add_item(), or call tvb_ensure_length_remaining()
instead of tvb_length_remaining(), or to check the return-value
of tvb_length_remaining(). Changes to more dissectors are necessary,
but will follow later.
