Now that "bytes consumed" can be determined, should tcp_dissect_pdus() take advantage of that? Should tcp_dissect_pdus return length (bytes consumed)? There are many dissectors that just call tcp_dissect_pdus() then return tvb_length(tvb). Seems like that could all be rolled into one. svn path=/trunk/; revision=53198
