Comment # 14 on bug 8111 from 
The ideas look good to me, but we can't rely on the protocol giving us the
total expected length before we get segments (DTLS does this, but not all
might).

There should likely be another check in fragment_set_tot_len that invalidates
existing fragments or throws a dissector bug or something if we try to set a
length while we already have fragments beyond it. This would also save us
having to care about the call order in the DTLS dissector.

Thoughts?
