Anthony Coddington e2b0aa21ea ERF: Fix dissector abort on short meta tags and typos 
Fix dissector abort on short tags.
Fix value typo in hash mode enum.
Differentiate unexpectedly short value, zero length (deliberate invalid)
and off-end-of-record tags through expertinfo.
Continue to use proto_tree_add_*() length mismatch warnings for unxepectedly
long tags for now.
Change WWN tags to FT_BYTES for now as they are 16 not 8 byte WWN. Not
currently implemented outside Wireshark anyway.
