I.e., the moral equivalent of "ethertype()", but to allow arbitrary
dissectors to switch on TCP or UDP ports rather than on Ethernet type?

(BTW, that made me realize that I could probably just make "ethertype()"
associate a hash table with "eth.type"; other dissectors could register
Ethernet types with "eth.type", and it'd still work not only with
the type fields in Ethernet packets but also with the Ethernet type
field in an LLC/SNAP header and so on.)
