Michael Mann 2eb7b05b8c Convert most UDP dissectors to use "auto" preferences. 
Similar to the "tcp.port" changes in I99604f95d426ad345f4b494598d94178b886eb67,
convert dissectors that use "udp.port".

More cleanup done on dissectors that use both TCP and UDP dissector
tables, so that less preference callbacks exist.
