UDP and into the handoff registration routines for the protocols in

Make the dissectors for those protocols static if they're not called

Get rid of header files if all they did was declare dissectors that are
now static; remove declarations of now-static dissectors from header
files that do more than just declare the dissector.

Change to dns dissector to display "Domain Name System (request)" instead of
"DNS request" in the proto tree, as it is more in keeping with the style
of the other proto tree entries.
