Convert IEEE802.11 tagged fields into a dissector table

One GIANT switch statement is a little difficult to maintain, so convert each
case into its own function and add them to a dissector table.  Many of the
case statements were already their own function, but signatures needed to
be converted into dissector_handle_t
-1 was uses as the protocol for the dissector handles because there isn't
a need to be associated with a protocol.  This also allows third-parties
and plugins to add tagged fields outside of Wireshark using the new
dissector table.
