Add a dissector table for EAPOL Key Descriptor types.

Instead of having a switch statement in the EAPOL dissector for Key
Descriptor types, have a dissector table, and:

	have the EAPOL dissector register with a dissector for the RC4
	type;

	have the 802.11 dissector register with dissectors for WPA and
	RSN types.

This means that ieee_80211_add_tagged_parameters() no longer needs to be
public; make it static.
