proto.[hc]
    define new APIs to allow delayed registration of protocol fields,
	so that dissectors with "flexible" fields  like xml, radius, diameter,
	snmp do not have to load their files at startup but can do so as late as possible.

gtk/dfilter_expr_dlg.c :
	have the expression dialog registering all prefixes so that all fileds appear in the dialog

tshark.c
	register all prefixes when called with -G

epan/radius_dict.l
epan/dissectors/packet-radius.c
epan/dissectors/packet-radius.h
	refactor registration to delay dictionary loading as long as possible
