From bced8711f67b5dba76e9d6cdfd1a0246b235df27 Mon Sep 17 00:00:00 2001
From: Guy Harris <guy@alum.mit.edu>
Date: Mon, 3 Dec 2001 04:00:26 +0000
Subject: Make "dissector_add()", "dissector_delete()", and
 "dissector_change()" take a dissector handle as an argument, rather than a
 pointer to a dissector function and a protocol ID.  Associate dissector
 handles with dissector table entries.
