From 4d8d477018ac51a9536103e34368dc11a37e2ed4 Mon Sep 17 00:00:00 2001

Subject: Move create_tempfile() to tempfile.c out of util.c.  This means
 dumpcap no longer needs util.c, so it no longer includes routines that use
 host_ip_af(), so it no longer needs to define its own host_ip_af().

That also means dumpcap.c no longer needs to include <sys/socket.h>.
