From Lars Roland: add support for building a libethereal.dll with MSVC:

	add a config.nmake option to control whether to build
	libethereal.dll or not;

	remove "./wiretap" from PATH to prevent problems due to
	wrongly-loaded files;

	build dissector.lib with MSVC;

	move "print.c" and "ps.c" to the dissector helpers, as "print.c"
	imports variables from packet-frame.c and packet-data.c, which
	are in libethereal;

	move "g711.c" out of the dissector helpers, as they're used only
	by Ethereal in a tap, not in Tethereal or in any dissector;

	add a .def file for libethereal;

	arrange to declare global variables exported from libethereal
	with "__declspec(dllimport)" when building programs that import
	those variables;

	update the NSIS installer.

Make the "configure" script define ETH_VAR_IMPORT as "extern".
