[ fixes #53238 ] make this accept NULL's (and return FALSE for them).

2004-01-26  Chris Toshok  <toshok@ximian.com>

	[ fixes #53238 ]
	* util/eab-destination.c (nonempty): make this accept NULL's (and
	return FALSE for them).
	(eab_destination_is_empty): shorten some of the tests since
	nonempty takes NULL now.
	(eab_destination_get_address): only call
	camel_internet_address_add if both name and email are non-empty.
	otherwise call camel_address_decode and let camel try to deal with
	it.
	(eab_destination_xml_encode): call xmlEncodeEntitiesReentrant on
	the strings before adding them to the xml, so people that enter
	[<>&] won't end up with broken EABDestinations.
