[Serdev] Can the function is_to_local be added to the domain module

[Klaus Darilion]

There is a function to check for to-tags: has_totag()

I do it this way:

if (is_from_local() ) {
	#authenticate local user
	route(8);
} else {
	# request from non local user? is only allowed if loose routing is used 
and to tag is present
	if ( is_present_hf("Route") && has_totag() ) {
		xlog("L_INFO", "%is [%Tf]: %rm %fu -> %ru: relaying allowed because 
route header is present\n");
	} else {
		sl_send_reply("403", "we don't support relaying");
		xlog("L_ERR", "%is [%Tf]: %rm %fu -> %ru: 403 relaying not allowed 
->break\n");
		break;
	};
};
