char* srv_lookup	(	pool	p,
		const char *	service,
		const char *	domain
	)

do a DNS lookup

This function implements a SRV DNS lookup and falls back to normal AAAA/A resolution if no service has been given by the caller.

Parameters:

	p	memory pool to be used by this function
	service	which service should be looked up (e.g. "_xmpp-server._tcp")
	domain	which domain should be looked up

Returns:

comma separated list of results containing IPv4 and IPv6 addresses with or without ports

Todo:

The function honors the priority values of a SRV record but not the weight values. Implement handling of weights!
