361. [func] When the RBT find or chain functions set the name and

origin for a node that stores the root label
			the name is now set to an empty name, instead of ".",
			to simplify later use of the name and origin by
			dns_name_concatenate(), dns_name_totext() or
			dns_name_format().

 360.	[func]		dns_name_totext() and dns_name_format() now allow
			an empty name to be passed, which is formatted as "@".
