[idn] hostnames

[Mark.Andrews@nominum.com]

	* The syntax of hostnames is defined in RFC 952.
	* RFC 103[45] does NOT define hostname syntax.
	* domain names labels are *binary* length tagged strings.
	* host names are restricted to 'A'-'Z' 'a'-'z' '0'-'9' '-' and '.'

	A lot of drafts keep miss using the term domain name when
	they actually mean host name based on the context.
