previously, dns_name_fromtext() took both a target name and an optional target buffer parameter, which could override the name's dedicated buffer. this interface is unnecessarily complex. we now have two functions, dns_name_fromtext() to convert text into a dns_name that has a dedicated buffer, and dns_name_wirefromtext() to convert text into uncompressed DNS wire format and append it to a target buffer. in cases where it really is necessary to have both, we can use dns_name_fromtext() to load the dns_name, then dns_name_towire() to append the wire format to the target buffer.
