Fix RFC6587 parsing on UDP.

My earlier fixes to UDP packet parsing broke RFC6587 parsing. By
eliminating use of the scanner (and thus the requirement that lines
should end with a \n character) I also removed the more functional
RFC6587 scanner which does not require a \n but does advance over
the length field. This patch restores use of the scanner where it
is explicitly specified (currently just RFC6587).
