Hartmut Brandt 8e9b3e7071 Update bsnmp to version 1.13. This does not bring user-visible changes.
For developers gensnmptree can now generate functions for enums to convert
between enums and strings and to check the validity of a value.
The sources in FreeBSD are now in sync with the upstream which allows to
bring in IPv6 modifications.
