commit 8ed77b039fd0373fdc07ec79877caf34b8264cd2

    general-functions.pl: validdomainname misinterprets RFC1035
    
    The function validdomainname checks that each part of a domain name is at least
    2 characters in length, but RFC1035 only makes a restriction on a "label" being
    at most 63 characters in length. This change allows reverse DNS zones like
    2.168.192.in-addr.arpa to be added to the DNS forward configuration, which was
    incorrectly prevented before.
