7fe9764 by Guy Harris (guy@xxxxxxxxxxxx):

    Make the TTL field unsigned, but keep warning if the high-order bit is set.
    
    See RFC 2181, section 8 (and RFC 1035 erratum 2130, which notes that
    section 3.2.1 says the TTL is signed but section 4.1.3 says it's
    unsigned); RFC 2181 section 8 says "unsigned, but avoid sending values
    that have the uppermost bit set, and treat values with the uppermost bit
    set as a value of 0".  (STD 13 = RFC 1034, the "concepts and facilities"
    DNS RFC, plus RFC 1035, the "implementation and specification" DNS RFC.)
