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.)
