Added DNS header mask definitions. Currently, we do a lot of data munging with manual hex. This is ugly and can lead to bugs. I defined the following: _QR_MASK 0x8000U _OP_MASK 0x7800U _AA_MASK 0x0400U _TC_MASK 0x0200U _RD_MASK 0x0100U _RA_MASK 0x0080U _Z_MASK 0x0040U _AD_MASK 0x0020U _CD_MASK 0x0010U _RCODE_MASK 0x000fU So that we can more easily twiddle flags. v2: make evdns flag masks unsigned literal Closes: #756 (cherry-picked)
