Oct 21, 2024, modify dnsmasq

Too many DNS requests cause network congestion
new dnsmasq support min-cache-ttl
block dns type 65 which is for HTTPS
check dnsmasq Makefile and patches , download the xz from origin, find "if (qtype == T_SOA && option_bool(OPT_FILTER))"
change to "if ((qtype == T_SOA || qtype == 65) && option_bool(OPT_FILTER))" \

git diff src/rfc1035.c.bak src/rfc1035.c.mod > right.patch
calculate the offset
for 2.90, change the offset from 2143 to 2211, because the origin patches add total 68 lines don't edit the patch file with sublime
