fd77c4000d Ensure all calls to getaddrinfo are headed by a block_dns check. 
If block_dns is set, call getaddrinfo with AI_NUMERICHOST set and
AI_CANONNAME clear.

Some paths may not have set AI_CANONNAME, but it's easier to audit
this way when the getaddrinfo prelude is uniform across call sites,
and the compiler can optimize it away.
