commit 15729bef385211bc2a0497e2d53a45c45d677d2c

BIO_lookup_ex: use AI_ADDRCONFIG only if explicit host name is given
The flag only affects which record types are queried via DNS (A or
AAAA, or both). When node is NULL and AF_UNSPEC is used, it prevents
getaddrinfo returning the right address associated with the loopback
interface.
