util: retry getaddrinfo if getting EAI_BADFLAGS with AI_V4MAPPED
The FreeBSD header files define the AI_V4MAPPED but its
implementation of getaddrinfo() always returns an error
when that flag is set. eg
address resolution failed for localhost:9000: Invalid value for ai_flags
There are also reports of the same problem on OS-X 10.6
Since AI_V4MAPPED is not critical functionality, if we
get an EAI_BADFLAGS error then just retry without the
AI_V4MAPPED flag set. Use a static var to cache this
status so we don't have to retry on every single call.
Also remove its use from the test suite since it serves
no useful purpose there.
