Angus Gratton a75ca8a1c0 esp32/modsocket: Use all supplied arguments to socket.getaddrinfo().

- Completes a longstanding TODO in the code, to not ignore
  the optional family, type, proto and flags arguments to
  socket.getaddrinfo().

- Note that passing family=socket.AF_INET6 will now cause queries
  to fail (OSError -202). Previously this argument was ignored so
  IPV4 results were returned instead.

- Optional 'type' argument is now always copied into the result. If not
  set, results have type SOCK_STREAM.

- Fixes inconsistency where previously querying mDNS local suffix (.local)
  hostnames returned results with socket type 0 (invalid), but all other
  queries returned results with socket type SOCK_STREAM (regardless of
  'type' argument).

- Optional proto argument is now returned in the result tuple, if supplied.

- Optional flags argument is now passed through to lwIP. lwIP has handling
  for AI_NUMERICHOST, AI_V4MAPPED, AI_PASSIVE (untested, constants for
  these are not currently exposed in the esp32 socket module).

- Also fixes a possible memory leak in an obscure code path
  (lwip_getaddrinfo apparently sometimes returns a result structure with
  address "0.0.0.0" instead of failing, and this structure would have been
  leaked.)
