	basesrc/lib/libc/net: getaddrinfo.c

Log Message:
- do not make query for AFs that are not supported by kernel.
  i.e. do not make query for IPv6 addresses, when running on non-IPv6 kernel,
  or, do not query for IPv4 address on IPv6-only kernel :-)

  This kind of behavior is not very well documented in RFC2553.  This
  may violate the spec.

- on EAI_AGAIN, only retry 3 times (3 is a magic number).  Previous code
  made retries forever.  This solves situation where name server is wrongly
  configured and nameserver:53 returns icmp port unreach.

The only proper fix for all getaddrinfo() related twists would be to
implement getipnodebyname() and get rid of wacky get_addr().
We need to contribute bind8 development for this.
