51e4196f16 Handle running out of buffer space with IPv6 mapping enabled.
With big DNS answers like the one you get for goodtimesdot.com you can
get a truncated address list if IPv6 mapping is enabled.  Instead tell
the caller to resize the buffer.

75ded9bcdf Initialize local variable in resolver.
When the DNS server doesn't reply at all we possibly tested
an unitialized variable.

1c0ab5bd34 Handle overly large answer buffers in resolver.
In EDNS0 records the maximum result size is transmitted in a 16
bit value.  Large buffer sizes were handled incorrectly by using
only the low 16 bits.  Fix this by limiting the size to 0xffff.

44d20bca52 Implement second fallback mode for DNS requests.
There is some more shardware/software out there which has problems
if two DNS requests are sent using the same tuple

  (source addr, source port, dest addr, dest port)

This can range from firewalls to load balancers.  Some of the vendors
already fixed it in response to this problem.  Still, we need a way
to make glibc work with broken environments.  The single-request-reopen
flag can be used or we fall back automatically to this mode.

310647e980 Remember we switched to single-request mode.
This change prevents repetition in most later calls of the resolver
in case the DNS server or the network connection is broken.
