Merge of r4654, r4672, r4684, r4685, r4692: resolver changes.
*) Resolver: fixed format specification.
Patch by Yichun Zhang (agentzh).
*) Support for IPv6 literals and an optional port in resolver.
*) Fixed crash in ngx_resolver_cleanup_tree().
If sending a DNS request fails with an error (e.g., when mistakenly
trying to send it to a local IP broadcast), such a request is not
deleted if there are clients waiting on it. However, it was still
erroneously removed from the queue. Later ngx_resolver_cleanup_tree()
attempted to remove it from the queue again that resulted in a NULL
pointer dereference.
*) When "resolver" is configured with a domain name, only the first
resolved address was used. Now all addresses will be used.
*) Fixed segfault with poll and resolver used.
Poll event method needs ngx_cycle->files to work, and use of
ngx_exit_cycle without files set caused null pointer dereference in
resolver's cleanup on udp socket close.
