Filtering duplicate addresses in listen (ticket #2400).
Due to the glibc bug[1], getaddrinfo("localhost") with AI_ADDRCONFIG
on a typical host with glibc and without IPv6 returns two 127.0.0.1
addresses, and therefore "listen localhost:80;" used to result in
"duplicate ... address and port pair" after 4f9b72a229c1.
Fix is to explicitly filter out duplicate addresses returned during
resolution of a name.
