net: add sequential and RFC 6555-compliant TCP dialing. dialSerial connects to a list of addresses in sequence. If a timeout is specified, then each address gets an equal fraction of the remaining time, with a magic constant (2 seconds) to prevent "dial a million addresses" from allotting zero time to each. Normally, net.Dial passes the DNS stub resolver's output to dialSerial. If an error occurs (like destination/port unreachable), it quickly skips to the next address, but a blackhole in the network will cause the connection to hang until the timeout elapses. This is how UNIXy clients traditionally behave, and is usually sufficient for non-broken networks. The DualStack flag enables dialParallel, which implements Happy Eyeballs by racing two dialSerial goroutines, giving the preferred family a head start (300ms by default). This allows clients to avoid long timeouts when the network blackholes IPv4 xor IPv6.

net: fix parsing literal IP addresses in local database This change fixes incorrect parsing of literal IP addresses in local database when the addresses contain IPv6 zone identifiers, are in dotted-decimal notation or in colon-hexadecimal notation with leading zeros. https://golang.org/cl/5851 already fixed the code path using getaddrinfo via cgo. This change fixes the remaining non-cgo code path. Fixes #8243. Fixes #8996.
