Paul Marks 676550d040 net: use dialTCP cancelation for DualStack dialing.
The previous Happy Eyeballs implementation would intentionally leak
connections, because dialTCP could not be reliably terminated upon
losing the race.

Now that dialTCP supports cancelation (plan9 excluded), dialParallel can
wait for responses from both the primary and fallback racers, strictly
before returning control to the caller.

In dial_test.go, we no longer need Sleep to avoid leaks.
Also, fix a typo in the Benchmark IPv4 address.

Updates #11225
Fixes #14279

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.

Go is the work of hundreds of contributors. We appreciate your help!

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
