Paul Marks dcc905ecf9 net: compute the Dialer deadline exactly once.
When dialing with a relative Timeout instead of an absolute Deadline,
the deadline function only makes sense if called before doing any
time-consuming work.

This change calls deadline exactly once, storing the result until the
Dial operation completes.  The partialDeadline implementation is
reverted to the following patch set 3:
https://go-review.googlesource.com/#/c/8768/3..4/src/net/dial.go

Otherwise, when dialing a name with multiple IP addresses, or when DNS
is slow, the recomputed deadline causes the total Timeout to exceed that
requested by the user.

Fixes #11796

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.
