519474451a all: make copyright headers consistent with one space after period
This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.

Go policy has been single space after periods in comments for some time.

The copyright header template at:

    https://golang.org/doc/contribute.html#copyright

also uses a single space.

Make them all consistent.

24a83d3545 net: add Dialer.Cancel to cancel pending dials
Dialer.Cancel is a new optional <-chan struct{} channel whose closure
indicates that the dial should be canceled. It is compatible with the
x/net/context and http.Request.Cancel types.

Tested by hand with:

package main

    import (
            "log"
            "net"
            "time"
    )

    func main() {
            log.Printf("start.")
            var d net.Dialer
            cancel := make(chan struct{})
            time.AfterFunc(2*time.Second, func() {
                    log.Printf("timeout firing")
                    close(cancel)
            })
            d.Cancel = cancel
            c, err := d.Dial("tcp", "192.168.0.1:22")
            if err != nil {
                    log.Print(err)
                    return
            }
            log.Fatalf("unexpected connect: %v", c)
    }

Which says:

    2015/12/14 22:24:58 start.
    2015/12/14 22:25:00 timeout firing
    2015/12/14 22:25:00 dial tcp 192.168.0.1:22: operation was canceled

Fixes #11225

a5dec3859a net: make multi-IP resolution more flexible.
Remove the "netaddr" type, which ambiguously represented either one
address, or a list of addresses. Instead, use "addrList" wherever
multiple addresses are supported.

The "first" method returns the first address matching some condition
(e.g. "is it IPv4?"), primarily to support legacy code that can't handle
multiple addresses.

The "partition" method splits an addrList into two categories, as
defined by some strategy function. This is useful for implementing
Happy Eyeballs, and similar two-channel algorithms.

Finally, internetAddrList (formerly resolveInternetAddr) no longer
mangles the ordering defined by getaddrinfo. In the future, this may
be used by a sequential Dial implementation.

Updates #8453, #8455.

29d1f3b85c net: add socket system call hooks for testing
This change adds socket system call hooks to existing test cases for
simulating a bit complicated network conditions to help making timeout
and dual IP stack test cases work more properly in followup changes.

Also test cases print debugging information in non-short mode like the
following:

Leaked goroutines:
net.TestWriteTimeout.func2(0xc20802a5a0, 0xc20801d000, 0x1000, 0x1000, 0xc2081d2ae0)

	/go/src/net/server_test.go:398 +0x667
