Jason A. Donenfeld ef8d6804d7 global: use netip where possible now
There are more places where we'll need to add it later, when Go 1.18
comes out with support for it in the "net" package. Also, allowedips
still uses slices internally, which might be suboptimal.

Jason A. Donenfeld fcc8ad05df netstack: further sequester with own go.mod and go.sum
In order to avoid even the flirtation with passing on these dependencies
to ordinary consumers of wireguard-go, this commit makes a new go.mod
that's entirely separate from the root one.

Jason A. Donenfeld 675955de5d tun: add tcpip stack tunnel abstraction
This allows people to initiate connections over WireGuard without any
underlying operating system support.

I'm not crazy about the trash it adds to go.sum, but the code this
actually adds to the binaries seems contained to the gvisor repo.

For the TCP/IP implementation, it uses gvisor. And it borrows some
internals from the Go standard library's resolver in order to bring Dial
and DialContext to tun_net, along with the LookupHost helper function.
This allows for things like HTTP2-over-TLS to work quite well:

    package main

    import (
        "io"
        "log"
        "net"
        "net/http"

        "golang.zx2c4.com/wireguard/device"
        "golang.zx2c4.com/wireguard/tun"
    )

    func main() {
        tun, tnet, err := tun.CreateNetTUN([]net.IP{net.ParseIP("192.168.4.29")}, []net.IP{net.ParseIP("8.8.8.8"), net.ParseIP("8.8.4.4")}, 1420)
        if err != nil {
            log.Panic(err)
        }
        dev := device.NewDevice(tun, &device.Logger{log.Default(), log.Default(), log.Default()})
        dev.IpcSet(`private_key=a8dac1d8a70a751f0f699fb14ba1cff7b79cf4fbd8f09f44c6e6a90d0369604f
    public_key=25123c5dcd3328ff645e4f2a3fce0d754400d3887a0cb7c56f0267e20fbf3c5b
    endpoint=163.172.161.0:12912
    allowed_ip=0.0.0.0/0
    `)
        dev.Up()

        client := http.Client{
            Transport: &http.Transport{
                DialContext: tnet.DialContext,
            },
        }
        resp, err := client.Get("https://www.zx2c4.com/ip")
        if err != nil {
            log.Panic(err)
        }
        body, err := io.ReadAll(resp.Body)
        if err != nil {
            log.Panic(err)
        }
        log.Println(string(body))
    }

Jason A. Donenfeld ea6c1cd7e6 device: receive: do not exit immediately on transient UDP receive errors
Some users report seeing lines like:

> Routine: receive incoming IPv4 - stopped

Popping up unexpectedly. Let's sleep and try again before failing, and
also log the error, and perhaps we'll eventually understand this
situation better in future versions.

Because we have to distinguish between the socket being closed
explicitly and whatever error this is, we bump the module to require Go
1.16.
