This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

The macOS client was forgetting to call netstack.Impl.SetLocalBackend.
Change the API so that it can't be started without one, eliminating this
class of bug. Then update all the callers.

This is temporary while we work to upstream performance work in
https://github.com/WireGuard/wireguard-go/pull/64. A replace directive
is less ideal as it breaks dependent code without duplication of the
directive.

This allows tsnet services to make requests to other services in the
tailnet with the tsnet service identity instead of the identity of the
host machine. This also enables tsnet services to make requests to other
tailnet services without having to have the host machine join the
tailnet.

Before this would silently fail if this program was running on a machine
that was not already running Tailscale. This patch changes the WhoIs
call to use the tsnet.Server LocalClient instead of the global tailscale
LocalClient.

Allow callers to verify that a net.Listener is a tsnet.listener by type
asserting against this Server method, as well as providing access to the
underlying Server.
This is initially being added to support the caddy integration in

... so callers can provide the AuthKey via mechanisms other than
environment variables which means multiple Servers can't be started
concurrently in the same process without coordination.

Use the "tailscaled" prefix instead of "tsnet" for state file names:
1. It is consistent with the pre-existing {{Dir}}/tailscaled.state file.
2. It makes the file layout of `tsnet` and `tailscaled` identical,
so that they are compatible with each other.

This change wires netstack with a hook for traffic coming from the host
into the tun, allowing interception and handling of traffic to quad-100.
With this hook wired, magicDNS queries over UDP are now handled within
netstack. The existing logic in wgengine to handle magicDNS remains for now,
but its hook operates after the netstack hook so the netstack implementation
takes precedence. This is done in case we need to support platforms with
netstack longer than expected.

This is in prep for using this package for the web API too (it has the

This starts to refactor tsdial.Dialer's name resolution to have
different stages: in-memory MagicDNS vs system resolution. A future
change will plug in ExitDNS resolution.
This also plumbs a Dialer into netstack and unexports the dnsMap
internals.
And it removes some of the async AddNetworkMapCallback usage and
replaces it with synchronous updates of the Dialer's netmap
from LocalBackend, since the LocalBackend has the Dialer too.

Not done yet, but this move more of the outbound dial special casing
from random packages into tsdial, which aspires to be the one unified
place for all outbound dialing shenanigans.
Then this plumbs it all around, so everybody is ultimately
holding on to the same dialer.
As of this commit, macOS/iOS using an exit node should be able to
reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt
to stay within the Network Extension.
A number of steps remain, including but limited to:
* move a bunch more random dialing stuff
* make netstack-mode tailscaled be able to use exit node's DNS proxy,
teaching tsdial's resolver to use it when an exit node is in use.
