They were entirely redundant and 1:1 with the status field

For now the method has only one interface (the same as the func it's
replacing) but it will grow, eventually with the goal to remove the
controlclient.Status type for most purposes.

just use the zero value.

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.

We would end up with duplicate profiles for the node as the UserID
would have chnaged. In order to correctly deduplicate profiles, we
need to look at both the UserID and the NodeID. A single machine can
only ever have 1 profile per NodeID and 1 profile per UserID.
Note: UserID of a Node can change when the node is tagged/untagged,
and the NodeID of a device can change when the node is deleted so we
need to check for both.

* Plumb disablement values through some of the internals of TKA enablement.
* Transmit the node's TKA hash at the end of sync so the control plane understands each node's head.
* Implement /machine/tka/disable RPC to actuate disablement on the control plane.

When `setWgengineStatus` is invoked concurrently from multiple
goroutines, it is possible that the call invoked with a newer status is
processed before a call with an older status. e.g. a status that has
endpoints might be followed by a status without endpoints. This causes
unnecessary work in the engine and can result in packet loss.
This patch adds an `AsOf time.Time` field to the status to specifiy when the
status was calculated, which later allows `setWgengineStatus` to ignore
any status messages it receives that are older than the one it has
already processed.

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.

LocalBackend.Shutdown's docs say:
> The backend can no longer be used after Shutdown returns.
Nevertheless, TestStateMachine blithely calls Shutdown, talks some smack,
and continues on, expecting things to work. Other uses of Shutdown
in the codebase are as intended.
Things mostly kinda work anyway, except that the wgengine.Engine has been
shut down, so calls to Reconfig fail. Those get logged:
> local.go:603: wgengine status error: engine closing; no status
but otherwise ignored.
However, the Reconfig failure caused one fewer call to pause/unpause
than normal. Now the assertCalls lines match the equivalent ones
earlier in the test.
I don't see an obvious correct replacement for Shutdown in the context
of this test; I'm not sure entirely what it is trying to accomplish.
It is possible that many of the tests remaining after the prior call
to Shutdown are now extraneous. They don't harm anything, though,
so err on the side of safety and leave them for now.

Concurrent calls to LocalBackend.setWgengineStatus
could result in some of the status updates being dropped.
This was exacerbated by 92077ae78c,
which increases the probability of concurrent status updates,
causing test failures (tailscale/corp#2579).
It's going to take a bit of work to fix this test.
The ipnlocal state machine is difficult to reason about,
particularly in the face of concurrency.
We could fix the test trivially by throwing a new mutex around
setWgengineStatus to serialize calls to it,
but I'd like to at least try to do better than cosmetics.
In the meantime, commit the test.
