55bb7314f2 control/controlclient: replace a status func with Observer interface
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.

Updates #1909

767e839db5 all: implement lock revoke-keys command
The revoke-keys command allows nodes with tailnet lock keys
to collaborate to erase the use of a compromised key, and remove trust
in it.

golang-ci, fixes the issues reported, and adds a GitHub Action to check

71029cea2d all: update copyright and license headers
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.

Updates #6865

390d1bb871 Revert "ipn,types/persist: store disallowed TKA's in prefs, lock local-disable"
This reverts commit f1130421f0.

It was submitted with failing tests (go generate checks)

Requires a lot of API changes to fix so rolling back instead of
forward.

By always firing off a sync after enablement, the control plane should know the node's TKA head
at all times.

235309adc4 all: store NL keys per profile
This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct.
This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey.

It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional
to be able to delete the "/tka" dir if it exists.

This means that we will have a unique key per profile, and a unique directory per profile.

Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not
delete the ChonkDir.

d98305c537 cmd,ipn/ipnlocal,tailcfg: implement TKA disablement
* 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.

There is a partner PR for the control server I'll send shortly.

a515fc517b ipn/ipnlocal: make tkaSyncIfNeeded exclusive with a mutex
Running corp/ipn#TestNetworkLockE2E has a 1/300 chance of failing, and
deskchecking suggests thats whats happening are two netmaps are racing each
other to be processed through tkaSyncIfNeededLocked. This happens in the
first place because we release b.mu during network RPCs.

To fix this, we make the tka sync logic an exclusive section, so two
netmaps will need to wait for tka sync to complete serially (which is what
we would want anyway, as the second run through probably wont need to
sync).

8602061f32 ipn/ipnlocal,tka: Fix bugs found by integration testing
* tka.State.staticValidateCheckpoint could call methods on a contained key prior to calling StaticValidate on that key
 * Remove broken backoff / RPC retry logic from tka methods in ipn/ipnlocal, to be fixed at a later time
 * Fix NetworkLockModify() which would attempt to take b.mu twice and deadlock, remove now-unused dependence on netmap
 * Add methods on ipnlocal.LocalBackend to be used in integration tests
 * Use TAILSCALE_USE_WIP_CODE as the feature flag so it can be manipulated in tests
