instead, which also gives us a place to add future stuff.

Not for end users (unless directed by support). Mostly for ease of
development for some upcoming webserver work.

The //go:build syntax was introduced in Go 1.17:
https://go.dev/doc/go1.17#build-lines
gofmt has kept the +build and go:build lines in sync since
then, but enough time has passed. Time to remove them.
Done with:
perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build')

It is currently a `ipn.PrefsView` which means when we do a JSON roundtrip,
we go from an invalid Prefs to a valid one.
This makes it a pointer, which fixes the JSON roundtrip.
This was introduced in 0957bc5af2.

This switches from using an atomic.Bool to a mutex for reasons that are
described in the commit, and should address the flakes that we're still
seeing.

* 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.

Poller.C and Poller.c were duplicated for one caller. Add an accessor
returning the receive-only version instead. It'll inline.
Poller.Err was unused. Remove.
Then Poller is opaque.
The channel usage and shutdown was a bit sketchy. Clean it up.
And document some things.

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).

The macOS and iOS apps that used the /localapi/v0/file-targets handler
were getting too many candidate targets. They wouldn't actually accept
the file. This is effectively just a UI glitch in the wrong hosts
being listed as valid targets from the source side.

* 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

This field allows the control server to provide explicit information
about how to connect to it; useful if the client's link status can
change after the initial connection, or if the DNS settings pushed by
the control server break future connections.

The GitHub CodeQL scanner flagged the localapi's cert domain usage as a problem
because user input in the URL made it to disk stat checks.
The domain is validated against the ipnstate.Status later, and only
authenticated root/configured users can hit this, but add some
paranoia anyway.
