We do not need to wait for it to complete. And we might have to
call Shutdown from callback from the controlclient which might
already be holding a lock that Shutdown requires.

QNAP 5.x works much better if we let Apache proxy
tailscale web, which means the URLs can no longer
be relative since apache sends us an internal
URL. Access QNAP authentication via
http://localhost:8080/ as documented in
https://download.qnap.com/dev/API_QNAP_QTS_Authentication.pdf

Maisem spotted the bug. The initial getList call in NewPoller wasn't
making a clone (only the Run loop's getList calls).

Found by tests in another repo. TKA code wasn't always checking enough to be sure a node-key was set for the current state.

There was a mechanism in tshttpproxy to note that a Windows proxy
lookup failed and to stop hitting it so often. But that turns out to
fire a lot (no PAC file configured at all results in a proxy lookup),
so after the first proxy lookup, we were enabling the "omg something's
wrong, stop looking up proxies" bit for awhile, which was then also
preventing the normal Go environment-based proxy lookups from working.
This at least fixes environment-based proxies.
Plenty of other Windows-specific proxy work remains (using
WinHttpGetIEProxyConfigForCurrentUser instead of just PAC files,
ignoring certain types of errors, etc), but this should fix
the regression reported in #4811.

The key changed, but also we have a localapi method to set it anyway, so
use that.

The health package was turning into a rando dumping ground. Make a new
Warnable type instead that callers can request an instance of, and
then Set it locally in their code without the health package being
aware of all the things that are warnable. (For plenty of things the
health package will want to know details of how Tailscale works so it
can better prioritize/suppress errors, but lots of the warnings are
pretty leaf-y and unrelated)
This just moves two of the health warnings. Can probably move more
later.

Run an inotify goroutine and watch if another program takes over
/etc/inotify.conf. Log if so.
For now this only logs. In the future I want to wire it up into the
health system to warn (visible in "tailscale status", etc) about the
situation, with a short URL to more info about how you should really
be using systemd-resolved if you want programs to not fight over your
DNS files on Linux.

This makes it so that the backend also restarts when users change,
otherwise an extra call to Start was required.

Noticed this while debugging something else, we would reset all routes if
either `--advertise-exit-node` or `--advertise-routes` were set. This handles
correctly updating them.
Also added tests.

in the package had different behavior than running just any one test.

Also, move "tailscale status" health checks to the bottom, where they

If the --key-file output filename ends in ".pfx" or ".p12", use pkcs12
format.
This might not be working entirely correctly yet but might be enough for
others to help out or experiment.

Noticed when testing FUS on tailscale-on-macOS, that routing would break
completely when switching between profiles. However, it would start working
again when going back to the original profile tailscaled started with.
Turns out that if we change the addrs on the interface we need to remove and readd
all the routes.

Map is a concurrent safe map that is a trivial wrapper
over a Go map and a sync.RWMutex.
It is optimized for use-cases where the entries change often,
which is the opposite use-case of what sync.Map is optimized for.
The API is patterned off of sync.Map, but made generic.
