Brad Fitzpatrick 5676d201d6 ipn: add a WatchIPNBus option bit to subscribe to EngineStatus changes
So GUI clients don't need to poll for it.

We still poll internally (for now!) but that's still cheaper. And will
get much cheaper later, without having to modify clients once they
start sending this bit.

Brad Fitzpatrick 0a842f353c ipn/ipnserver: move more connection acceptance logic to LocalBackend
Follow-up to #6467 and #6506.

LocalBackend knows the server-mode state, so move more auth checking
there, removing some bookkeeping from ipnserver.Server.

Updates #6417
Updates tailscale/corp#8051

Brad Fitzpatrick b68d008fee envknob: add CanTaildrop (TS_DISABLE_TAILDROP) to disable taildrop on device
This matches CanSSHD (TS_DISABLE_SSH_SERVER) for administratively
disabling the code on a node, regardless of local or server configs.

This can be configured in /etc/default/tailscaled on Linux,
%ProgramData%\Tailscale\tailscaled-env.txt on Windows,
or /etc/tailscale/tailscaled-env.txt on Synology. (see getPlatformEnvFile)

Also delete some dead code and tidy up some docs.

Maisem Ali dd50dcd067 ipn/ipnlocal: handle untagging nodes better
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.

Maisem Ali 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.

Brad Fitzpatrick 3f8e185003 health: add Warnable, move ownership of warnable items to callers
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.
