1.50.0 switched containerboot from using `tailscale up`
to `tailscale login`. A side-effect is that a re-usable
authkey is now re-applied on every boot by `tailscale login`,
where `tailscale up` would ignore an authkey if already
authenticated.
Though this looks like it is changing the default, in reality
it is setting the default to match what 1.48 and all
prior releases actually implemented.

Adds new LoginOnly server option and swaps out API handler depending
on whether running in login mode or full web client mode.
Also includes some minor refactoring to the synology/qnap authorization
logic to allow for easier sharing between serveLoginAPI and serveAPI.

Control sends ExitNodeDNSResolvers when configured for IsWireGuardOnly
nodes that are to be used as the default resolver with a lower
precedence than split DNS, and a lower precedence than "Override local
DNS", but otherwise before local DNS is used when the exit node is in
use.
Neither of the below changes were problematic, but appeared so alongside
a number of other client and external changes. See tailscale/corp#14809.

Appears to be a missing nil handling case. I looked back over other
usage of findRule and the others all have nil guards. findRule returns
nil when no rules are found matching the arguments.

Remove the "JSON" ending, we no longer have a non-JSON version,
it was removed in d74c771 when we switched from the legacy web
client to React.
Also combine getNodeData into serveGetNodeData now that serveGetNodeData
is the single caller of getNodeData.

Prepare for path MTU discovery by splitting up the concept of
DefaultMTU() into the concepts of the Tailscale TUN MTU, MTUs of
underlying network interfaces, minimum "safe" TUN MTU, user configured
TUN MTU, probed path MTU to a peer, and maximum probed MTU. Add a set
of likely MTUs to probe.

We weren't correctly retrying truncated requests to an upstream DNS
server with TCP. Instead, we'd return a truncated request to the user,
even if the user was querying us over TCP and thus able to handle a
large response.
Also, add an envknob and controlknob to allow users/us to disable this
behaviour if it turns out to be buggy (✨ DNS ✨).

The test was sending SIGKILL to containerboot, which results in no
signal propagation down to the bash script that is running as a child
process, thus it leaks.
Minor changes to the test daemon script, so that it cleans up the socket
that it creates on exit, and spawns fewer processes.
