When sending a CLI ping with a specific size, continue to probe all possible UDP
paths to the peer until we find one with a large enough MTU to accommodate the
ping. Record any peer path MTU information we discover (but don't use it for
anything other than CLI pings).

Then use it in tailcfg which had it duplicated a couple times.
I think we have it a few other places too.
And use slices.Equal in wgengine/router too. (found while looking for callers)

We had a misstep with the semantics when applying an optimization that
showed up in the roll into corp. This test ensures that case and related
cases must be retained.

We should be able to freely run `./tool/go generate ./...`, but we're
continually dodging this particular generator. Instead of constantly
dodging it, let's just remove it.

Prevent future problems like we earlier with go.mod replace directives
(e.g. removing our certstore replace in 6d6cf88d82 or wireguard-go
in ea5ee6f87c, both of which were reactions to problems caused by
go.mod replace in non-root modules, often because people are using tsnet
as a library from another module)

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

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.

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.
