... so callers can provide the AuthKey via mechanisms other than
environment variables which means multiple Servers can't be started
concurrently in the same process without coordination.

Whenever the SSH policy changes we revaluate all open connections to
make sure they still have access. This check was using the wrong
timestamp and would match against expired policies, however this really
isn't a problem today as we don't have policy that would be impacted by
this check. Fixing it for future use.

(breaking up parts of another change)
This adds a PacketFilter hashing benchmark with an input that both
contains every possible field, but also is somewhat representative in
the shape of what real packet filters contain.

When there are group policy entries for the NRPT that do not belong to Tailscale,
we recognize that we need to add ourselves to group policy and use that registry
key instead of the local one. We also refresh the group policy settings as
necessary to ensure that our changes take effect immediately.

Link-local addresses on the Tailscale interface are not routable.
Ideally they would be removed, however, a concern exists that the
operating system will attempt to re-add them which would lead to
thrashing.
Setting SkipAsSource attempts to avoid production of packets using the
address as a source in any default behaviors.
Before, in powershell: `ping (hostname)` would ping the link-local
address of the Tailscale interface, and fail.
After: `ping (hostname)` now pings the link-local address on the next
highest priority metric local interface.

This is for an upcoming blogpost on how to manage Tailscale ACLs using a
GitOps flow. This tool is intended to be used in CI and will allow users
to have a git repository be the ultimate source of truth for their ACL
file. This enables ACL changes to be proposed, approved and discussed
before they are applied.

Client.SetExpirySooner isn't part of the state machine. Remove it from
the Client interface.
And fix a use of LocalBackend.cc without acquiring the lock that
guards that field.

Regression from 09afb8e35b, in which the
same reflect.Value scratch value was being used as the map iterator
copy destination.
Also: make nil and empty maps hash differently, add test.

Use the "tailscaled" prefix instead of "tsnet" for state file names:
1. It is consistent with the pre-existing {{Dir}}/tailscaled.state file.
2. It makes the file layout of `tsnet` and `tailscaled` identical,
so that they are compatible with each other.

It is not idiomatic for Go code to panic for situations that
can be normal. For example, if a server receives PrivateID
from a client, it is normal for the server to call
PrivateID.PublicID to validate that the PublicID matches.
However, doing so would panic prior to this change.
