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.

Forcing the insecure protocol (and perserving the port number) is only
desired for localhost testing, in prod we need to use wss:// to avoid
mixed-content errors.

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.

This commit adds a helper to check if Tailscale SSH is enabled. We're
currently checking the SSH_HostKeys field in a few places, but later
plan to add an explicit bool. This helper makes the check and any future
changes easier.

On DSM7 as a non-root user it'll run into problems.
And we haven't tested on DSM6, even though it might work, but I doubt
it.

Currently we only support "via-<site-id>.<IPv4>", however that does not
work with Google Chrome which parses `http://via-1.10.0.0.1` as a search
string and not as a URL. This commit introduces "<IPv4>.via-<site-id>"
(`http://10.0.0.1.via-1`) which is parsed correctly by Chrome.

This makes it so that the user is notified that the action
they are about to take may result in them getting disconnected from
the machine. It then waits for 5s for the user to maybe Ctrl+C out of
it.
It also introduces a `--accept-risk=lose-ssh` flag for automation, which
allows the caller to pre-acknowledge the risk.
The two actions that cause this are:
- updating `--ssh` from `true` to `false`
- running `tailscale down`

Currently, killing a SCP copy with a Ctrl+C leaves the session hanging
even though the stdout copy goroutine fails with an io.EOF. Taking a
step back, when we are unable to send any more data back to the client
we should just terminate the session as the client will stop getting any
response from the server anyways.
