The derphttp client automatically reconnects upon failure.
RunWatchConnectionLoop called derphttp.Client.WatchConnectionChanges
once, but that wrapper method called the underlying
derp.Client.WatchConnectionChanges exactly once on derphttp.Client's
currently active connection. If there's a failure, we need to re-subscribe
upon all reconnections.
This removes the derphttp.Client.WatchConnectionChanges method, which
was basically impossible to use correctly, and changes it to be a
boolean field on derphttp.Client alongside MeshKey and IsProber. Then
it moves the call to the underlying derp.Client.WatchConnectionChanges
to derphttp's client connection code, so it's resubscribed on any
reconnect.
Some paranoia is then added to make sure people hold the API right,
not calling derphttp.Client.RunWatchConnectionLoop on an
already-started Client without having set the bool to true. (But still
auto-setting it to true if that's the first method that's been called
on that derphttp.Client, as is commonly the case, and prevents
existing code from breaking)

This is not currently exposed as a user-settable preference through
`tailscale up` or `tailscale set`. Instead, the preference is set when
turning the web client on and off via localapi. In a subsequent commit,
the pref will be used to automatically start the web client on startup
when appropriate.

Allows for serving the web interface from tailscaled, with the
ability to start and stop the server via localapi endpoints
(/web/start and /web/stop).
This will be used to run the new full management web client,
which will only be accessible over Tailscale (with an extra auth
check step over noise) from the daemon. This switch also allows
us to run the web interface as a long-lived service in environments
where the CLI version is restricted to CGI, allowing us to manage
certain auth state in memory.
ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for
ios builds to satisfy ios restriction from adding "text/template"
and "html/template" dependencies.

We were inconsistent whether we checked if the feature was already
enabled which we could do cheaply using the locally available status.
We would do the checks fine if we were turning on funnel, but not serve.
This moves the cap checks down into enableFeatureInteractive so that
are always run.

On Windows, the idiomatic way to check access on a named pipe is for
the server to impersonate the client on its current OS thread, perform
access checks using the client's access token, and then revert the OS
thread's access token back to its true self.
The access token is a better representation of the client's rights than just
a username/userid check, as it represents the client's effective rights
at connection time, which might differ from their normal rights.
This patch updates safesocket to do the aforementioned impersonation,
extract the token handle, and then revert the impersonation. We retain
the token handle for the remaining duration of the connection (the token
continues to be valid even after we have reverted back to self).
Since the token is a property of the connection, I changed ipnauth to wrap
the concrete net.Conn to include the token. I then plumbed that change
through ipnlocal, ipnserver, and localapi as necessary.
I also added a PermitLocalAdmin flag to the localapi Handler which I intend
to use for controlling access to a few new localapi endpoints intended
for configuring auto-update.

The progress printer was buggy where it would not print correctly
and some of the truncation logic was faulty.
The progress printer now prints something like:
go1.21.3.linux-amd64.tar.gz 21.53MiB 13.83MiB/s 33.88% ETA 00:00:03
where it shows
* the number of bytes transferred so far
* the rate of bytes transferred
(using a 1-second half-life for an exponentially weighted average)
* the progress made as a percentage
* the estimated time
(as calculated from the rate of bytes transferred)
Other changes:
* It now correctly prints the progress for very small files
* It prints at a faster rate (4Hz instead of 1Hz)
* It uses IEC units for byte quantities
(to avoid ambiguities of "kb" being kilobits or kilobytes)

Previously we were just smushing together args and not trying
to parse the values at all. This resulted in the args to testwrapper
being limited and confusing.
This makes it so that testwrapper parses flags in the exact format as `go test`
command and passes them down in the provided order. It uses tesing.Init to
register flags that `go test` understands, however those are not the only
flags understood by `go test` (such as `-exec`) so we register these separately.

This partially reverts commits a61a9ab087

4823a7e591.
The goal of that commit was to reapply known config whenever the
container restarts. However, that already happens when TS_AUTH_ONCE was
false (the default back then). So we only had to selectively reapply the
config if TS_AUTH_ONCE is true, this does exactly that.
This is a little sad that we have to revert to `tailscale up`, but it
fixes the backwards incompatibility problem.
