Doing so causes the process to restart when the activity is cleared,
even when no tunnel is running. I fear this might also lead to the
current flurry of DeadSystemExceptions.

Nathan Chance dropped the ball repeatedly and never maintained this in a
consistent way that anybody could use. With Android 12 out now, just
drop it all together. A bummer, but I don't see much of a choice.

wg-quick has supported this for a while, but not the config layer, and
not the Go backend, so wire this all up.

This has several problems: 1) it blocks the main thread; 2) it doesn't
distinguish between a permanent error and a transient one; 3) the 10
seconds is hard coded; 4) there's no way for the user to cancel it.
We'll have to improve this.

wgTurnOff can block for a while, in which case, calling getStatistics
will use a stale handle and stale tunnel. Not only that, but wgGetConfig
might return null, in which case string.split throws.

Modern Android likes to kill processes to free ram and resources. When
kernel-mode WireGuard is in use, this is quite alright with us, since
the app doesn't actually need to consume any resources at all in order
for the tunnel to run. So, we want to allow and encourage this resource
frugality. However, when the quick settings tile is being used or when
the app is referenced otherwise, the app will occasionally be restarted,
to, for example, repaint the quick settings tile. This is also fine, as
the process winds up being short-lived again. But, since process
initialization means asking for a new root shell in order to check on
kernel-mode WireGuard, this means that Magisk raises a systemwide toast.
On some phones, this happens each and every time that the notification
shade is pulled down. It's not only annoying but it sometimes obscures
other notifications that users want to see, prompting their pulling down
of the notification shade in the first place. In order to get rid of
this nuisance, just disable these notifications and extraneous logs, so
that we don't clutter the system every time that the process is
opportunistically killed and restarted.

/data/adb/modules has been the location for modules since v18.0 and nobody
should reasonably be on any older version anymore. This has continued to
work for this long because Magisk created symlinks for backwards compat. However,
these symlinks are not created anymore on Android 11, which is where this
problem first surfaced.

This is covered under SYNTAX_ERROR which feels like a reasonable choice,
so get rid of this unused field and associated resource string.

It's not right to blindly follow all of AndroidStudio's suggestions,
especially for things in tunnel/ which comprise useful API.

Hacking things up via gradle is not right, and package-info.java poses
problems with two modules, so instead we just apply it manually to every
class.
Remember to add this to new classes!

Note that this currently doesn't play well with people activating
wg-quick tunnels from outside the app. Those tunnels won't be
deactivated. But presumably that's desired behavior anyway, considering
people are mucking around at the command line.
