The tor daemon supports both "SIGNAL HUP" via its control port or the UNIX
signal `kill -HUP` via the terminal as a way to trigger the tor daemon to
reload its config. This is needed for new bridges and hidden services. It
is not necessary to restart everything to add those.

Since running stopService() automatically triggers Service.onDestroy(),
there is a nice way to hook in and run the shutdown procedure. This
provides an obvious point of entry as well as simplifying the shutdown
procedure.
In order for apps to follow the current state of Tor, this broadcasts the
state both locally, since global broadcasts are insecure, and globally, for
any app to receive. The internal workings of Orbot need to use a local
broadcast, otherwise any app could trigger stop, start, etc or DoS in other
ways.
In order to send reliable information to any app using Tor, Orbot itself
needs reliable state broadcasts. Before, there the ON/OFF/STARTING state
were being set multiple times during the process, and sometimes not even in
a useful order (i.e. STARTING ON STARTING ON ON).
This reworks the start/stop procedure into startTor() and stopTor().
As of android-9, java.io.File has native methods for setting permissions,
inherited from Java 1.6. Using these will help deal with compatibility
across devices, since some devices might not have chmod installed.
The code was using global variables that were refreshed from the prefs on
certain occasions. That means that the global vars could easily get out of
sync with the actual values. Instead, just read the prefs directly when
the values are needed, and they will always be up-to-date.
Following the Android system naming convention, this uses constants for
the action and extra names for Intents. This makes it much easier to track
which "log" is which, since there are "log" actions, extras, and messages.
When clicking on "Wizard" from the menu, then clicking back, it gets stuck
in a strange back stack purgatory, and then randomly changes the language.
So purge the wizard stuff for now, and add back the parts that are still
needed once that is all figured out.
This also simplifies the refactoring of the Intent handling.

Note that Java uses several deprecated two-letter codes. The Hebrew ("he")
language code is rewritten as "iw", Indonesian ("id") as "in", and Yiddish
("yi") as "ji". This rewriting happens even if you construct your own
Locale object, not just for instances returned by the various lookup
methods.
This leaves the default Locale unchanged, i.e. Locale.setDefault(). This
also will immediately change the language after the user selects it in the
pref.
The recommended way to send a START_TOR Intent is using
startActivityWithResult() so that the sender knows when Tor is actually
started. The return includes an Intent that can also include the config
info for the proxies that Orbot runs. Right now, this is based on the
app defaults, but ultimately, it should dynamically get the port numbers
for cases like Samsung devices where there is a port conflict.
The Languages utility class merges the techniques from ChatSecure and
Courier. It fetches the supported locales from the APK itself, and fetches
the native names of the languages from the system.
There are a couple of different times when Orbot will be unable to kill the
running processes. One example is when Orbot is running, then uninstalled,
then installed again.

Since most people using devices without Google Play will be in China, where
Google is generally blocked, instead direct people to f-droid.org unless
they have Google Play installed.
This automatically detects whether Google Play or FDroid is installed, if
so, clicking the promo app button will take the user straight to the
install page. If neither is installed, then the user is taken to the page
for that app on https://f-droid.org
