fixup! Bug 40597: Implement TorSettings module
Implement an Android-specific transport, that relies on the Java side
to start the domain fronting proxy.

Bug 42247: Android helpers for the TorProvider
GeckoView is missing some API we use on desktop for the integration
with the tor daemon, such as subprocess.
Therefore, we need to implement them in Java and plumb the data
back and forth between JS and Java.

fixup! Bug 40933: Add tor-launcher functionality
Use a custom TorProcessAndroid in the TorProvider on Android.

fixup! Bug 42247: Android helpers for the TorProvider
Test to plumb down the circuit display data

fixup! Bug 42247: Android helpers for the TorProvider
Switch from a gate based on the update channel to a gate based on a
pref.
Also, draft the JS part for TorSettings events.

fixup! Bug 42247: Android helpers for the TorProvider
Keep only a TorProcess in memory at a time.
When we forget a process from JS, we also delete the Java instance.
When we start a new process, we delete the old one if any (but emit a
warning in logs, in case).

fixup! Bug 40933: Add tor-launcher functionality
Make TorProcessAndroid.forget signal to Java the forget request.
