Settings: SuperSU from Settings

If SuperSU is installed, show an entry in Settings below
"Developer options", which launches SuperSU when tapped.
At boot time SuperSU will detect if com.android.settings
contains the resources from this patch, and if so it
will hide itself from the launcher. This was implemented
in v1.85, so we only show the entry if the installed
SuperSU version is at least that.

Bluetooth:GAP: Handle exception while unregistering the Receiver

Handle the IllegalArgumentException while unregistering the
Receiver.

Usually when user presses both cancel and okay for the disconnect
dialog, OnClickListener will be called twice for both options,
and for the second time it is expected that receiver would have
already unregistered.
