This is part 3 of the fix for bug 2364220 "Accessibility improvements for
ending calls".
This change adds a checkbox under "Accessibility settings" to control the
new Settings.Secure.INCALL_POWER_BUTTON_BEHAVIOR value, which allows the
user to specify that the Power button should hang up while in-call
(instead of just turning off the screen.) The checkbox is only shown on
devices that actually have a POWER button.
Yeah, it's a little strange having this under Accessibility (since it's not
that obvious *why* this feature is accessibility-related), but there's no
obvious better place. See discussion in the bug for more info.

(Google's open source screen reader) if they go
to the Accessibility settings screen and do not
have any accessibility tools installed.
This is a fix for bug #2250279
