Blank the screen while playing voicemail using proximity sensor.
This commit blanks the screen when the proximity sensor tells us that
there is an object close to the screen.
This is to avoid accidental touching of UI element with your face while
listening to voicemail.
As a consequence, do not enable this if listening to voicemail using the
speaker phone, because in that case we do not need to blank the screen
at all as the user is unlikely to have the phone near their ear.
This is done using a blank view that is placed on top of all other views
and by hiding the action bar. This leave the notification area available
to be accidentally touched, but we cannot hide the notification area
without starting a new activity.
Moreover, we do not want to start a new activity as that would cause our
activity to be stopped, which we do not want to do while the user is
listening to voicemail, as we plan to stop playback when the activity is
paused.
