Fix 5323545 - FaceLock no longer appears when taking a call

Prior to this fix if the screen was off and a call was received, the
onScreenTurnedOn() callback would bring up the FaceLock service,
which would cover the phone interface.  It now requires the call state
to be CALL_STATE_IDLE to start FaceLock.  When the phone interface
closes, the user is left at the backup lock screen.  Bringing FaceLock
up after a call ends does not seem like the correct thing to do.

While working near the FaceLock callback code, the sleepDevice()
callback was removed because it is no longer used (Fix 5327896).

Some cleanup was also done with regards to KeyguardViewManager.
FaceLock calls were being made from the KeyguardViewManager in
onScreenTurnedOn() and onScreenTurnedOff() via an interface to
LockPatternKeyguardView.  This level of indirection was removed
because it can just be handled inside of the corresponding calls
in LockPatternKeyguardView.  Likewise the FaceLock functionality
inside of hide() in KeyguardViewManager is now in
onDetachedFromWindow() in LockPatternKeyguardView.  Overall this
is much cleaner, especially considering interfacing through
KeyguardViewBase was a bit of a hack.

Patch Set 2:

- Now using KeyguardUpdateMonitor to get phone state

- Removed unnecessary wrapper functions for hiding / viewing
  FaceLock area
  - These were really only there because at one point I was calling
    them from KeyguardViewManager and the naming was confusing

- Removed if(DEBUG) from a couple of log messages that are actually
  warnings that shouldn't show up and I want to know if they happen
  even if I don't have DEBUG set to true
