keyguard: fix layout for hdpi & mdpi devices

800x480px dpi devices have less screen space than the xhdpi devices
Google designed the layout for and the layout needs adjustment.

- Reduce the lockscreen security container size such that the clock
  widget has enough space to display its content.
- In the SIM PIN/PUK view, Google put an empty widget on top, but
  we don't have space for that, increase its size such that the
  widget practically disappears.

This should not have any effect on devices with larger screens.

Ported from cm-10.2.
* Removed invalid mdpi layout leftover from framework-res
* Fix keyguard for mdpi devices too

Keyguard: fix statusbar lags when default widget shown.

When statusbar became expanded KeyguardStatusView receives
onKeyguardVisibilityChanged callback and refreshes ClockView.
Because it receives more than one call and every time it reads
new values from resources it cause lags in opening statusbar panel.

Replace this code with BroadcastReceiver and ContentObserver to
refresh it only in case something was changed.
