    keyguard: fix layout for sw320dp 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-fix layout for sw320dp devices

    Default values need to be defined in sw360dp or larger devices will
    pick up sw320dp values automatically.

    On the maguro device the keyguard isn't properly centered.

keyboard: re-add code to detect lid state

This was lost in the cm-11 merge. Without this, a change in lid state
isn't generated to light up the keyboard backlight

Framework: Fix GSM signal strength

Certain OEM gsm ril libs send back a bogus value for LTE signal
that causes SignalStrength.java to default to LTE and report
incorrect signal values.
Use prop value ro.telephony.ril.v3=signalstrength to get proper
GSM signal reading on certain devices.
