    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.

Framework: disable keyguard widget frame (1/2)

And another user request.  But...I can understand
	it now that I see it without.  They actually
	look quite nice this way.

Fix visibility of camera widget on insecure lock screens with DPM

The camera widget should be visible on an insecure lockscreen even
with the KEYGUARD_DISABLE_SECURE_CAMERA policy flag set.

Prevent Lockscreen album art from activating FLAG_KEEP_SCREEN_ON

This is a small fix to the showWallpaper method, in which a power
consumption problem has been introduced. This showWallpaper method
toggles the window flag FLAG_SHOW_WALLPAPER, when album art is being
shown in Lockscreen. It is important to set pixel format to
PixelFormat.OPAQUE if flag FLAG_SHOW_WALLPAPER is not being set.

If not, an application that uses window flag FLAG_KEEP_SCREEN_ON
will prevent the keyguard from going to sleep and drain battery.

Fix problem where PhoneWindowManager waits for keyguard to draw

This fixes a problem where PhoneWindowManager times out waiting
for keyguard to draw when it's disabled.  Instead, we pass a null
token back which allows PhoneWindowManager to continue.

Fixes bug 11190932

Don't let apps disable the SIM PIN entry screen.

As the user (who controls the app behaviour after all) likely doesn't
see the PIN screen as a lock screen (he likely wants telephony) and the
PIN screen is not shown on a timer-driven basis, it should be treated
specially.

Send out USER_PRESENT broadcast on screen on if lockscreen is disabled.

This makes sure to turn off the notification LED on screen on when the
lockscreen is disabled by lockscreen toggle tile.
