SystemUI: Set Status bar opaque during drawer pulldown on tablets only

The status bar only needs to be set as opaque when the notification
drawer is pulled down on 600dp and 720dp devices. On phones, this
is unnecessary as the top header of the drawer covers the status
bar on the phone UI. This change makes a huge difference in
reponsiveness on devices that run the phone UI as there is no
longer a delay before the drawer appears when interacting with it
on an activity with transclucent window decor.

Patch Set 3: Fix formatting, adjust comment
Patch Set 5: Delete file derp

frameworks/base: Fix the random UI corruption

On low memory device, when a view goes to background. Its HW layer cache
will be destroyed to release memory. There is a very rare case that the
hardware render is not valid when destroy the layer, so the layer is not
destroyed and reused when the view comes to foreground. But the GL
context has changed, so the view is not rendered correctly due to its
HW layer cache. To fix this issue, destroy the layer in a safelyRun. Make
sure the layer is destroyed correctly.
