[1/2] SystemUI: Add time-context headers to the notification header

This commit adds image headers to the notification panel header,
based on the date/time. There are pictures for morning, afternoon
and night, as well as special events like Christmas and new
year's eve.
More will be coming, with eventually a way to use an external
(as in, Internet) provider for those pictures.

SystemUI: fix RecentPanel position in landscape mode.

In landscape mdoe we forcing ltr layout direction. This cause
call to resolvePadding too late and discards paddings
computed by fitSystemWindows. To workaround this we can catch
onRtlPropertiesChanged and force executuin of fitSystemWindows
one more time. To fix scroll issue after padding will be setted
we calling scrollTo with correct position.

pm: Prevent a system_server crash is package name is null

 * If an app is placed on the system partition and it doesn't specify a
   valid package name, system_server will crash forever. Just skip it.
