Fix sdk layout rendering in JB. 

Since JB, com.android.internal.R does not contain all the resources,
instead only the ones that are accessed through Java.
This means we need to dynamically generate IDs for resources that are
private and only accessed from other XML resources. This is done
through the DynamicIdMap class.

Also add a PolicyManager and a PowerManager since those are now
needed by ViewRootImpl?!?
