New orientation handling.  Only impacts SDK (aapt dump badging).

This is a new way of determining whether an application requires
specific orientations, done by looking at any requirements in its
activity tags.  Note that this won't catch all possible issues,
because applications can still force an orientation through Java
APIs, but the vast majority of applications that actually require
a specific orientation should be doing it this way because it the
easiest way and the only way to cleanly launch into the app from
a different orientation without doing some serious activity tricks.
