First pass at reworking screen density/size APIs.

This changes the names of the directories in aapt, to what you see
in the list of DpiTest resources.  Also adds a new "long" configuration
for wide screens, which the platform sets appropriate, and introduces
a new kind of resizeability for not large but significantly larger
than normal screens which may have compatibility issues.
