This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.
Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.
Test: make relevant packages

Bitmap.getGenerationId() can be used by caches to find out if a Bitmap has been
modified. This simply exposes an existing Skia API.
This change also adds a small test app for Canvas hardware acceleration. The new
Bitmap API is required to implement a texture cache.
