Restructure the Transition support library
Transition classes no longer delegate to platform Transitions.
Underlying features are separated into their own compatibility layers.
- ViewOverlay and ViewGroupOverlay (platform: 18)
- WindowId (platform: 18)
- ViewGroup.suppressLayout (platform: 19, not backported yet)
This does not change behaviors except for the followings:
- On API level 18, WindowId and ViewOverlay delegate to the platform
- Transition is Cloneable
- Inheriting Visibility now works fine
Test: All existing tests and VisibilityTest pass on 15, 16, 18, 19, and
25
