DO NOT MERGE. Initial commit for ExploreByTouchHelper class.

This helper class simplifies the implementation of accessibility in
custom views that would otherwise need AccessibilityNodeProvider. It
supports single-depth virtual view hierarchies and enforces guidelines
about what properties must be set on accessibility nodes and events.

Additional supporting code has been added to the ViewCompat and
ViewParentCompat.
