Postpone accessibility events to post layout
During a layout calculation, some accessibility events
might be triggered by the view system synchronously.
These events are very hard to handle for a LayoutManager
since it is in the middle of calculating a layout but
received an accessibility request while trying to
obtain / add or remove a View.
Instead, RecyclerView will silently block these calls
until the end of the layout or scroll calculation and
then dispatch content change to avoid these race
conditions.
This CL also backports more Accessibility code to support
library.

Nested scrolling: android-support-v4 edition
Implement the nested scrolling patterns from Android 5.0 Lollipop for
use on older platform versions.
Custom nested scrolling child views should implement the new interface
NestedScrollingChild. These views can instantiate a
NestedScrollingChildHelper and delegate overridden interface and
View/ViewGroup methods to the helper methods of the same name. The
helper will manage associated state and behavior.
Similarly, custom nested scrolling ViewGroups should implement
NestedScrollingParent and create a NestedScrollingParentHelper,
delegating methods of the same name to the helper.
Nested scrolling methods should be invoked via the
ViewCompat/ViewParentCompat shims. These shims will delegate to the
proper implementation for both framework and support views that allow
nested scrolling.
Now with bonus NestedScrollView!

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.
