Summary:
What existing problem does the pull request solve?
My motivation was to improve the documentation for ListView and ListViewDataSource because I always have trouble remembering how they work and the documentation was lacking an example for `cloneWithRowsAndSections`
My PR does the following:
* add a note about how headers and footers are rendered on a horizontal ListView
* fix a typo in an example
* clarify that the sectionIdentities should match the keys or array indexes of the data source
* add an example of cloneWithRowsAndSections
* add notes on the return values of `getRowCount` and `getRowAndSectionCount`
n/a; documentation only

Summary: Optimize ScrollView by adding flag "DEPRECATED_sendUpdatedChildFrames" to gate whether updatedChildFrames data is computed and propagated on scroll events. The frame data is used in ListView by the onChangeVisibleRows prop. When this prop is not defined, unnecessary computation in ScrollView should not be performed.

Summary:
Flashing scroll indicators is a standard behavior on iOS to show the user there's more content.
Launch RNTester on iOS, go to the ScrollView section, tap the "Flash scroll indicators" button.
You'll see this:
I've exposed the method `flashScrollIndicators` on all scrolling components that were already exposing a `scrollToXXX` method so it's usable from those components using a ref.
Let me know what you think.

Summary:
When ListViews has multiple sections, then rowIDs are required to be unique per section.
However the ListViewMock required rowIDs to be unique per whole list.
This change fixes the limitation of ListViewMock.
