This PR corrects a small mistake in the minimal example in the Documentatioin of the FlatList component.
1. Create a vanilla React Native project.
2. Create the components involved in the minimal example of FlatList.
3. Run to see if the `selected` property of the `MyListItem` changes as intended.
Currently the example has this mistake so an error will show up when running:

Hey there :)

In a FlatList, I wanted to show some placeholder when my data is empty (while keeping eventual Header/Footer/RefreshControl).
A way around this issue would be to do something like adding a `ListHeaderComponent` that checks if the list is empty, like so:
```js
ListHeaderComponent={() => (!data.length ? <Text style={styles.noDataText}>No data found</Text> : null)}
```
But I felt it was not easily readable as soon as you have an actual header.
This PR adds a `ListEmptyComponent` that is rendered when the list is empty.
I added tests for VirtualizedList, FlatList and SectionList and ran `yarn test -- -u`. I then checked that the snapshots changed like I wanted.
I also tested this against one of my project, though I had to manually add my changes because the project is on RN 0.43.
Here are the docs screenshots:

Summary:
The main reason to use **VirtualizedList** is to set the `getItem` and `getItemCount` props, so having default values for these props makes things error prone.
* In **VirtualizedList**, changed the `getItem` and `getItemCount` props from optional to required, and removed default values.
* Ensured that implementing classes **FlatList** and **SectionVirtualizedList** are always passing these props.
* Updated VirtualizedList-test.js accordingly.

Summary:
- If the initial render doesn't extend past `onEndReachedThreshold` it is likely that onEndReached won't get called until scroll, which can be a bad experience if the `initialNumToRender` is very close to the viewport height. This happens because when `onContentSizeChange`, `onLayout` may not have fired yet so we don't know what the `visibleLength` is. Fix is to also call `maybeCallOnEndReached` in `_onLayout` as well.
- We have an optimization that does hi-pri render window updates when scrolling quickly and the content reaches the edge of the viewport, but there is also an important case where the user has scrolled to the end of the content and is waiting for a network response. Once the new data comes in, we want to render it ASAP because the user is waiting for it. To solve this we refactor our scheduling code into a shared function that always checks if it should be a hi-pri update instead of just in `_onScroll`.

Summary:
`contentSize` was removed from both iOS and Android, tests was updated.
USE `onContentSizeChange` INSTEAD.
Why?
* It always was a hack;
* We already have dedicated event for it: `onContentSizeChange`;
* `onChange` has nothing to do with layout actually;
* We have to maintain `onChange` handler as fast and simple as possible, this feature complicates it a lot;
* It was undocumented feature;
* We already have native auto-expandable <TextInput>, so it illuminates 99% current use cases of this feature.

Summary:
Looking to address a few new `FlowFixMe`s I had to do some minor refactoring of `MessageQueue`. Has the advantage of (IMO) making things clearer by removing a redundant counter and some gratuitous bitwise operations.
Previously `_callbacks` was an array of `?Function`s where even elements were failure callbacks and odd elements were successes. Each new call incremented `_callID` by one and `_callbackID` by two. I've changed this to use two arrays `_successCallbacks` and `_failureCallbacks` indexed by `callID`. That made the `_callbackID` counter unnecessary and reduced the need for computed indices.
Tested with flow and a quick play with UIExplorer.

Summary:
These got smashed together with some weird rebase snafu. They are pretty intertwined anyway so the value of
separate commits is minimal (e.g. separate commits would not revert cleanly anyway).
== [lists] better fill rate logging (previously D4907958)
After looking through some production data, I think this will address all the issues we're seeing. Now:
- Header/Footer getting no longer counted as blank.
- Avoid floating point for Scuba.
- Compare actual time of blankness, not just samples.
- Include both "any" vs. "mostly" blank (similar to 1 and 4 frame drops).
- Include events where there is no blankness so we have a baseline.
- Remove events with too few samples
**Test Plan: **
A bunch of scrolling in FlatListExample
T17384966
== [Lists] Update SectionSeparatorItem docs (previously D4909526)
Forgot to update the language here when we modified the behavior with the introduction of separator
highlighting support.
** Test Plan: **
nope.
== [Lists] Add renderSectionFooter prop to SectionList (previously D4923353)
Handy for things like "see more" links and such.
The logic here is to render the footer last, *after* the bottom section separator. This is to preserve
the highlighting behavior of the section separator by keeping it adjacent to the items.
**Test Plan: **
Added to snapshot test and example:
{F66635525}
{F66635526}
== [SectionList] Add a bunch more info for rendering items and separators (previously D4923663)
This extra info can be helpful for rending more complex patterns.
**Test Plan: **
Made snapshot test more comprehensive and inspected the output.
== [Lists] reduce render churn (previously D4924639)
I don't think the velocity based leadFactor is helping and might actually be hurting because
it causes a lot of churn in the items we render.
Instead, this diff introduces fillPreference which biases the window expansion in the direction of scroll,
but doesn't actually affect the final bounds of the window at all, so items that are already rendered are
more likely to stay rendered.
**Test Plan: **
Played around in debug mode and watched the overlay - seems better. Also tests all pass.
T16621861
== [Lists] Add initialScrollIndex prop
Makes it easy to load a VirtualizedList at a location in the middle of the content without
wasting time rendering initial rows that aren't relevant, for example when opening an infinite calendar
view to "today".
**Test Plan: **
With debug overlay, set `initialScrollIndex={52}` prop in `FlatListExample` and
and see it immediately render a full screen of items with item 52 aligned at the top of the screen. Note
no initial items are mounted per debug overlay. Scroll around a bunch and everything else seems to work
as normal.
No SectionList impl since `getItemLayout` isn't easy to use there.
