Summary:
We are working on making the empty object literal `{}` have the type `{}` - i.e. exact empty object - rather than being unsealed.
Making this change exposes a variety of errors. We can prevent these errors by annotating what we want the type of the empty object to be.

[General][Fixed] - Remove illegal private property access in VirtualizedSectionList.scrollToLocation
`VirtualizedSectionList.scrollToLocation` internally uses `VirtualizedList`'s `_getFrameMetricsApprox` method. This method is private by convention (since it's `_`-prefixed), but under certain build setups this is also enforced at runtime, so using `scrollToLocation` can throw an error.
Here, we rename this internal method to `__getFrameMetricsApprox` (adding another leading underscore) which opts it out of being treated as private, while still communicating that it's not part of the public API. We also delete the Flow error suppression that masked this issue.
For reference: This convention for private methods (including the double-underscore opt out) has its roots in Facebook's pre-Babel [JSTransform](https://github.com/facebookarchive/jstransform/blob/master/visitors/es6-class-visitors.js) compiler and is implemented in Flow as [`munge_underscores=true`](https://flow.org/en/docs/config/options/#toc-munge-underscores-boolean).

Summary:
These components had props that were poorly typed and let many things through. This diff tightens that all up.
The main difference in this diff is using `{...BaseProps, ...LocalProps }` instead of `BaseProps & LocalProps`.
The majority of the changes in this diff is reducing duplicated prop definitions. For example, FlatList defines a bunch of props that VirtualizedList also defines. Since FlatList extends those props, using spread now means that FlatList can't duplicate those props. So I've moved the definitions to the correct base file and deleted the duplicates.

Summary:
first, I edited this post so that the comment below are NOT relevant any more
problem: `scrollToLocation` behavior in SectionList on master is inconsistent between platforms.
Recently, there have been two PRs changing this function: https://github.com/facebook/react-native/pull/21577 and https://github.com/facebook/react-native/pull/24034
let me just quote the [docs](https://facebook.github.io/react-native/docs/sectionlist#scrolltolocation) here
> Scrolls to the item at the specified sectionIndex and itemIndex (within the section)
originally, the code was `let index = params.itemIndex + 1;`
so if we call
```js
node.scrollToLocation({
animated: false,
itemIndex: 0,
sectionIndex: 0,
viewPosition: 0,
viewOffset: 0,
});
```
inside scrollToLocation, index is incremented and that results into the list scrolling to the first item (the first section heading is not visible - see the gif). If I specify `itemIndex = -1`, it will scroll all the way up. I was expecting `itemIndex = 0` to bring me all the way up, so that the first section heading is visible. Not sure which way this should work but at least this behavior is in line with the docs.
next, there was https://github.com/facebook/react-native/pull/21577 that changed it to
`let index = Platform.OS === 'ios' ? params.itemIndex: params.itemIndex - 1;`
so that https://github.com/facebook/react-native/issues/18098 is fixed. The PR had a bug and so next, there was https://github.com/facebook/react-native/pull/24034 that changed it to
`let index = Platform.OS === 'ios' ? params.itemIndex : params.itemIndex + 1;`
the reasoning was
> Note however, how the sign for non iOS changed from + to - causing a crash on Android when trying to scroll to index 0 as that will be evaluated to -1 instead of 1 and thus be out of bounds.
with this change, the list does not crash. However, the behavior is not consistent between platforms (see gifs):
So, this PR works under the assumption that
```js
node.scrollToLocation({
animated: false,
itemIndex: 0,
sectionIndex: 0,
viewPosition: 0,
viewOffset: 0,
});
```
should scroll all the way up, so that even the first section heading is visible. This should keep this bug https://github.com/facebook/react-native/issues/18098 fixed. However, this change means different behavior from how it used to be and from how it is documented, which should be pointed out in release notes and docs need to be updated.
Finally, if we agree this is the way to go, it'd be nice to have some automated tests.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
It seems (I used git history to confirm) that FlatList/VirtualizedList have ([since the begining](https://github.com/facebook/react-native/blame/c13f5d48cfe3e7c0f6c6d0b745b50a089d6993ef/Libraries/Lists/VirtualizedList.js#L79)) a `disableVirtualization` prop.
SectionList ([since it's begining](https://github.com/facebook/react-native/blame/abe737fe746406533798f9670e8e243cb18d5634/Libraries/Lists/VirtualizedSectionList.js#L98)) have a `enableVirtualization` prop, but since SectionList is VirtualizedSectionList which use VirtualizedList, this prop probably never did something. This fix just rename the prop properly so it can have an effect on the underlying VirtualizedList when you use a SectionList.
Since props are spread it's kind of working already, but the flow annotation are wrong (so it tells you it won't work/ you can't use it) which sucks.
(NB: I am doing this since I was trying to use a SectionList with react-native-web & server side rendering to get the all list, you can laugh).

Summary:
SectionList accesses items outside of the array bounds.
This was discovered when using mobx, which warns you: `[mobx.array] Attempt to read an array index (${index}) that is out of bounds`. This is because `section.data[itemIndex + 1]` goes beyond array length.
This PR adds an array length check and simplifies the code a bit to avoid repetitive `this.props.`
