Summary:
Fixes https://github.com/facebook/react-native/issues/13784
The section footer was only rendered with the last item of the section. However, that meant in sections where no items were rendered, no section footer would be rendered. This patch makes sure that when there are no items the section footer is rendered with the section header in addition to adding tests asserting the existance of section footers in empty lists.
One potential point of contention is whether or not a section separator (as defined by the `SectionSeparatorComponent` prop to `<SectionList>`) should be rendered in an empty list. I did not include a section separator for empty lists, but let me know if you think one should be included. See the test plan below for an image of an empty section rendered without a section separator.
I was also running into a lint error, `no-alert`, in `SectionListExample.js` around line 135 that blocked me from publishing. This error looks to be triggered when the `alert()` global function is called, so to fix the error I added an import for the `Alert` module and called the `alert()` function on that module.
To help debug the `scrollToLocation()` behavior that was modified as a part of this PR I added three buttons (can be seen in the test plan image) which scroll to arbitrary points in the list.

**Motivation**
The ART library is part of the react-native repo, but is not included in UIExplorer and has no native testing. This PR adds the ART library to UIExplorer, adds an example tab for it, and adds a snapshot test.

New snapshot test.

Summary:
There was an edge case where sometimes a view could be added and removed in the same batch so this caused issues because we ran `disconnectAnimatedNodeFromView` before `connectAnimatedNodeToView`. This separates restoring default values from `disconnectAnimatedNodeFromView` so we can run only `restoreDefaultValues` on the pre-operations queue and just do nothing in case the view doesn't exist (it is fine because we know it will be removed immediately).
**Test plan**
Tested that native animations still work properly in RNTester and tested that the edge case crash was fixed.

Summary:
This changeset moves the creation of the transform cache at the top-level of the bundler so that:
* we can use alternative folders, such as the project path itself, that I think will be more robust especially for OSS;
* we can disable the cache completely, that is useful in some cases (for example, the script that fills the global cache).
The reasons I believe a local project path is more robust are:
* there are less likely conflicts between different users and different projects on a single machine;
* the cache is de facto cleaned up if you clone a fresh copy of a project, something I think is desirable;
* some people have been reporting that `tmpDir` just returns nothing;
* finally, it prevents another user from writing malicious transformed code in the cache into the shared temp dir—only people with write access to the project have write access to the cache, that is consistent.

Summary:
This is a simple bugfix. `_updateViewableItems` expects the `data` prop, as it calls `getItemCount` on it. Without this, `onViewableItemsChanged` updates twice for each scroll position, once from `_onScroll` with the incorrect results, and once from `_updateCellsToRender` with the correct results. This means the callback nigh-on unusable.
I simply logged the results of `onViewableItemsChanged` and made sure they were correct.

Summary:
In some cases, `RCTRecursiveAccessibilityLabel` could return an accessibility label that had leading space, trailing space, or multiple spaces between words. This is because it always added a space before adding a label even if the label turned out to be empty.
This is fixed by being stricter about adding spaces.
Found test cases that used to introduce leading space, trailing space, or multiple spaces between words and verified that there aren't any extra spaces after the fix.
```
{/* Used to have leading space */}
<View accessible={true}>
<View />
<View accessibilityLabel='Two' />
<View accessibilityLabel='Three' />
</View>
{/* Used to have 2 spaces between "One" and "Three" */}
<View accessible={true}>
<View accessibilityLabel='One' />
<View />
<View accessibilityLabel='Three' />

{/* Used to have trailing space */}

NativeReadable{Map,Array} classes have convenient to{HashMap,ArrayList}
methods that make it easier to interoperate with existing Java code
from within a ReactNative application (e.g., Native Module)
These changes make these same methods available to any code using
the Readable{Map,Array} interfaces, instead of forcing consumers to
cast their generic instances into the NativeReadable* equivalents
Moving this methods up to the interfaces also makes it easier to
write unit tests for Native Modules - using the JavaOnly{Map,Array}
implementations of Readable{Map,Array} - while still relying on the
to{HashMap,ArrayList} methods
* Write a native module that receives a JSON object as `ReadableMap` and a JSON array `ReadableArray`.
* Print out the result of `toHashMap` and `toArrayList`.
* Make sure `NativeReadable{Map,Array}` works:
* Call the native module's method from JavaScript, passing an `Object` and an `Array`.
* Compare the printed values with the passed content.
* Make sure `JavaOnly{Map,Array}` works:
* Call the native module's method from the Java code and pass a `JavaOnlyMap` and a `JavaOnlyArray`.
* Compare the printed values with the passed content.
**Please advise if there is an automated test suite where I could add a case for this.**

* Internally, we already set up babel before calling into metro-bundler.
* Externally, I moved the setup calls to outside the packager/ folder.
If somebody has a custom integration with RN, they would need to setup babel themselves up until we make the open source split. By the time this is released in open source, an npm version of metro-bundler will be available for use.
Next step: also do this for the worker and remove setupBabel from the metro repo.

Summary:
We are removing support of nesting views inside <Image> component. We decided to do this because having this feature makes supporting `intrinsinc content size` of the `<Image>` impossible; so when the transition process is complete, there will be no need to specify image size explicitly, it can be inferred from actual image bitmap.
And this is the step #0.
<ImageBackground> is very simple drop-in replacement which implements this functionality via very simple styling.
Please, use <ImageBackground> instead of <Image> if you want to put something inside.

Summary:
Working on refactoring error handling in `_loadAsDir` I figured out it was oftentimes problematic to pass on the candidates out of the functions as an array, as in practice there's always a single "candidates" object passed out. Also, using an array prevented nice Flow typing and forced additional invariants to be added. So I replaced that by a return value that explicitely can be either a module, or resolution candidates. That way the semantic is more clear: we don't get any candidates if we did resolve properly, and at the same time we enforce returning candidates if we could not resolve any module.
At first I wanted to just have type `{module: TModule} | {candidate: TCandidate}`, but Flow would hit edge cases, so instead I added a field `type` that make it explicit what is the result of the resolution, and allows Flow to refine the type fully after we test that field. This allows us to remove the extraneous invariants. Also, a nice thing is that at a few places, even if the type of the candididate is different, Flow allows us to return the "resolved" object just as it is, that prevents using more memory and causing more garbage collection than necessary.
Since we're creating more objects with that solution, this will be slightly less performant than returning `Module` objects directly, but I don't think it is worth micro optimizing this at that point. If really we see this to be causing trouble later, I'd try to find solutions such as reusing a pool of objects. Ex. we could pass the result `Resolution` object as argument instead of returning a fresh one, but that would make the code less legible, more complex.
