Summary:
This is a followup for https://github.com/facebook/react-native/pull/12088 and implements the scrolling to end on Android natively rather than sending a large scroll offset from JS.
This turned out to be an OK amount of code, and some reduction in the amount of JavaScript. The only part I'm not particularly happy about is:
```
// ScrollView always has one child - the scrollable area
int bottom = scrollView.getChildAt(0).getHeight() + scrollView.getPaddingBottom();
```
According to multiple sources (e.g. [this SO answer](http://stackoverflow.com/questions/3609297/android-total-height-of-scrollview)) it is the way to get the total size of the scrollable area, similar to`scrollView.contentSize` on iOS but more ugly and relying on the fact the ScrollView always has a single child (hopefully this won't change in future versions of Android).
An alternative is:
```
View lastChild = scrollLayout.getChildAt(scrollLayout.getChildCount() - 1);
int bottom = lastChild.getBottom() + scrollLayout.getPadd

Summary:
== What ==
Changing the `JSBundleLoader` API, to remove `String getSourceUrl()`, instead `JSBundleLoader.loadScript` now returns the source URL it loaded.
This change has a knock-on effect: We can no longer populate `SourceCodeModule` when we construct it, because at that time, we do not know the source URL.
In order to solve this I have made the following changes:
- Added `CatalystInstance.getSourceURL()`, to return the source URL from the instance after the JS Bundle has been loaded, or `null` otherwise.
- Removed `ReactInstanceManager.getSourceUrl()`, because its only purpose was to populate `SourceCodeModule`.
- Also removed `ReactInstanceManager.getJSBundleFile()` because it was only being used in a test confirming that the `ReactInstanceManager` knew its bundle file as soon as it was constructed, which is no longer necessarily true.
- Initialise `SourceCodeModule` with the `ReactContext` instance it belongs to.
- Override `NativeModule.initialize()` in `SourceCodeModule` to fetch the source URL. When the `SourceCodeModule` is constructed, the context does not have a properly initialised `CatalystInstance`, but by the time we call initialise on it, the `ReactContext` has a `CatalystInstance` and that in turn has a source URL.
== Why ==
The reason for this change is that it allows us to add implementations of `JSBundleLoader`, that cannot determine their source URL until after having performed a load successfully. In particular I plan to introduce `FallbackJSBundleLoader` which will try to load from multiple sources in sequence stopping after the first successful load. As load failures could happen for a variety of reasons, we can't know what the true source URL is without performing the load.

Summary:
Currently, < WebView > allows you to pass JS to execute within the view. This works great, but there currently is not a way to execute JS after the page is loaded. We needed this for our app.
We noticed that the WebView had messaging support added (see #9762) . Initially, this seemed like more than enough functionality for our use case - just write a function that's injected on initial load that accepts a message with JS, and `eval()` it. However, this broke once we realized that Content Security Policy can block the use of eval on pages. The native methods iOS provide to inject JS allow you to inject JS without CSP interfering. So, we just wrapped the native methods on iOS (and later Android) and it worked for our use case. The method injectJavaScript was born.
Now, after I wrote this code, I realized that #8798 exists and hadn't been merged because of a lack of tests. I commend what was done in #8798 as it sorely solves a problem (injecting JS after the initial load) and has more features than what I'

used when handling touch to figure out whether we should intercept touch (i.e.
a flat Node is catching the draw), or let Android handle touch (i.e. a Node
mounted to a View will handle the touch).
This patch modifies the list of NodeRegions to exclude any Nodes that draw
nothing at all. These Nodes, having no draw output, are effectively layout
containers used to group items, so they shouldn't handle touch.

This could be breaking if:

The setters now no-op for virtual nodes (I unfortunately couldn't remove them completely -- see the comment on LayoutShadowNode), but the getters will NPE. If you see these NPE's, you should almost definitely be using your own datastructure instead of a CSSNode as virtual nodes will not participate in the layout process (and the CSSNode is then behaving just as a POJO for you).
I do not anticipate this to be breaking for anyone, but am including breaking in the commit message since this is a change in API contract.

Summary:
In Nodes, we added logic when we dropped a view to also pass the
parent, so we could tell the parent that \"hey, this view is now dropped\"
so that it can be released. While this is fine, there are some crashes due
to the fact that the root node is not being found when we drop the child.
I've spent a lot of time thinking about how this could happen, and the only
plausible explanation I can come up with is that we first detach all views
from the root, then drop the root, and then drop one of the children that
was detached. I can't think of a good way why this would happen.
In the interest of protecting from this crash, this patch adds a check as to
whether or not the id of the parent is that of a root id, and, if so, it
doesn't run the logic that tells this view that this view was removed.
This should be safe, because the root most view should not have clipping
enabled (since it's a vanilla view group as opposed to a scrolling view).

This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Reviewed By: sriramramani
Differential Revision: D3904721
Summary:
This fixes a crash for the case when we try to drop a view that has already been dropped.
**The Problem**
We got reports of a crash (t12912526) that occurs when the resolveViewManager method can't resolve a ViewManager for a View being dropped.
Investigating this, one thing in common between all the stack traces for this is that dropView is called from line 210 of FlatNativeViewHierarchyManager. This part of the code is specifically the part we added to remove strong references to any clipped children (from views that have subview clipping enabled).
So this is a problem specifically with Nodes and clipSubviews, which brings up some questions:
**when can this happen?**
The only situation this can possibly happen is when we drop a child (which is clipped) followed by dropping its parent in the same cycle. Consider a tree where each view only has one child, such as: A - B - C - D. This crash would happen if D is clipped, and we removed it, followed by removing any of its parents in the same frame.
**if the removes happen in different frames, does this bug occur?**
No - the reason is that before we execute the DropView operations, we run through StateBuilder, which traverses the shadow tree and marks updates, thus removing the view going away (such that the delete in the next frame doesn't try to re-delete it).
So why doesn't this happen when we're dropping in the same frame? The reason is that manageChildren (where this all starts) asks to remove some views. We handle this by removing said Nodes and their children from the shadow tree. Consequently, when StateBuilder iterates over the shadow tree, it can't do the right thing because said nodes no longer exist.
As a more concrete example, consider A - B - C - D again, and consider that both D and B are removed. StateBuilder only sees A, and realizes that it now has 0 children (whereas before it has 1), so it removes B from its children. However, this process isn't recursive, so C never gets cleaned up.
**why doesn't this happen with Nodes without clipping containers?**
The answer to this is that NativeViewHierarchyManager's dropView method checks the existance of each child before deeply dropping that child and its subtree. So in this case, we drop D and all its children, and when we come to drop B, we try to drop C (which exists) and then its children (D, which doesn't exist because we already dropped it, so we ignore it).
**why doesn't this happen with non-Nodes?**
The reason is that non-Nodes handles removes differently - every remove is enqueued in a call to NativeViewHierarchy's manageChildren, which explicitly asks the parent to remove said child. Consequently, we never try to remove a child that is already removed.
**Fix**
The initial fix was to check whether or not the view exists, but this updated patch just does the right thing at drop time - i.e. whenever a view is dropped, we notify the parent of this fact so that it can clear the reference from clipped views.
**One last Note**
There are two reasons for switching `super.dropView` to `dropView` - first, the comment is only partially correct - calling `super.dropView` will avoid looking at clipped children (as an aside, that could cause a leak in the case of nested clipping subviews), but will look at clipped grandchildren, because of the super class's iteration across the set of children.
