Summary:
Modules which call JS methods directly, or use `sendDeviceEventWithName:`, can trigger effects in JS without ever being referenced from the JS code. This breaks some assumptions in my earlier diff about when modules can be lazily loaded.
Pending a better solution, I've put explicit `init` methods in these modules to ensure they are eagerly initialized (the downside to this is that they'll still be initialized even if they are never used).

Summary:
Previously, if a module implemented `setBridge:` we assumed that it needs to be initialised on the main thread. This assumption was not really warranted however, and it was a barrier to deferring module initialization.
This diff tweaks the rules so that only modules that override `init` or `constantsToExport**` are assumed to require main thread initialization, and others can be created lazily when they are first used.
WARNING: this will be a breaking change to any 3rd party modules that are assuming `setBridge:` is called on the main thread. Those modules should be rewritten to move any code that requires the main thread into `init` or `constantsToExport` instead.
`**` We will also be examining whether `constantsToExport` can be done lazily, but for now any module that uses it will still be created eagerly when the bridge starts up.

Summary:This adds support for delete view animations in LayoutAnimation for iOS. It supports the same properties as the create animation (alpha, scale).
This allows making simple animations when removing a view which is normally hard to do in React since we need to not remove the view node immediately.
**Test plan**
Tested add/removing views in the UIExample explorer with and without setting a LayoutAnimation. Also tested that the completion callback still works properly. Tested that user interation during the animation is properly disabled.
I also plan to work on improving the doc for LayoutAnimation as well as making this PR for android too.

Summary:Hey,
I have been going through some UIAlert related issues in the repo trying to fix them, and one of the steps to start reproducing them was to put `Alert.alert()` call right inside `componentDidMount`.
However, I've started noticing strange bugs as long as I didn't set 1second timeout.
Started digging in deeper, and I've noticed the `UIAlert` gets attached to the `RCTWindow()` mainViewController.
However - since RCTDevLoadingView adds a `keyWindow`, that is the window that will be returned at the time of the call and the window `UIAlert` will be attached to.
To visualise that better - you can take a look at these two frames when app is being loaded:

Summary:All UIManager operations that affect the view hierarchy are executed via the `addUIBlock:` method, which queues them up to be executed after layout has been completed on the shadow queue.
One of the most expensive view operations is view creation, but since this doesn't actually depend on layout, there's no reason to delay it until the shadow operations have finished.
This diff modifies the `createView` method to dispatch view creation directly to the main thread instead of adding it to the UIBlock queue. This seems to result a measurable improvement in TTI.

Summary:If you're working on an app that needs to support landscape, reloading the app causes the iPhone simulator to reset its orientation to portrait every time the `RCTDevLoadingView` shows up. This is because it sets the root VC to `RCTModalHostViewController`, which currently supports only portrait orientations on iPhone. Changing the root view to a vanilla `UIViewController` fixes the issue.
**Steps to Reproduce**
1. Create a blank RN project: `react-native init RNTest`
2. Open it up and run it.
3. Rotate to landscape `Cmd+Right Arrow`.
4. Reload by pressing `Cmd+R`.
**Expected**
The simulator stays in landscape mode.
**Actual**
The simulator goes back to portrait.

Summary:Because the source of truth for backgroundColor is the shadow view, it's possible for the default RCTView backgroundColor to get overwritten by the current shadowView backgroundColor when the view is first created. This overridden value will then be used as the default whenever the background color is reset, which may not be be appropriate for other components that use RCTView.
This diff fixes the bug by ensuring that the view props (and therefore the default color) are set *before* the background color is propagated from the shadowView.

Summary:The UICollectionView example is actually my use-case, which is discussed in a
bit more detail [here](https://github.com/alloy/ReactNativeExperiments/issues/2).
----
This is useful when wrapping native iOS components that determine their
own suggested size and which would be too hard/unnecessary to replicate
in the shadow view. For instance a `UICollectionView` that after layout
will update its `contentSize`, which could be used to suggest a size to
the shadow view.
The reason for adding it to -[RCTShadowView setFrame:] is mainly so it
can be used via the existing -[RCTUIManager setFrame:forView:] API and
because it might not be a feature you want to expose too prominently.
An origin of `{ NAN, NAN }` is used as a sentinel to indicate that the
frame should be used as a size suggestion. The size portion of the rect
may contain a `NAN` to skip that dimension or a suggested value for the
dimension which will be used if no explicit styling has been assigned.
Examples:
* Without any expl

`- [RCTBridgeTests testHookRegistration];`

Also, the `RUN_RUNLOOP_WHILE()` macro did not actually assert when timing out, and the logic in `- [RCTBridgeTests tearDown];` was broken in such a way that tests would always take 5 seconds to run (and then timeout silently). This adds an assertion, and removes the broken nil check for `jsExecutor`.

Summary:The `uiBlockToAmendWithShadowViewRegistry:` is called on every single view manager, on every single layout pass. This causes all view managers to be eagerly intiialized, even if not being used.
In practice very few modules actually use this method, so by checking if the method is implemented before calling it, we can eliminate most of this work.
(Hopefully in future we can get ride of this method altogether, but right now it's integral to the way that text layout is implemented).

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code
