We were executing all the updateBlocks for every frame that was updated in the UI flush. This would quickly give you an explosive number of block calls when loading complex views.
This update block is only really used by text to propagate padding, even though the actual insets are mostly just 0.

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

This diff adds code to catch those exceptions and convert to an error. Also, if no error handling is in place, RCTJSONStringify will now display a redbox, and attempt to recover by sanitizing the JSON data and retrying.

Ok, so this started as fixing #5273 but ended up getting a little more complicated. 😄
Currently, AlertIOS has the following API:
* `alert(title, message, buttons, type)`
* `prompt(title, defaultValue, buttons, callback)`
I've changed the API to look like the following:
* `alert(title, message, callbackOrButtons)`
* `prompt(title, message, callbackOrButtons, type, defaultValue)`
I know that breaking changes are a big deal, but I find the current alert API to be fairly inconsistent and unnecessarily confusing. I'll try to justify my changes one by one:
1. Currently `type` is an optional parameter of `alert`. However, the only reason to change the alert type from the default is in order to create one of the input dialogs (text, password or username/password). So we're in a weird state where if you want a normal text input, you use `prompt`, but if you want a password input you use `alert` with the 'secure-text' type. I've moved `type` to `prompt` so all text input is now done with `pro

By doing this we fix 2 problems:
1. We use the same url, both the first time the simulator starts with Hot Loading disabled (no `hot` attribute), and after HL has been enabled and then disabled ('hot=false'). By doing so, the packager will rebuild more than one bundle as file changes. We could have ignored this attribute on the packager but I'd rather not contaminate the server with it and instead make the clients send only 2 types of URLs.
2. The code on `RCTBatchedBridge.m` that decides whether or not to enable HMR does so by looking at presence of the query string parameter `hot`. If the parameter is present, even when it's false, it will try to enable HL, which is wrong.

Summary:

Most of the time - especially during app startup - when we call UIManager.manageChildren(), we are actually just adding the first set of children to a newly created view.
This case is already optimized for in the JS code, by memoizing index arrays at various sizes, but this is not especially efficient since it is still sending an array of indices with each call that could be easily inferred on the native side instead.
I've added a hybrid native/JS optimization that improves the performance for this case. It's not a huge win in terms of time saved, but benchmarks show improvements in the ~1% range for several of the app startup metrics.

Thanks to the new lazy initialization system for modules, `RCTDidCreateNativeModules` no longer does what the name implies.
Previously, `RCTDidCreateNativeModules` was fired after all native modules had been initialized. Now, it simply fires each time the bridge is reloaded. Modules are created on demand when they are needed, so most of the assumptions about when `RCTDidCreateNativeModules` will fire are now incorrect.
This diff deprecates `RCTDidCreateNativeModules`, and adds a new notification, `RCTDidInitializeModuleNotification`, which fires each time a module a new module is instantiated.
If you need to access a module at any time you can just call `-[bridge moduleForClass:]` and the module will be instantiated on demand. If you want to access a module *only* after it has already been instantiated, you can use the `RCTDidInitializeModuleNotification` notification.

A lot of the core modules have to use private methods in the bridge, specially
since the `RCTBatchedBridge` interface is never exposed. That was leading to a
lot of different private bridge categories spread across different modules,
which makes harder to identify which modules are affected by private API changes.
Replace all the categories with a single private header.

Summary:
A component can be backed by native "node" that can change its internal state, which would result in a new UI after the next layout. Since js has no way of knowing that this has happened it wouldn't trigger a layout if nothing in js world has changed. Therefore we need a way how to trigger layout from native code.
This diff does it by adding methods `layoutIfNeeded` on the uimanager and `isBatchActive` on the bridge.
When `layoutIfNeeded` is called it checks whether a batch is in progress. If it is we do nothing, since at it's end layout happens. If a batch is not in progress we immidiately do layout.
I went with the easiest way how to implement this - `isBatchActive` is a public method on the bridge. It's not ideal, but consistent with other methods for modules.

This diff replaces the RegEx module method parser with a handwritten recursive descent parser that's faster and easier to maintain.
The new parser is ~8 times faster when tested on the UIManager.managerChildren() method, and uses ~1/10 as much RAM.
The new parser also supports lightweight generics, and is more tolerant of white space.
(This means that you now can – and should – use types like `NSArray<NSString *> *` for your exported properties and method arguments, instead of `NSStringArray`).

Summary:

Currently, we wait to invoke `-flushUIBlocks` until the JavaScript batch to native has completed. This means we may be waiting an unnecessarily long time to perform view hierarchy changes and prop changes.
By instead invoking this after each chunk of enqueued UI blocks, we can perform some updates more eagerly, increasing our utilization of the main thread while splitting up the amount of time we spend running upon it.
This shouldn't affect layout, which is still tied to `-batchDidComplete`, so any visual inconsistencies should be limited to prop changes, which seems acceptable for the dramatic improvement in performance.

Summary: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand
