Summary:
<!-- Explain the **motivation** for making this change. What existing problem does the pull request solve? -->
I have used RN for a long time, and for all this time, crash reporting has been less great than native development crash reporting. At some point, companies like sentry, bugsnag and a bunch of others started supporting sourcemaps for js crashes in RN, which helped a lot.
But native crashes were (and still are) much harder to diagnose.
..Until now :D
I have make a repo of a sample RN app, included this PR in it, and some code and screenshots to help.
The repo is [here](https://github.com/pvinis/react-native-project-with-crash-heaven-pr).
I was trying to get good crash reports from native crashes in iOS for a looong time. I spoke with people in sentry, in bugsnag and more, and I could not get this solved. There was no clear way to get the **native** crashed to display correctly.
I made two repos here, one for [sentry](https://github.com/pvinis/SentryBadStack) and one for [bugsnag](https://github.com/pvinis/BugsnagBadStack), demonstrating the correct js handling and the bad native handling.
After all this, and talks with their support, twitter etc, I investigated further, on **why** this was happening. I thought there must be some reason that native crashes look bad in all the tools, and in the same way. Maybe it's not their fault, or up to them to fix it, or maybe they didn't have the experience to fix it.
In a test project I created, I checked what's up with the `RCTFatalException`, and I found out that the React Native code is catching the `NSException`s that come from any native modules of a RN app and converting it into an string and sending it to `RCTFatal` that created an `NSError` out of that string. Then it checks if the app has set a fatal error handler and if not, goes ahead and throws that `NSError`.
The problem here is that `NSException` has a bunch more info that the resulting `NSError` is missing or is altering. Turning the callstack into a string renders crash reporting tools useless as they are missing the original place the exception was thrown, symbols, return addresses etc. In both repos above it can be seen that both tools were thinking that the error happened somewhere in the `RCTFatal` function, and it did, since we create it there, losing all the previous useful info of the original exception. That leaves us with just a very long name including a callstack, but very hard to actually map this to the code and dsym.
I added a fatal exception handler, that mirrors the fatal error handler, as the error handler is used around React Native internal code.
Then I stopped making a string out of the original `NSException` and calling `RCTFatal`, and I simply throw the exception. This way no info is lost!
Finally, I added some code examples of native and js crashes and added a part in the `RNTester` app, so people can see how a js and a native error look like while debugging, as well as try to compile the app in release mode and see how the crash report would look like if they connect it to bugsnag or sentry or their tool of choice.
I have attached some images at the bottom of this PR, and you can find some in the 3 repos I linked above.
[iOS] [Fixed] - Changed the way iOS native module exceptions get handled. Instead of making them into an `NSError` and lose the context and callstack, we keep them as `NSException`s and propagate them.
[General] [Added] - Example code for native crashes in iOS and Android, with buttons on RNTester, so developers can see how these look when debugging, as well as the crash reports in release mode.

Summary:
This adds new functionality to the `Image` component by allowing you to retrieve the width and height of an image just like you'd do with [`Image.getSize`](https://facebook.github.io/react-native/docs/image.html#getsize) but _with_ the ability to provide headers to your request.
Why would you need this you ask? Well, imagine that you have an image that you're loading into your `Image` component that is protected and you get access by using a token in a header (or something similar). That would work. However, getting the dimensions isn't possible since you can't provide those same headers.
This is something that is bothering me when using a third-party library (https://github.com/archriss/react-native-image-gallery) and instead of implementing this just for that single library I imagined that it would be useful for anyone else that needs to get the image dimensions before displaying it.

- changing "interval" example from "time-only" to "datetime" because there's a known bug that prevented the previous example from working https://github.com/facebook/react-native/issues/9566
- splitting the label to two: one for date and other one for time, so that we can match the date only when we test "date" mode only

Summary:
Initially if a `react-native-web` project were to use a library that required internals `expo/webpack-config` would polyfill those internals. This `Platform.web` was used for cases where `react-native` modules needed other internal `react-native` modules, ex: `Animated/src/AnimatedEvent -> Renderer/shims/ReactNative -> Renderer/oss/ReactNativeRenderer-dev -> Core/InitializeCore -> Devtools/setupDevtools -> WebSocket/WebSocket -> Utilities/Platform`
The consensus is that if any `react-native` library references a `react-native` internal (ex: `react-native/*`), it should continue to throw errors. We've removed the use of internals from all of the Unimodules, `react-navigation`, and `react-native-gesture-handler`. This covers a wide enough area for a lot of projects to get web support.

Summary:
This change fixes https://github.com/facebook/react-native/issues/23645.
The issue is that the `YGMarker.cpp`, `YGValue.cpp`, `YGConfig.cpp` and `log.cpp` files are already included in the Yoga compilation unit, so including these files in React's compile sources too results in "duplicate symbols" errors when loading React Native with `-force_load` (which behaves slightly differently to `-ObjC` - according to a colleague, "ObjC will scan through each object file in each library and force linking of any object file that contains Objective C code, while force_load will link every object file in a particular staticlib (regardless of whether or not the object file contains Objective C code)").
These changes seemed to be introduced by a few commits:
- D13819111 -> 43601f1a17
- D13439602 -> b5c66a3fbe
- D14123390-> e8f95dc7a1
- D7530369 -> 95f625e151
Perhaps we need to check with the original authors/any C++ experts to confirm if this fix is correct - it compiles for me but I'm not sure what the original intention of these changes was.

Summary:
I measured the performance of UIMananger methods and found that `create` method spends a significant amount of time on preallocating views (around 10 ms on my device). Interestingly, this time was actually spent on dispatching operations on the main thread, not on performing those operations. That makes me think about think about the preallocation problem one more time.
(Here and later I discuss preemptive optimistic preallocation views on iOS, but the issues are more-less applicable for all platforms.)
BTW, what's view preallocation? – In React Native we believe that we can get significant TTI wins instantiating platform views ahead of time while JavaScript thread is busy doing reconciliation and the main one is idle.
So, seems the current approach has those downsides:
* We spend too much time on dispatching only (jumping threads, creation Objective-C blocks, managing them in GCD, incrementing atomic refcountes inside `ShadowView` and so on). That's wasteful.
* We don't have much information during preallocations that can help prepare something to save time in the future. We don't know the future size of the component, so we cannot e.g. pre-draw a border or even allocate memory for a future drawing.
* We pre-allocate to much. At the moment of component creation, we don't know will this component be filtered out by view-flattening infra or not, so we always allocate a view for it. That's ~30% more views that we actually need.
* We don't stop allocating (or dispatching instructions for that) after the recycle pool is already filled in. That's also wasteful.
Why is this so bad and how can we fix it properly?..
I thought about this problem for months. And I think the answer is trivial: We don't know the exact shape of the interface until we finish creating it, and there is no way to overcome this problem on the client side. In the ideal world, the server size (or hardcoded manifest somewhere) tells the renderer (at the moment where we started navigating to it) how many views of which type will some surface use.
And until our world is not so perfect, I think we can get a significant performance improvement doing simple preallocation of 100 regular views, 30 text views, and 30 image views during rendering the first React Native surface. So I hardcoded that.

Summary:
Right now we rely on the Paper UIManager to update animated node graphs - this hooks us into `RCTSurfacePresenter` in the same way so we are no longer reliant on Paper. Should also help with complex ordering corner cases with pre vs. post operations and restoring defaults when nodes are removed. More info:
https://github.com/facebook/react-native/pull/11819/files
Note that we don't have a way to differentiate animation nodes related to fabric views vs. paper views, so if paper and fabric are both rendering updates simultaneously it's possible they could get processed by the wrong callback. That should be very rare, rarely cause problems even if it does happen, and won't be a problem at all in a post-Paper world.

Summary:
We currently rely on the Paper UIManager calling `uiManagerWillPerformMounting` to flush the animated operations queue, which includes starting and stopping animations. This mostly works right now because Fabric always starts after Paper, but sometimes Paper doesn't fire `uiManagerWillPerformMounting` for a while, which can delay an animation starting.
To fix this, I force a flush of the queues on the UIThread whenever start or stop is called. This should be safe because the order of animation operations is still preserved, and start/stop are (almost?) always called in dedicated event handler loops, so any other updates like changing the way nodes are attached should already have been processed from a previous JS execution loop.
