Summary:
## Context
Every time we call RCTNetworking.sendRequest(), we [set up six event listeners inside XMLHttpRequest](https://fburl.com/diffusion/85k6ou5w) by calling RCTNetworking.addListener(). Seeing how RCTNetworking.addListener() is implemented, each call results in two async NativeModule call: [one to addListener()](https://fburl.com/diffusion/ng21jek6), and [another to removeEventListener()](https://fburl.com/diffusion/nua3y973).
For RCTNetworking, both of these NativeModule calls are unnecessary, as explained in D24272663 (https://github.com/facebook/react-native/commit/dabca52f77799bcdedb6b0ec44b1f6297483a46d)
> RCTNetworking.startObserving and RCTNetworking.stopObserving don't exist. The main purpose of RCTEventEmitter.addListener is to call these methods, and increment the _listeners counter, so that we can start dispatching events when _listeners > 0. In D24272560 (https://github.com/facebook/react-native/commit/82187bfb6b54fdffc5dadaa56e8bf97d2209708a), I made RCTEventEmitter dispatch events even when _listeners <= 0. This is sufficient for us to stop calling these two RCTNetworking methods entirely.
Therefore, this experiment gets rid of on average 6-8 NativeModule method calls for every network call we make in React Native on iOS.

Summary:
All NativeModules that used to use the bridge to require other NativeModules now require other NativeModules via the Venice-compatible RCTModuleRegistry abstraction. Therefore, we can safely get rid of synthesize bridge = _bridge from them.
## How did I generate this diff?
1. Search for all NativeModules that have `synthesize bridge =`
2. Remove the `synthesize bridge = _bridge` from each NativeModule, and if it doesn't contain `_bridge`, `setBridge:`, or `elf.bridge`, add it to this codemod.

Summary:
## Rationale
For every 1 call to RCTNetworking.sendRequest, we execute 6 calls to RCTNetworking.addListener. This is followed by at least one call to RCTNetworking.removeListeners. Aside from incrementing and decrementing the `_listeners` integer, these two methods accomplish nothing else: RCTNetworking doesn't implement the `startObserving` and `stopObserving` methods.
This diff makes RCTEventEmitter dispatch events without looking at the listeners integer. In the future, this will allow us to stop making these ~8 unnecessary NativeModule calls for every Network request we send.

Summary:
This diff ended up being a bit more complicated than I anticipated, since the source files in `ReactInternal` were depending on `RCTEventDispatcher`. I made the following changes:
1. Make `RCTEventDispatcher` a `protocol`, keep it in `ReactInternal`.
2. Rename the `RCTEventDispatcher` NativeModule to `RCTEventDispatcherModule`, make it conform to the `RCTEventEmitter` `protocol`, and move it to `CoreModules`.
3. Where necessary, replace categories of `RCTEventDispatcher` with functions.

This PR removes most of the tvOS remnants in the code. Most of the changes are related to the tvOS platform removal from `.podspec` files, tvOS specific conditionals removal (Obj-C + JS) or tvOS CI/testing pipeline related code.
In addition to the changes listed above I have removed the deprecated `Platform.isTVOS` method. I'm not sure how `Platform.isTV` method is correlated with Android TV devices support which is technically not deprecated in the core so I left this method untouched for now.

Summary:
Microsoft’s RN for macOS fork supports the Hermes engine nowadays https://github.com/microsoft/react-native-macos/pull/473. As a longer term work item, we’ve started moving bits that are not invasive for iOS but _are_ a maintenance burden on us—mostly when merging—upstream. Seeing as this one is a recent addition, it seemed like a good candidate to start with.
As to the actual changes, these include:
* Sharing Android’s Hermes executor with the objc side of the codebase.
* Adding a CocoaPods subspec to build the Hermes inspector source and its dependencies (`Folly/Futures`, `libevent`).
* Adding the bits to the Xcode build phase script that creates the JS bundle for release builds to compile Hermes bytecode and source-maps…
* …coincidentally it turns out that the Xcode build phase script did _not_ by default output source-maps for iOS, which is now fixed too.
All of the Hermes bits are automatically enabled, on macOS, when providing the `hermes-engine-darwin` [npm package](https://www.npmjs.com/package/hermes-engine-darwin) and enabling the Hermes pods.

Summary:
## Problem
For some reason, D20831545 broke the `use_frameworks!` build of RNTester.
## Building RNTester
```
pushd ~/fbsource/xplat/js/react-native-github/RNTester && USE_FRAMEWORKS=1 pod install && open RNTesterPods.xcworkspace && popd;
```
## Error
I built RNTester locally, and the error was this:
```
Undefined symbols for architecture x86_64:

```
## Fix
It looked like libraries that depend on "ReactCommon/turbomodule/core" weren't linking to JSI correctly. So, I modified all such Podspecs to also depend on "React-jsi":
```
arc rfr ' s.dependency "ReactCommon/turbomodule/core", version' ' s.dependency "ReactCommon/turbomodule/core", version\n s.dependency "React-jsi", version'
```
This seemed to do the trick. In buck, we'd fix this problem using exported_dependencies. I skimmed through cocoapods, and couldn't find such a configuration option there. So, I guess this will have to do?

Summary:
In `XMLHttpRequest`, if the responseType is `Blob`, but the response is an empty string, we return `null` from `XMLHttpRequest.prototype.response()`. Instead, we should return an empty Blob. This is the behaviour on the web. To demonstrate, run the following HTTP server with Node:
## server.js
```
const http = require('http');
const server = http.createServer();
server.on('request', (request, response) => {
if (request.url.includes('img.png')) {
console.log('sending image');
response.end('');
return;
}
response.end('Hello World!');
});
server.listen('9000');
```
Then, open up a web browser to `http://localhost:9000`, and type the following in the console:
```
var oReq = new XMLHttpRequest();
oReq.open('GET', 'http://localhost:9000/img.png', true);
oReq.responseType = 'blob';
oReq.onload = function(oEvent) {
var blob = oReq.response;
console.warn(blob);
};
oReq.onerror = function(error) {
console.warn('Error!');
};
oReq.send();
```
This warns:
```
Blob {size: 0, type: "text/xml"}
```

Summary:
As part of the fix for https://github.com/facebook/react-native/issues/25349 I added `s.static_framework = true` to each podspec in repo (see https://github.com/facebook/react-native/pull/25619#discussion_r306993309 for more context).
This was required to ensure the existing conditional compilation with `#if RCT_DEV` and `__has_include` still worked correctly when `use_frameworks!` is enabled.
However, fkgozali pointed out that it would be ideal if we didn't have this requirement as it could make life difficult for third-party libraries.
This removes the requirement by moving `React-DevSupport.podspec` and `React-RCTWebSocket.podspec` into `React-Core.podspec` as subspecs. This means the symbols are present when `React-Core.podspec` is built dynamically so `s.static_framework = true` isn't required.
This means that any `Podfile` that refers to `React-DevSupport` or `React-RCTWebSocket` will need to be updated to avoid errors.
## Changelog

Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in https://github.com/facebook/react-native/pull/25393#issuecomment-508457700. If accepted, it will fix https://github.com/facebook/react-native/issues/25349.
It builds on the changes I made in https://github.com/facebook/react-native/pull/25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.
The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .
There are still a few breaking changes which I hope will be acceptable:
- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511040967.
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.
Still to do:
- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in https://github.com/facebook/react-native/issues/25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by https://github.com/facebook/react-native/pull/25619/commits/33573511f02f3502a28bad48e085e9a4b8608302.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �

Test Plan:
### FB

### Sample Project
Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.
You can see that it works with these steps:
1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`
The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.
### RNTesterPods
`RNTesterPodsPods` can now work with or without `use_frameworks!`.
1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.

Summary:
This PR adds initial support for Project Catalyst a.k.a. UIKitForMac. This is not yet meant for production, but this is enough for RNTester to successfully compile and mostly work :)
Some APIs are not supported on the Mac -- e.g. telephony, and deprecated APIs are removed on Mac ���-- those had to be ifdef'd out via platform checks.
The biggest limitation right now is that I couldn't get Web Socket code to successfully compile, and so there are a lot of temporary platform checks for that , and the RCTWebSocket.xcodeproj is marked as not supporting UIKitForMac. Again -- temporary, until someone with more knowledge knows how to fix this.

## Changelog
[iOS] [Added] - Fixed compilation for macOS (Project Catalyst) -- not meant for production use yet
Pull Request resolved: https://github.com/facebook/react-native/pull/25427
Test Plan:
- Open RNTester/RNTester.xcodeproj with Xcode 10.2, run it like a normal iOS app -- make sure it compiles and runs correctly (no regression)
- Open the same project with Xcode 11 beta 2 (or higher) on macOS Catalina beta, select "My Mac" as device target, and run -- see that it actually compiles and runs. **Note** there are unfortunately some required steps:
- change build configuration to Release (because packager doesn't work correctly yet)
- change development team to yours if Xcode tells you to
- go to RNTester project → Build phases → Link binary with libraries, and change `platforms` for `libRCTWebSocket.a` to `iOS` (without Mac compatibility). I can't commit that change because it breaks compatibility with earlier Xcode versions
The two extra steps for successful compile will disappear once web socket compilation for Catalyst is fixed

Summary:
The old whatwg-fetch module doesn't actually export anything, so we would always hit the `else` condition.
The new whatwg-fetch (3.0.0, introduced in #24418) now exports an ES module. As a result, `whatwg` and `whatwg.fetch` are both truthy but the `module.exports` will end up empty. This breaks the RN fetch module.
This will switch the behavior back to the expected polyfill behavior (calling `require('whatwg-fetch')` and allowing it to polyfill fetch in global scope). The RN fetch module will re-export these globals.
