George Zahariev f392ba6725 Codemod {...null} to {} in xplat/js
Summary:
Now that [exact_empty_objects has been enabled](https://fb.workplace.com/groups/flowlang/posts/1092665251339137), we can codemod `{...null}` to `{}` - they are now equivalent.

1) Run my one-off jscodeshift codemod
2) `scripts/flow/tool update-suppressions .` (as some suppressions move around due to the change)

Rubén Norte 2788ee8ba9 Improve performance logger definition and type safety
Summary:
The way the performance logger is defined now is very unsafe regarding type safety, as all accesses to its properties is untyped (`any`) and it uses several `mixed` types in cases that could be more refined.

This migrates the creation of performance loggers to instances of a class to improve its type safety. If there's an impact in performance, it's expected to be positive.

[Internal][Added] - Change signature of `addTimestamp` for IPerformanceLogger and rename old implementation to addTimeAnnotation

Adding this because there is no current ability to add a timespan to our perf logging with pre-defined start and end timestamps. The naming is a bit confusing because the current implementation of `addTimespan` in FB doesn't add a timespan, it adds an annotation of duration. We rename the old implementation to `addTimeAnnotation/s` and update `addTimespan` to suit our needs.

Dan Reynolds d544fa20b7 add support for stringifying error object messages to stringifySafe (#25723)
Summary:
Error objects logged as part of the arguments to `console.error` such as from [rejected es6 promises](https://github.com/zloirock/core-js/blob/v2/modules/es6.promise.js#L110) contain the error that the user would want to see as the error object's message, but is not captured by `stringifySafe`. Here we modify it to if the logged value is an error object print the error similar to chrome:

```
const error = new Error('error');
stringifySafe(error); // Error: error
```

Versus the current behavior which does not recognize the error type and instead tries to stringify the it as an object:

```
JSON.stringify(new Error('error')) // "{}"
```

Summary:
This diff adds a testing screen dev route to the facebook app for testing generated view configs

It's not pretty (i have 0 tetra experiance) but it gets the job done

There are three cases handled:
- No generated config �
- Invalid generated config (useful for dev) �
- Valid generated config �

On the description page we:
- Redbox it it's invalid (this could be used to redbox test all host components)
- Show diffs of the view config properties
- List all of the generated config properties
- List all of the native config properties

Using this tool, it's easy to see what the current config on native is, add correct flow types for the generated config, and validate the generated config

Coming later: adding all of the native configs to the list (will probably need filtering)

James Ide 0ee5f68929 Migrate "Libraries" from Haste to standard path-based requires (sans vendor & renderers) (#24749)
Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.

I was looking at the coverage report of the JavaScript code in the `Libraries` folder, and found some of the modules and functions to be (partially) untested. I believe that adding tests to them would formally capture their behaviour and avoid future regressions. In this PR, I've added some unit tests for 3 utility components.

Perhaps a more general question: Are these kinds of PRs appreciated? I'd be interested in submitting more of them in the future.

empyrical d6c8f189e7 Introduce 'setAndForwardRef' helper function (#21823)
Summary:
This PR introduces a new helper function called `setAndForwardRef`. It is intended to help with moving components that depend on `NativeMethodsMixin` off of `createReactClass`.

It allows for classes that depend on having a ref to a native component to be able to also forward the native component ref to user code.

Usage is like this:

```js
class MyView extends React.Component {
  _nativeRef = null;
  _setNativeRef = setAndForwardRef({
    getForwardedRef: () => this.props.forwardedRef,
    setLocalRef: ref => {
      this._nativeRef = ref;
    },
  });
  render() {
    return <View ref={this._setNativeRef} />;
  }
}
const MyViewWithRef = React.forwardRef((props, ref) => (
  <MyView {...props} forwardedRef={ref} />
));
module.exports = MyViewWithRef;
```

Keith Brown 02d1bcc047 Modified deepFreezeAndThrowOnMutationInDev to use Object.prototype.ha… (#19598)
Summary:
This PR fixes a bug in `deepFreezeAndThrowOnMutationInDev` which did not take into account that objects passed to it may have been created with `Object.create(null)` and thus may not have a prototype. Such objects don't have the methods `hasOwnProperty`, `__defineGetter__`, or `__defineSetter__` on the instance.

I ran into an unrecoverable error in React Native when passing this type of object across the bridge because `deepFreezeAndThrowOnMutationInDev` attempts to call `object.hasOwnProperty(key)`, `object.__defineGetter__` and `object__defineSetter__` on objects passed to it. But my object instance does not have these prototype methods.

Changes:
* Defined `Object.prototype.hasOwnProperty` as a `const` (pattern used elsewhere in React Native)
* Modified calls to `object.hasOwnProperty(key)` to use `hasOwnProperty.call(object, key)` (Per ESLint rule [here](https://eslint.org/docs/rules/no-prototype-builtins))
* Modified calls to deprecated methods `object.__defineGetter__` and `object.__defineSetter__` to instead use `Object.defineProperty` to define get and set methods on the object. (Per guidance on [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/__defineGetter__))
* Added a new test to `deepFreezeAndThrowOnMutationInDev-test` to verify the fix.

I tried to create a reproducible example to post to Snack by passing prototype-less objects to a `Text` component, in various ways, but they appear to be converted to plain objects before crossing the bridge and therefore they do not throw an error.

However, I was able to create a new test to reproduce the issue. I added the following test to `deepFreezeAndThrowOnMutationInDev-test`:

```JavaScript
it('should not throw on object without prototype', () => {
    __DEV__ = true;
    var o = Object.create(null);
    o.key = 'Value';
    expect(() => deepFreezeAndThrowOnMutationInDev(o)).not.toThrow();
  });
```

The changes in this PR include this new test.

ESLint test produced no change in Error count (3) or Warnings (671)
