Summary:
The bug #18374 was caused by the loose condition to execute `stringByReplacingCharactersInRange` in the method `textInputShouldChangeTextInRange` . As a result, `findMismatch` wrongly returning `true` which ends up the Backspace event being fired in another `textInputShouldChangeTextInRange` call in `textInputDidChange`.

export default class App extends Component<Props, State> {
state = {text: '', keys: ''}
render() {
return (
<View style={styles.container}>
<TextInput style={styles.textInput} value={this.state.text} onChangeText={this.onChangeText} onKeyPress={this.onKeyPress}/>
<Button title="Clear" onPress={this.onClear}/>
<Text>Text: {this.state.text}</Text>
<Text>Keys: {this.state.keys}</Text>

Summary:
This PR makes sure that changing the `keyboardType` props of `<TextInput>` is reflected while the text field has focus. It is something that is also discusses in #13782. The workaround mentioned in that issue using `key` causes the TextInput to re-render itself which has some undesired side-effects.
Fixes#13782
```javascript
export default class KeyboardTypeApp extends Component {
state = { keyboardType: 'default' };
toggleKeyboardType = () => {
this.setState({
keyboardType: this.state.keyboardType === 'default' ? 'numeric' : 'default'
});
}
render() {
return (
<View style={{ padding: 40 }}>
<TextInput autoFocus value="Press Toggle :)" keyboardType={this.state.keyboardType} />
<Button title="Toggle" onPress={this.toggleKeyboardType} />
</View>
);
}
}
```

Summary:
Thank you for sending the PR! We appreciate you spending the time to work on these changes.
Help us understand your motivation by explaining why you decided to make this change.
React Native provides an implementation of the Web "Console" API, which is a powerful mechanism for debugging and analyzing RN apps. However, one subset of the Console API that RN does not provide is the "grouping" functions, namely `console.group` and `console.groupEnd`. These functions provide a useful way to see how an application behaves within a different parts of an application hierarchy.
I modified the "RNTester" app to create a console group each time an example is tapped, and the group is ended when the "Back" button is tapped. Here is an example of the grouping as seen in the Xcode console.

Summary:
Currently on iOS and Android focus/blur events trigger onPressIn/onPressOut. Based on discussions with people are several companies who use react-native we're proposing instead triggering new events onFocus/onBlur. Initial discussion on Slack with some from the core team on Slack seemed positive.
Couple reasons:
* The current API behavior overloads onPressIn/onPressOut. That means on platforms like react-native-web, if focus/blur support was added (as we're hoping for), even though onPressIn/onPressOut would be useful as the name describes, you wouldn't be able to distinguish between it and browser element focus/blur events.
* The names aren't as self-documenting/intuitive as onFocus/onBlur, especially for react-dom users.
There aren't any current tests around this, but I intend to add them if we solidify the API.
There's also an option question on the transition--do we deprecate the existing API with a warning? This PR just deprecates them, though it will on any TV platform when something becomes focused regardless of whether they use the API or not. This isn't ideal. It's not clear if there are alternatives or if just right away breaking the API for TV users is the correct solution, if we can get consensus between the few parties who are using it.

I'm interested to hear counter points or prior discussions.

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)

Summary:
While investigating an issue about blobs (https://github.com/facebook/react-native/issues/18223), I noticed that the fetch polyfill (https://github.com/github/fetch) uses blobs as the response type by default if the module is available (https://github.com/github/fetch/blob/master/fetch.js#L454). This surfaced some issue with the blob implementation on iOS that has since been fixed.
However after further review of the fetch polyfill and the way Blobs work in RN, I noticed a major issue that causes blobs created by fetch to leak memory. This is because RN blobs are not deallocated automatically like in the browser (see comment https://github.com/facebook/react-native/blob/master/Libraries/Blob/Blob.js#L108) and the fetch polyfill does not deallocate them explicitly using the close method.
Ideally we should implement automatic blob cleanup when the instance is garbage collected but implementing that is probably somewhat complex as it requires integrating with JSC. For now I suggest disabling the default handling of requests as blobs in the fetch polyfill. This will mitigate the issue for people not using Blobs directly. I'm not sure how well documented the Blob module is but we should make it clear that they currently require explicit deallocation with the close method for people using them directly.
Run a simple http request using fetch and make sure it does not use the Blob module anymore.
