Summary:
This change aims at replacing SYSTEM_ALERT_WINDOW/OVERLAY API being used for rendering dev support related views on Android (redbox, dev menu, green loading view) with API that does not require any special permission. The permission is still used for displaying perf monitor, although it is no longer requested at app startup but only when perf monitor gets enabled.
This change should not affect the way react native apps work in production environment as in release mode all dev support functionality is disabled.
There are two main reasons why requiring SYSTEM_ALERT/OVERLAY permission for displaying basic dev related windows is problematic:
1) On Android >=6 devices it is required that overlay permission is granted in device settings for apps being side loaded (not installed via play store which is usually the case for apps being developed). Although this setting is not available on some Android devices including Google's stock Android TV version. On such devices App cannot be granted rights to draw in system alert window which cases the app to crash (instead of showing a redbox or dev menu dialog)
2) Some Android device vendors have issues with implementation of `Settings.canDrawOverlays` that always return false (I've seen it on Xiaomi Redmi 4A with Android 6.1). This issue because of the following code in [ReactActivityDelegate.java#L90](1e8f3b1102/ReactAndroid/src/main/java/com/facebook/react/ReactActivityDelegate.java (L90)), results in the overlay permission settings screen popping up every time the app is launched even though the permission has been perviously granted which is extremely annoying. Since this change only require overlay permission for displaying perf monitor we no longer ask for it on startup but only when user switches perf monitor ON.
Test need to be performed on pre Android 6 and post Android 6 devices.
1. Run app with devserver off -> should result in redbox
2. Start packager with --reset-cache flag for the loading bar to be visible for some longer period of time. Then restart the app and see the loading bar show up
3. While the app is running, open dev menu, navigate to "dev settings", test "reload"
4. Modify JS app such that the app crashes, see it display redbox properly. Check if "reload" button works well from the redbox
5. Verify that "Show Perf Monitor" option works as expected. On Android >=6 re-install the app to see it ask for overlay permission at the moment when perf monitor option gets selected.
- SYSTEM_ALERT_WINDOW permission will no longer be required on Android to display Redbox
This change can break things for framework users who provide custom implementation of DevSupportManager interface on Android:
- **Who does this affect**: Owners of apps that use custom implementation of DevSupportManager interface on Android.
- **How to migrate**: Update `create` method of your `DevSupportManager`'s factory to take `ReactInstanceManagerDevHelper` type as a second argument instead of `ReactInstanceDevCommandsHandler`. The interface `ReactInstanceDevCommandsHandler` has been renamed to `ReactInstanceManagerDevHelper` but kept all the methods the same (new method got added). If you were calling one of three methods from `ReactInstanceDevCommandsHandler` interface (`onReloadWithJSDebugger`, `onJSBundleLoadedFromServer` and `toggleElementInspector`) you can call exact same methods directly on `ReactInstanceManagerDevHelper` instance that is being provided in exchange for `ReactInstanceManagerDevHelper `.
- **Why make this breaking change**:
This PR adds a new method to `ReactInstanceManagerDevHelper` called `getCurrentActivity`. In which case the prev name can no longer be justified. The activity is required for some of the DevSupportManager methods in order to start new dialogs and popups so that overlay permission isn't necessary.
- **Severity (number of people affected x effort)**:
Relatively small (perhaps Fb internally is using DevSupportManager abstraction to provide an alternative implementation but since it isn't documented I doubt anyone else uses it). Effort it very low as it boils down to updating uses of interface `ReactInstanceDevCommandsHandler` with `ReactInstanceManagerDevHelper` (all the methods in `ReactInstanceDevCommandsHandler` stays the same)

Summary:
There's a crash-inducing bug with `Image.blurRadius` on Android.
`blurRadius` is specified in JavaScript as a `float`, but it's cast to `int` before being passed to the `IterativeBoxBlurPostProcessor`. However, in `IterativeBoxBlurPostProcessor`, there is an argument precondition requiring the integer `blurRadius` to be non-zero.
Because the `== 0` condition is evaluated on the `float`, it's possible for a `blurRadius` in the range of `(0, 1)` (non-inclusive) to pass the conditional, and then be truncated to `0` and passed as an argument to `IterativeBoxBlurPostProcessor`, which will fail its precondition and crash the app.
This change works in our app, which was previously crashing.

**The fix**: If the API version is less than 18 and we're rendering rounded borders, I disable hardware acceleration. Otherwise, I enable it. I'm going to check to see if this has perf regressions by running a CT-Scan.
With this change, rounded borders render correctly on Android devices running versions of Android between Honeycomb to JellyBean MR2.

Summary:
We noticed that on Android the lineHeight behaviour is different from iOS for built in fonts and custom fonts. The problem becomes visible when the lineHeight approaches the fontSize, showing a cut-off on the bottom of the TextView. This issue has been raised before in #10712. There is a mention of a PR with a fix in that issue, which has not been merged yet. This implementation is a less intrusive fix leaving the current lineHeight approach in place and fixing the discrepancy only.
This proposed change prioritises ascent over descent for reduction, making the lineHeight functionality behave identical to iOS.
There is no existing test covering the lineHeight property and its behaviour in the CustomLineHeightSpan. This PR contains new unit tests that covers the various scenario's for the lineHeight calculations.
The original behaviour, before the change can against these unit tests. The case that fails is `shouldReduceAscentThird`, which can be made to succeed on the old code by changing the asserts to:
```
assertThat(fm.top).isEqualTo(-5);
assertThat(fm.ascent).isEqualTo(-5);
assertThat(fm.descent).isEqualTo(-4);
assertThat(fm.bottom).isEqualTo(-4);
```
The unit test succeeds for the current implementation, which has the values for ascent and descent inverted.

it is useful for things like password and code entry fields. It can also be more

(like Gboard).
Note `secureTextEntry` also affects `TYPE_TEXT_VARIATION_*` flags internally, so there
may be some undefined behavior when combining `secureTextEntry` with
`keyboardType="visible-password"`
Also, while here, improve the documentation on TextInput to explicitly enumerate
which keyboardType applies to Android vs. iOS (since this is the first android-specific)

Summary:
Motivation:
(SUDDENLY) There is a thing on Android called SpanWather, and their purpose is to notify "the watcher" about span-related changes in SpannableString. The idea is: some special kind of span can have some logic to prevent or tweak interleaving with some another kind of spans. To do so, it has to implement SpanWather interface.
So, EditText uses this to control internal spannable object (!) and SUDDENLY (#><) calls internal "layout" method as a reaction to adding new spans. So, when we are cloning SpannableString, we are (re)applying same span objects to a new spannable instance, and it causes notifying other spans in the string, and they notify EditText, and the EditText does relayout and... BOOM!
So, the solution is, easy, we should use SpannableStringBuilder instead of SpannableString because it does not notify SpanWather during cloning.
See:
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/text/SpannableStringBuilder.java#101
(the first argument is `false`).
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/text/SpannableStringBuilder.java#678
Compare with:
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/text/SpannableStringInternal.java#43
Why? I believe because SpannableStringBuilder objects are "unfinished" by design, and documentation said: "it is the caller's responsibility to restore invariants [among spans]". As we do an exact clone of the string, that's perfectly okay to assume that all invariants were already satisfied for original string.

Note that this should not affect facebook internally since they are not using OSS releases.
Points to consider:
- How strict should the version match be, right now I just match exact versions.
- Wasn't able to use haste for ReactNativeVersion because I was getting duplicate module provider caused by the template file in scripts/versiontemplates. I tried adding the scripts folder to modulePathIgnorePatterns in package.json but that didn't help.
- Redscreen vs. warning, I think warning is useless because if the app crashes you won't have time to see the warning.
- Should the check and native modules be __DEV__ only?

Summary:
As I was working on mimicking iOS animations for my ongoing work with `react-navigation`, one task I had was to match the "push from right" animation that is common in UINavigationController.
I was able to grab the exact animation values for this animation with some LLDB magic, and found that the screen is animated using a `CASpringAnimation` with the parameters:
- stiffness: 1000
- damping: 500
- mass: 3
After spending a considerable amount of time attempting to replicate the spring created with these values by CASpringAnimation by specifying values for tension and friction in the current `Animated.spring` implementation, I was unable to come up with mathematically equivalent values that could replicate the spring _exactly_.
After doing some research, I ended up disassembling the QuartzCore framework, reading the assembly, and determined that Apple's implementation of `CASpringAnimation` does not use an integrated, numerical animation model as we do in Animated.spring, but instead solved for the closed form of the equations that govern damped harmonic oscillation (the differential equations themselves are [here](https://en.wikipedia.org/wiki/Harmonic_oscillator#Damped_harmonic_oscillator), and a paper describing the math to arrive at the closed-form solution to the second-order ODE that describes the DHO is [here](http://planetmath.org/sites/default/files/texpdf/39745.pdf)).
Though we can get the currently implemented RK4 integration close by tweaking some values, it is, the current model is at it's core, an approximation. It seemed that if I wanted to implement the `CASpringAnimation` behavior _exactly_, I needed to implement the analytical model (as is implemented in `CASpringAnimation`) in `Animated`.
We add three new optional parameters to `Animated.spring` (to both the JS and native implementations):
- `stiffness`, a value describing the spring's stiffness coefficient
- `damping`, a value defining how the spring's motion should be damped due to the forces of friction (technically called the _viscous damping coefficient_).
- `mass`, a value describing the mass of the object attached to the end of the simulated spring
Just like if a developer were to specify `bounciness`/`speed` and `tension`/`friction` in the same config, specifying any of these new parameters while also specifying the aforementioned config values will cause an error to be thrown.
~Defaults for `Animated.spring` across all three implementations (JS/iOS/Android) stay the same, so this is intended to be *a non-breaking change*.~
~If `stiffness`, `damping`, or `mass` are provided in the config, we switch to animating the spring with the new damped harmonic oscillator model (`DHO` as described in the code).~
We replace the old RK4 integration implementation with our new analytic implementation. Tension/friction nicely correspond directly to stiffness/damping with the mass of the spring locked at 1. This is intended to be *a non-breaking change*, but there may be very slight differences in people's springs (maybe not even noticeable to the naked eye), given the fact that this implementation is more accurate.
The DHO animation algorithm will calculate the _position_ of the spring at time _t_ explicitly and in an analytical fashion, and use this calculation to update the animation's value. It will also analytically calculate the velocity at time _t_, so as to allow animated value tracking to continue to work as expected.
Also, docs have been updated to cover the new configuration options (and also I added docs for Animated configuration options that were missing, such as `restDisplacementThreshold`, etc).
Run tests. Run "Animated Gratuitous App" and "NativeAnimation" example in RNTester.

Summary:
Fixes https://github.com/facebook/react-native/issues/15863 on master. Behavior of `onSubmitEditing` is now consistent between iOS and Android. Tapping the submit button in a TextInput dispatches the event precisely when doing so does not make a newline (when blurOnSubmit is true or multiline is false).
1. Run this app on iOS and Android:
```
// flow
import React, { Component } from 'react';
import {
StyleSheet,
TextInput,
View
} from 'react-native';
type State = {
toggled: boolean
};
type Props = {
blurOnSubmit: boolean,
multiline: boolean
};
class ToggleColorInput extends Component<Props, State> {
state: State = {
toggled: false
};
props: Props;
toggle = () => {
this.setState({
toggled: !this.state.toggled
});
}
render() {
return (
<TextInput
blurOnSubmit={this.props.blurOnSubmit}
multiline={this.props.multiline}
onSubmitEditing={this.toggle}
style={[styles.textInput, {backgroundColor: this.state.toggled ? 'blue' : 'azure'}]}
underlineColorAndroid='transparent'
/>
)
}
}
export default class App extends Component<{}> {
render() {
return (
<View>
<ToggleColorInput blurOnSubmit={true} multiline={true} />
<ToggleColorInput blurOnSubmit={true} multiline={false} />
<ToggleColorInput blurOnSubmit={false} multiline={true} />
<ToggleColorInput blurOnSubmit={false} multiline={false} />
</View>
);
}
}
const styles = StyleSheet.create({
textInput: {
height: 75,
borderWidth: 1,
borderColor: 'black'
}
});
```
2. You see four TextInputs, with each combination of the `blurOnSubmit` and `multiline` properties. For each TextInput, type some text and tap the submit button.
3. The TextInputs in this test will toggle background color when they emit an `onSubmitEditing` event. Verify the following behavior on each platform:
* blurOnSubmit && isMultiline => Submit event emitted, blurred, no newline inserted
* blurOnSubmit && !isMultiline => Submit event emitted, blurred
* !blurOnSubmit && isMultiline => Submit event emitted, newline inserted
* !blurOnSubmit && !isMultiline => Submit event emitted

Summary:
When we convert nested <Text> components to Spannable object we must enforce the order of spans somehow,
otherwise we will have Spannable object with unpredictable order of spans, which will produce unpredictalbe text layout.
We can do it only using `Spannable.SPAN_PRIORITY` feature because Spannable objects do not maintain the order of spans internally.
We also have to fix this to implement autoexpandable <TextInput>.
