Douglas 45185947ee Fix tvOS compile issues; enable TVEventHandler in Modal (fix #15389)
Summary:
**Motivation**

Fix an issue (#15389) where `TVEventHandler` would not work when a modal was visible.  The solution adds the gesture recognizers from the native `RCTTVRemoteHandler` to the native modal view (except for the menu button recognizer, which still needs special handling in modals).  This PR also fixes some breakages in compiling React Native for tvOS.

**Test plan**

Compilation fixes should enable tvOS compile test to pass in Travis CI.

The modal fix can be tested with the following component, modified from the original source in #15389 .

``` javascript
import React, { Component } from 'react';
import ReactNative from 'ReactNative';
import {
    Text,
    View,
    StyleSheet,
    TouchableHighlight,
    TVEventHandler,
    Modal,
} from 'react-native';

export default class Events extends Component {

    constructor(props) {
        super(props);

        this.state = {
            modalVisible: false,
        };
        this._tvEventHandler = new TVEventHandler();
    }

    _enableTVEventHandler() {
        this._tvEventHandler.enable(this, (cmp, evt) => {
            const myTag = ReactNative.findNodeHandle(cmp);
            console.log('Event.js TVEventHandler: ', evt.eventType);
            // if (evt.eventType !== 'blur' && evt.eventType !== 'focus') {
            //  console.log('Event.js TVEventHandler: ', evt.eventType);
            // }
        });
    }

    _disableTVEventHandler() {
        if (this._tvEventHandler) {
            this._tvEventHandler.disable();
            delete this._tvEventHandler;
        }
    }

    componentDidMount() {
        this._enableTVEventHandler();
    }

    componentWillUnmount() {
        this._disableTVEventHandler();
    }

    _renderRow() {
        return (
            <View style={styles.row}>
                {
                    Array.from({ length: 7 }).map((_, index) => {
                        return (
                            <TouchableHighlight
                                key={index}
                                onPress={() => { this.setState({ modalVisible: !this.state.modalVisible }); }}
                            >
                                <View style={styles.item}>
                                    <Text style={styles.itemText}>{ index }</Text>
                                </View>
                            </TouchableHighlight>
                        );
                    })
                }
            </View>
        );
    }

    onTVEvent(cmp, evt) {
      console.log('Modal.js TVEventHandler: ', evt.eventType);
    }

    hideModal() {
      this.setState({
        modalVisible: false
      });
    }

    render() {
        return (
            <View style={styles.container}>
                <Modal visible={this.state.modalVisible}
                       onRequestClose={() => this.hideModal()}>
                    <View style={styles.modal}>
                        { this._renderRow() }
                        { this._renderRow() }
                    </View>
                </Modal>
                { this._renderRow() }
                { this._renderRow() }
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        backgroundColor: 'darkslategrey',
    },
    row: {
        flexDirection: 'row',
        padding: 30,
    },
    item: {
        width: 200,
        height: 100,
        borderColor: 'cyan',
        borderWidth: 2,
        margin: 30,
        alignItems: 'center',
        justifyContent: 'center',
    },
    itemText: {
        fontSize: 40,
        color: 'cyan',
    },
    modal: {
        flex: 1,
        backgroundColor: 'steelblue',
    },
});
```
**Release Notes**

After this change, the `onRequestClose` property will be required for a `Modal` in Apple TV.

RNTester

The RNTester showcases React Native views and modules.

Running this app

Before running the app, make sure you ran:

git clone https://github.com/facebook/react-native.git
cd react-native
npm install

Running on iOS

Mac OS and Xcode are required.

  • Open RNTester/RNTester.xcodeproj in Xcode
  • Hit the Run button

See Running on device if you want to use a physical device.

Running on Android

You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.

Start an Android emulator (Genymotion is recommended).

cd react-native
./gradlew :RNTester:android:app:installDebug
./scripts/packager.sh

Note: Building for the first time can take a while.

Open the RNTester app in your emulator.

See Running on Device in case you want to use a physical device.

Running with Buck

Follow the same setup as running with gradle.

Install Buck from here.

Run the following commands from the react-native folder:

./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch rntester
buck install -r rntester
./scripts/packager.sh

Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).

Built from source

Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.

This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
