Setup global error handling infrastructure

[acostalima]

See global.ErrorUtils.setGlobalHandler.

Example:

import { ExceptionsManager } from 'react-native';

global.ErrorUtils.setGlobalHandler((e, isFatal) => {
  if (__DEV__) {
    // In DEV, pass the error to the standard ExceptionsManager
    // This way you'll still get nice RSODs in DEV
    ExceptionsManager.handleException(e, isFatal);
  } else {
    // Not in DEV. Send the exception 'e' to your logger of choice
    sendErrorToCrashReporter(e.message);
  }
});

I'm not sure whether React Native exports ExceptionsManager, but it can be found at https://github.com/facebook/react-native/blob/7d1d4dc0645a5dfecc53d05b16338f9c08cc0d0f/ReactAndroid/src/main/java/com/facebook/react/modules/core/ExceptionsManagerModule.java

NOTE: setGlobalHandler does not catch native iOS and Android exceptions. Without further action if, e.g., sendErrorToCrashReporter throws, the app will crash with no useful feedback to the user. In order to handle native exceptions gracefully with enhanced user experience, consider something like react-native-exception-handler, maybe fork it or develop our own custom solution.
