Merge "Fix WebView Metrics opt out Javadoc formatting" into nyc-dev

 * helps Google improve WebView. Data is collected on a per-app basis for each app which has

 * instantiated a WebView. An individual app can opt out of this feature by putting the following

 * tag in its manifest:

 * </p>

 * <pre>

 * <meta-data android:name="android.webkit.WebView.MetricsOptOut"

 *            android:value="true" />

 * <meta-data android:name="android.webkit.WebView.MetricsOptOut"

 *            android:value="true" />

 * </pre>

 * </p>

 * <p>

 * Data will only be uploaded for a given app if the user has consented AND the app has not opted

 * out.
