Summary:
I noticed I didn't get type defs anymore for react-native. Looks like it is broken since we removed the .flow file in 3e153b2a5b. To fix it we can now enable flow in react-native-implementation since it now supports properties.
**Test plan**
Tested that I get type hints when using imports from react-native in a project.

Summary:
When using the following component, `this.props.children` is not a flat array.
``` js
class Example extends Component {
// ...
render() {
const values = ['1', '2'];
return (
<Picker
value={this.state.value}
onValueChange={this.onValueChange.bind(this)}
>
<Picker.Item
label="n/a"
value={null}
/>
{values.map(value => {
return (
<Picker.Item
label={value}
value={value}
/>
);
})}
</Picker>
);
}
}
```
The resulting `this.props.children` is:
``` js
[
(child),
[
(child),
(child),
],
];
```
Therefor you can't use `this.props.children[2]` to get the last item.

Summary:
Fixes https://github.com/facebook/react-native/issues/9216.
As nickzuber describes in #9216, conditional `Picker.Item` elements will lead to exceptions downstream when the `Picker` attempts to construct the collection of items.
[In the picker source](a2fb703bbb/Libraries/Components/Picker/PickerIOS.ios.js (L48-L53)) we can see that `child.props` is accessed when `child` has the potential to be an invalid `React` element.
```js
ReactChildren.forEach(props.children, function (child, index) {
if (child.props.value === props.selectedValue) {
selectedIndex = index;
}
items.push({value: child.props.value, label: child.props.label});
});
```
This change ensures the incoming element is valid
```diff
ReactChildren.forEach(props.children, function (child, index) {
+ if (!React.isValidElement(child)) {
+ return;
+ }
if (child.props.value === props.selectedValue) {
selectedIndex = index;
}
items.

Hi!
I found problem with accessibilityLabel on PickerAndroid.
There's no value in content-desc attribute while accessibilityLabel is correct.
I found that accessibilityLabel is not propagated into native components via
native props.
This PR brings accessibilityLabel for PickerAndroid.
Without this solution my appium tests fails, for example:
My code:
```jsx
<Picker
style={this.props.style}
selectedValue={this.props.value}
onValueChange={this.onChange}
disabled={this.props.disabled}
accessibilityLabel="select_wineType">
// Chilren
</Picker>
```
```sh
✖ Error: element (~select_wineType) still not visible after 5000ms
```
Because xml of this view is (look into content-desc of Spinner):
```xml
<android.widget.Spinner index="0" text="" class="android.widget.Spinner" package="com.hello_github" content-desc="" checkable="false" checked="false" clickable="true" enabled="true" focusable="true" focused="false" scrollable="true" long-clickable="false" password=

Summary: This removes `node_modules/react` from the list of directories that are used for haste module resolutions. Modules required from React are now imported with `require('react/lib/…')`.

Summary: Creating a view instance just to get the default view size is quite expensive, and affects startup time for the bridge as it must be done on the main thread. I've removed these cases and simply hard-coded the sizes in the JS file. This will need to be updated if the view sizes ever change, but in practice that's very unlikely.

Summary:According to the [docs](http://facebook.github.io/react-native/releases/0.20/docs/picker.html#onvaluechange), `Picker`'s `onValueChange` should be called with `itemValue` and `itemPosition` but currently only `itemValue` is passed. This PR fixes that.
The position is passed as the 2nd parameter to not introduce any breaking change, and also to respect the current documentation.
The documentation doesn't need to be changed as it will be correct with this PR, but maybe it needs to be updated until this is merged?

Summary:
The basic API is consistent with iOS; there are several platform-specific props.
Also fixed the flickering when a value is selected.
