* Fix button with react component doesn't get unmounted

* Test e2e only on iOS

Break all the PRs :(

iOS and Android code base used different naming conventions - this commit aims to unify naming conventions. I probably missed a few properties here and there so this will be an ongoing effort.

There is no need to call `setDefaultOptions` on the `childViewController` while iterating the `childViewControllers` as those will be passed recursively as `rootViewController` anyway and thus calling `setDefaultOptions` in the nested recursive call.

When setRoot is called with `waitForRender=true`, check if the root view is destroyed before displaying it.

* Don't cache values for constants() call

The reason we can not cache the values is because the implementation differs per OS. Android returns static values while iOS will actually crawl the layout and return it's heights. The caching mechanism here meant that iOS would only return the heights of the layout it calculated the first time.

* Update docs regarding inconsistencies in Constants

* updated Third Party libs

* add fab styling

* removed alignVertically

* Enabled option was wrongly consumed after it was merged. That meant that the next time SideMenu options were applied, the wrong enabled value was applied
* supportedInterfaceOrientations didn't take default orientation value into account
* mergeOptions didn't save the new options in the ViewControllers current options
* SideMenu always returned the centre ViewController as the current child and didn't take open SideMenu into account

Fixes #5444

This is already defined in UIViewController+LayoutProtocol and depending 
on the load order will actually prevent the default orders from being 
set

Fixed Android's native setStackRoot animation and added animation support for Android's setStackRoot.

The backButton options are always applied. Even when one of its values has changed in mergeOptions.
This commit adds a function to apply the backButton, and should probably replace the existing rnn_setBackButtonIcon - as that function does more than just set the icon, it sets all options.

Merging TopBar title, buttons and status bar options is broken on iOS in 3.1.1.
Parent options aren't resolved properly and default options aren't regarded when they should be.

Should fix a lot of the warnings when doing a clean yarn install

* fix #4625

* fixed renamed property

When defaultOptions are set after setRoot has been called presenters need to receive the default options as well,
otherwise the outdated default options are regarded.
Fixes #5395

Hermes doesn't support Proxy ¯\_(ツ)_/¯

This commit adds initial support for passing null as a valid value for color properties.
When a color property is applied, if it wasn't specified then the default color is applied. Now, when null is passed, no color will be applied
leaving the last color applied as is.

This is useful when showing an Overlay and you'd like to keep the current StatusBar color unaffected. Another usecase would be when you'd like to avoid coloring an icon in BottomTabs.

Current numbering causes the line 
```In Xcode, you will need to edit this file: AppDelegate.m. This function is the main entry point for your app:```
to appear as instruction 1, not 3.

Originally PR'd in #5338 but since the diff was too big I'm committing it here.

# Changes
* Support RN 0.60
* Migrate to AndroidX
* Improve draw behind StatusBar (Preparation for #4258)
* Don't push BottomTabs when keyboard is displayed (Fixes #4005, #3424)
    - It won't be needed to toggle the BottomTabs when Keyboard is visible
* BottomTab badge and dot indicator are not animated by default on Android (parity with iOS)

# Updating from v2
v3 is currently in alpha. To update simply npm install `3.0.0-alpha.11` - `npm install --save react-native-navigation@3.0.0-alpha.11`.
Breaking changes are outlined below.

## Layout system changes on **Android**
* Parent layouts (BottomsTabs, Stack, SideMenu) are always laid out behind the StatusBar.
* Components (`component` and `externalComponent`) are measured and offset according to the StatusBar.

In this release, We're changing the layout system in order to provide better support for immersive and full screen apps. In this release we've improved support for drawing behind the StatusBar,  next we'll address drawing behind the NavigationBar. 

Use the `drawBehind` and `translucent` options to control the StatusBar
```js
statusBar: {
  drawBehind: true,  // will draw a screen behind the StatusBar
  translucent: true // Usually you'll want to have drawBehind: true when this is true
}
```

While this isn't a breaking API change - there are a few breaking side effects.

### How will my app be effected
1. When the keyboard is opened, BottomTabs will now be drawn behind the keyboard and won't shift upwards. This is in parity with the current behaviour in iOS. For the most part, this isn't a breaking change. Toggling BottomTabs when TextInput's focus changes won't be needed anymore.

2. While parent controllers are drawn behind the StatusBar, their background isn't.
This means that when transitioning from a destinations drawn under the StatusBar to a destination drawn behind it, the application's default background color will be visible behind the StatusBar.
If you application's theme is dark, you might want to change the `windowBackground` property to mitigate this:

Add the following to your application's `style.xml`
```xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowBackground">@color/backgroundColor</item>
    </style>

    <!--This is your application's default background color.
    It will be visible when the app is first opened (while the splash layout is visible)
    and when transitioning between a destination a screen drawn under the StatusBar to
    a destination drawn behind it-->
    <item name="backgroundColor" type="color">#f00</item>
</resources>
```

## AndroidX migration
We've migrated RNN to AndroidX, please follow migration instructions in the react-native repo.

## Removed SyncUiImplementation
[SyncUiImplementation](https://github.com/wix/react-native-navigation/blob/master/lib/android/app/src/reactNative57WixFork/java/com/reactnativenavigation/react/SyncUiImplementation.java) was used to overcome a bug in RN's UiImplementation. This workaround was added to RN's `UiImplementation` in RN 0.60 (thanks @SudoPlz) and can be removed from RNN.

If you're using `SyncUiImplementation` your app will fail to compile after upgrading to v3. Simply remove the following code from your `MainApplication.java`
```diff
- import com.facebook.react.uimanager.UIImplementationProvider;
- import com.reactnativenavigation.react.SyncUiImplementation;


- @Override
- protected UIImplementationProvider getUIImplementationProvider() {
-     return new SyncUiImplementation.Provider();
- }
```

## BottomTab badge and dot indicator are not animated by default on Android (parity with iOS)
Showing and hiding badge and dot indicator are now not animated by default. Badge animation is now controlled with the `bottomTab.animateBadge` property and dot indicator with `bottomTab.dotIndicator.animate` property.

#### The following option will show a badge with animation
```js
bottomTab: {
  badge: 'new,
  animateBadge: true
}
```

#### The following option will show a dot indicator with animation
```js
bottomTab: {
  dotIndicator: {
    visible: true,
    animate: true
  }
}
```

closes #5228

Apply layout direction directly on views

This commit changes how RNN handles layout direction and adds support for LOCALE layout direction on Android.
Until now RNN delegated handling layout direction to RN's I18nUtil. This usually is enough but under certain circumstances
layout direction has to be applied directly on relevant views by RNN - usually when there are conflicts with another dependency
which handles RTL.

* Fixes unnecessary rendering of the last viewController in setStackRoot, Closes #5355

* Add setStackRoot unit tests

* Properly check setStackRoot animation and waitForRender of each child

* Read waitForRender from the last child of the new stackRoot

* Fixed indentation

* Use setStackRoot.waitForRender instead of push.waitForRender

* Fixed merge issues caused by the text editor

* removed eof newline

* Added a missing semicolon

* Variable toVC renamed to newVC for consistency

* Fixed indentation problems

When setting BottomTabs root, if one of the children was a stack with multiple children
and the top child in the stack had `drawBehind: true` while the bottom child had `drawBehind: false`,
sometimes the tabs' bottomMargin would be wrong since it was applied in onPreDraw.

Like all other options, buttons are applied when a screen becomes visible. This means that in a BottomTabs layout,
options are applied when a tab is selected. Since tab change happens involves only changing view visibility, and button creation take a bit long,
the buttons appear to flicker some times.
