There is a bug in the WebView that causes a spurious call to onReceivedError
whenever you download a file.

This commit is a workaround for that bug. The idea here is to try and detect
these spurious errors and drop them before they cause problems.

This commit should be reverted once those chromium bugs are fixed.

* Ensure each mounted WebView binds their personal onMessage handler

* Changed unique ref generation to uuid

Uses `uuid` npm package.
Dashes are removed from the ref for sanity.

This reverts commit acf1ad7560.

Hello, in order to use react-native-webview > 6.0.2 please make your android/gradle.properties contains:
```
android.useAndroidX=true
android.enableJetifier=true
```
This enables AndroidX libraries which are the new standard.

getJSEventName() needs a ScrollEventType parameter

* Add `onScroll` callback for iOS & Android

This code was mostly extracted from https://github.com/react-native-community/react-native-webview/pull/202

I tried and tried to make it work with `Animated.event`'s `useNativeDriver`, but I was unsuccessful 😢 that'll have to be done later once I understand better how Animated's native stuff is hooked up.

* fix crash for missing onScroll

* Extract WebChromeClient from an anonymous class

* Support fullscreen videos on Android

Forces landscape mode while playing.

* Use sticky immersive mode for fullscreen videos

No longer forces landscape mode as that is a problem for portrait videos - allow
the user to rotate as necessary.

Only supports KitKat or greater, and falls back to leaving the status and navigation
bars visible for lower than KitKat. This is the easiest way to prevent issues with
resizing the video during playback.

Also implement a lifecyle event listener which means if a user backgrounds the app
or locks the screen with the video fullscreen, the UI visibility is re-applied.

* Add allowsFullscreenVideo prop to control whether videos can be fullscreen on Android

Luckily, we're able to change the WebChromeClient on demand in response to prop changes
without seeming to do any harm. If you switch to disallow fullscreen, it will attempt
to close the currently fullscreened video (if there is one) so users aren't stuck.

I did notice a bug that if you go from fullscreen allowed, to fullscreen disallowed,
the fullscreen button will remain on the video. Tapping the button will have no effect.

When setting a custom font size in the Android system, an undesirable scale of the site interface in WebView occurs.

I researched that when setting the standard textZoom (100) parameter size, this undesirable effect disappears.

This can be very useful if you need to avoid the scale of content in WebView when changing the size of system fonts, or change textZoom property directly.

Example:

`
<WebView
  textZoom={100}
/>
`

Added an extremely simple `.editorconfig` I inferred from the main part of the project, then reformatted the codebase according to it. 🙂

`onShouldStartLoadWithRequest` event had only `url` in payload on android.
I've fixed it according to js event definition.

- One can verify that this for jpg images loaded on the webview (eg: https://www.ecda.gov.sg/growatbeanstalk/PublishingImages/READ%20Publications%20and%20Research/Parent%20Infographic%20Series/Infographic%204.jpg)
- This is a replication of the pull request that was originally made in the react-native repo (https://github.com/facebook/react-native/pull/17195), but was not merged in due to no reviews.

BREAKING CHANGE: Communication from webview to react-native has been completely rewritten. React-native-webview will not use or override window.postMessage anymore. Reasons behind these changes can be found throughout so many issues that it made sense to go that way.

Instead of using window.postMessage(data, *), please now use window.ReactNativeWebView.postMessage(data).

Side note: if you wish to keep compatibility with the old version when you upgrade, you can use the injectedJavascript prop to do that:

const injectedJavascript = `(function() {
  window.postMessage = function(data) {
    window.ReactNativeWebView.postMessage(data);
  };
})()`;

Huge thanks to @jordansexton and @KoenLav!

Added a new cacheEnabled prop to toggle Android & iOS webview caching behavior.

BREAKING CHANGE:  This change makes caching enabled by default when previously there was no caching behavior which may cause unexpected behaviour changes in your existing implementations.

Fixes #266. 
Now downloading works on Motorola Moto One with Android 9.

* add test code for disable hardware acceleration

* add interface to disable android hardware acceleration

* Update index.d.ts

fixes #240 #224

* [android] replace deprecated `WebView.PictureListener` onSizeChanged implementation

* [android] use pre-provided w/h values

Addresses #80.

Caveat: I am not an Android developer. This code comes from a fork of the original RN WebView that we have been using in production for some time, so all credit goes to @Oblongmana: https://github.com/Oblongmana/react-native-webview-file-upload-android.

Setting up a DownloadManager for the WebView is pretty straightforward, as is adding any known cookies to the request. Most of the complication comes from the requirement after SDK 23 to ask the user for the WRITE_EXTERNAL_STORAGE permission. Unfortunately there is no mechanism to suspend the download request until permission is resolved so this code stores off the request and sets up a listener that enqueues the download once permissions are resolved so the user experience is really nice.

I didn't see anything in the way of tests or documentation that needs to be added for this change, so let me know if I missed anything. Thanks!

This PR adds support for `onShouldStartLoadWithRequest` on android.

The initial PR was #59

The issue for this PR is: #106

Fixes #33 

I could really use some help from an Android developer on this one, because I just "made it work", don't know how to "make it work good".

Some things that should be reviewed:

- [ ] validate Android 5.0 devices (my emulator work, but outputs some weird sounds; a Galaxy 4 I tested on crashes)
- [ ] validate Android 5.1 devices (emulator works, couldn't find a real device)
- [ ] how to handle File Extensions? (https://www.w3schools.com/tags/att_input_accept.asp)

I'm sure that there's more refactoring to be done, so any help and advice would be appreciated.
