Mohammed 0150bc76eb Updating the documentation for getSize()
Summary:
Clearly state that the `getSize()` does not work for static image resources because it is assumed the developer knows their static image resource size (the reason I got from a comment on a github issue by a react native contributor).

This missing documentation cost me about 30 minutes to figure out why it didn't work for my static image resource and so I decided to update the documentation 💃

Janic Duplessis abc483a653 BREAKING - Remove LayoutAnimation experimental flag on Android
Summary:
I don't remember exactly where we talked about this but LayoutAnimation on Android is pretty stable now so there's no reason to keep it behind an experimental flag anymore. The only part that is not really stable is delete animations, so what I did is remove the default delete animation that we provide in presets.

**Test plan**
Tested that layout animations work properly without any config.

Adam Comella 454ab8fc23 BREAKING: iOS: Support withCredentials flag in XHRs
Summary:
Corresponding Android PR: #12276

Respect the withCredentials XMLHttpRequest flag for sending cookies with requests. This can reduce payload sizes where large cookies are set for domains.

This should fix #5347.

This is a breaking change because it alters the default behavior of XHR. Prior to this change, XHR would send cookies by default. After this change, by default, XHR does not send cookies which is consistent with the default behavior of XHR on web for cross-site requests. Developers can restore the previous behavior by passing `true` for XHR's `withCredentials` argument.

**Test plan (required)**

Verified in a test app that XHR works properly when specifying `withCredentials` as `true`, `false`, and `undefined`. Also, my team uses this change in our app.

Adam Comella 22b3faf1ad iOS: Expose fontScale to JavaScript
Summary:
A related Android PR is #11008.

Font scale was exposed through:
  - The `getContentSizeMultiplier` method
  - The `didUpdateContentSizeMultiplier` event

These are now deprecated. The reason is that there was already an API that exposed font scale. However, it was Android only. We now expose font scale through that API on iOS as well. Specifically:
  - Font scale is now available as `PixelRatio.getFontScale()`.
  - The `change` event on the `Dimensions` object now fires when font scale changes.

This change also adds support for `Dimensions.get('screen')` on iOS. Previously, only `Dimensions.get('window')` was available on iOS. The motivation is that, [according to this comment](https://github.com/facebook/react-native/pull/11008#issuecomment-275123609), we'd like to deprecate `window` dimensions in favor of `screen` dimensions in the future.

**Test plan (required)**

Verified that `PixelRatio.getFontScale()` and the `change` event work properly in a test app.

Adam Comella 4c7576e485 Android: Fix clipping of text which contains unicode emoticons on Android 4.4.2
Summary:
Fixes #11592

This bug was seen on a Galaxy S4 running Android 4.4.2. On this device, Android's `Layout.getDesiredWidth` method doesn't correctly measure text that contains unicode emoticons. It appears to think the emoticons take up 0 space.

Setting ANTI_ALIAS_FLAG in the TextPaint's constructor instead of setting it later with setFlags works around the Android bug.

Spencer Ahrens 7eded2d8ed preserve inline components in prop type doc gen
Summary:
Some of the operations, like `oneOf` and `arrayOf`, were doing joins on arrays of potential
tags, like `<span>` or `<a>`, which would stringify them to `[object Object]`.

This introduces a new `spanJoinMapper` which suppresses the trailing separator like `join` but wraps
elements in `<span>` rather than `concat`ing into a string.

At times, ReactPackage needs to get information from the ReactInstanceManager, e.g. to get the DevSupportManager for debugging purpose. This allows passing down the instance manager to create the native modules, in addition to just ReactApplicationContext. It is then up to the Package to use it or not.

To use this, you must make your package class extends ReactInstancePackage, instead of just implementing ReactPackage interface.

Eric Rozell dd5798b57b Workaround for P/Invoke AccessViolationException
Summary:
The issue is on ARM builds for Windows UWP. For the C# P/Invoke API wrapper, any native method that returns the YogaValue struct throws the AccessViolationException. The issue is not with structs in general, as returning the YogaSize / YGSize struct works fine. The issue seems to be limited to structs that have an enum member.

I tried a number of things to resolve the issue without changing the underlying native API for Windows. I read the ARM documentation and saw reference to variable enum sizes based on the number of enum members, so I tried to use a number of different UnmanagedType values in a [MarsalAs()] attribute on the enum member of the C# struct declaration.

What ultimately worked was to return a pointer to the location of the struct, and use the System.Runtime.InteropServices.PtrToStructure API to read the struct data from that pointer. I added a few new macros that will return the struct address on Windows only, other builds are not affected.

Note, I have not tested the impact of this ch

Vedad Sose f126540519 Fix linking manager library name in documentation
Summary:
I had an issue while using

```#import "RCTLinkingManager.h"```

![image](https://cloud.githubusercontent.com/assets/1089932/22933908/523cf910-f2cd-11e6-9c20-b3c298d5b7cc.png)

But when replaced with

```#import <React/RCTLinkingManager.h>```

the build succeeds.

Looks fine on the website:

Richard Evans 4471c32b08 CLI: Assign project root concat back to project roots.
Summary:
With the latest version of React Native I noted my setup with React Native Storybook stopped working because it stopped searching all the right project roots. I found that it had to do with the change here bce6ece5f6

**Test plan (required)**

Run the CLI with a project root other then the root directory and ensure that it displays both the specified project root and the actual root directory.

Janic Duplessis 7d06c35d1c Run install third party script as part of the xcode build
Summary:
Runs the `./ios-install-third-party.sh` script as part of the build process to avoid having to do it manually when building the cxx bridge with xcode. Also added the third-party dir to gitignore.

**Test plan**
Tested that just building works when the third-party dir is missing.

Summary:
