Summary:
Packager can take a long time to load and the progress is usually displayed in another window (Terminal). I'm adding support for showing a UI inside React Native app for packager's progress when loading a bundle.
This is how it will work:
1. React Native sends request to packager with `Accept: multipart/mixed` header.
2. Packager will detect that header to detect that client supports progress events and will reply with `Content-Type: multipart/mixed`.
3. While building the bundle it will emit chunks with small metadata (like `{progress: 0.3}`). In the end it will send the last chunk with the content of the bundle.
4. RN runtime will be receiving the events, for each progress event it will update the UI. The last chunk will be the actual bundle which will end the download process.
This workflow is totally backwards-compatible -- normally RN doesn't set the `Accept` header.

Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary:
If we use RCTLogError, we show a redbox with a native stacktrace before we can actually show the JS stacktrace (which is only done through dispatch_async). Instead use RCTLogWarn so its logged to console but not reported as a redbox.
Also fix call to RCTNSErrorFromJSErrorRef off the main thread RCTJSCExecutor.

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

At the moment, posting RCTReloadNotification in any circumstance causes all RCTBridge instances to reload. This change scopes the notification to the bridge for which it was intended.

Summary:
Include CSSLayout headers in the same way as other project headers, ie `#import <CSSLayout/CSSLayout.h>` becomes `#import "CSSLayout.h"`. CSSLayout is not a framework or system dependency, so shouldn't (AFAIK) be included with angle brackets. Doing so breaks framework builds, such as when RN is used as a pod in a swift project.
In combination with https://github.com/facebook/css-layout/pull/217 this fixes https://github.com/facebook/react-native/issues/9014 (specifically swift cocoapods projects). There is then no need for a separate CSSLayout pod subspec.
Tests run on the RN project in isolation (with changes inside `CSSLayout` itself also applied) and against a dummy swift project with RN included as a pod.
NB: This effectively reverts https://github.com/facebook/react-native/pull/9015 and may break non-swift cocoapods projects unless https://github.com/facebook/css-layout/pull/217 is merged and synced first.
Update: As discussed with alloy and emilsjolander, wrap these imports in a preprocess

First of all,please forgive my poor english. LOL
When I use Promises as callBack,
I followed the guide to make a (RCTPromiseRejectBlock),in this RCTPromiseRejectBlock,
from the guide I should add a (NSString)code a (NSString)message and an (NSError) to a RCTPromiseRejectBlock.
As what did guide said I just make a NSError with
```
NSError *error=[NSError errorWithDomain:@"native stroage error" code:402 userInfo:@{@"data":key}];
```
As you can see, I want to transfer some data in this callback.But I just found the (userInfo) of NSError didn't composed to a RCTPromiseRejectBlock.
So I check out the source code of RCTUtil ,I found this
```
// TODO: Can we just replace RCTMakeError with this function instead?
NSDictionary<NSString *, id> *RCTJSErrorFromCodeMessageAndNSError(NSString *code,
NSString *message,
NSError *__nullable error)
{
NSString *errorMessage;

Summary:
The overflow prop needs to be set on the shadow view so that it can make its way into the layout engine. In some situations, the value of the overflow prop affects the calculations of the layout engine.
**Test plan (required)**
Verified in a test app that the `overflow` prop makes its way into the layout engine. Also, my team's app is currently using this change.

Summary:
**Motivation:** We have a project that dynamically changes classes in runtime. This component is initialised within the React Native context. Therefor `RCTBatchedBridge` copies the classes before changes are made to them. While React Native is running, changes are made to the classes dynamically. When the project reloads the `RCTBatchedBridge`, it now has an invalid list of classes containing trash pointers. This causes the project to crash on https://github.com/facebook/react-native/blob/master/React/Base/RCTBatchedBridge.m#L288 with EXC_BAD_ACCESS in the DEBUG-mode.
**Solution:** Copy the class list on each reload to get the current state. Since this is only a DEBUG-feature the overhead of this should not be a major issue.

Summary:
When you call `-[RCTConvert UIFont:withFamily:...]` with a non-nil font object, we'll try to use the existing font object for system information. On iOS9+ which uses the San Francisco font, `[UIFont fontNamesForFamilyName:]` doesn't return anything useful, so we need to make sure that we detect this as a system font and use the appropriate methods. This issues is made worse by the fact that RCTTextView and friends recreate the font property for every attribute that is set (pretty horrible perf-wise).
