Summary:
* The dev support code moved into a `DevSupport` subspec, meaning that only if the subspec is specified in the user’s Podfile will the packager client, dev menu, etc be included. This is mainly done through checks for header availability.
It also improves the weird situation where you had to specify the `RCTWebSocket` subspec if you wanted to be able to use the packager client during development.
* I removed hardcoding the release version in the podspec on release, because the podspec still relies on `package.json` when evaluating, so there’s no real point in not also getting the version number from there. This should remove any requirement to perform maintenance of the OSS release script regarding the podspec.

Summary:
This decouples non-UI logic from RCTDevMenu into a new module RCTDevSettings.
**Motivation**: This allows developers to change dev settings without depending on the built-in dev menu, e.g. if they want to introduce their own UI, or have other devtools logic that doesn't depend on an action sheet.
It also introduces the RCTDevSettingsDataSource protocol for storing dev tools preferences. This could allow a developer to implement alternative behaviors, e.g. loading the settings from some other config, changing settings based on the user, deciding not to persist some settings, or something else.
The included data source implementation, RCTDevSettingsUserDefaultsDataSource, uses NSUserDefaults and is backwards compatible with the older implementation, so **no workflows or dependent code will break, and old saved settings will persist.**
The RCTDevMenu interface has not changed and is therefore also backwards-compatible, though
some methods are now deprecated.
In order to ensure that RCTDevSettings

Summary:
Since we are reading from a file, we should make sure this struct is packed, just in case we change it down the line and the compiler decides it might want to introduce padding, we're now protected against that.
There was also a discussion about the fact that people might use `ptr += sizeof(BundleHeader)` as an idiom in their code, which would currently be incorrect, if padding was introduced at the end of the file. Actually, it remains incorrect to do that now, because a RAM bundle header is a different size to a BC Bundle header. If people are properly testing their code, they should spot this pretty quickly, because it will always be an incorrect thing to do with a RAM bundle, so this isn't as bad as previously thought: where the code only succeeds when the compiler deigns to not pad the struct at the end.
This diff also cleans up how headers are initialised. `BundleHeader` has a constructor that explicitly zero-initialises it so we can rely on the default initializer to do the right thing now.

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary:
**Motivation**
I'm working on a project that uses React Native and needs to add direct synchronous bindings to native stuff through the JavaScriptCore C API. This is because it's performance-sensitive and would benefit from the quickest JS->C path. It does this using cross-platform C++ code that works on both iOS and Android. Most of the infrastructure for getting access to the JSC context is already in React Native actually, just had to add a few more things.
(lexs you mentioned to tag you in this pull request)
**Test plan**
Modify the JavaScriptCore context through the `JSContextRef` returned (eg. add an object at global scope) and verify that it exists in JavaScript.

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:
The `initWithJSContextProvider:` API created a `RCTJSCExecutor` with a thread/context that already exists, but it did not solve the problem of loading an actual application script; the `executeApplicationScript:` API is also asynchronous.
Create a new merged API that allows you to pass in a pre-created thread/context pair and immediately receive an `RCTJSCExector` that has already executed a specified application script.
This also removes the `underlyingJSContext` API entirely, in favor of passing it back in a byref variable in the new API. This minimizes the surface area for API abuse.
