Summary:
Suppose that the user is scrolled to the bottom of a ScrollView. Next, the ScrollView's content is edited such that the height of the content changes and the current scroll position is larger than the new height of the content. Consequently, the user sees a blank ScrollView. As soon as the user interacts with the ScrollView, the ScrollView will jump to its max scroll position.
This change improves this scenario by ensuring that the user is never staring at a blank ScrollView when the ScrollView has content in it. It does this by moving the ScrollView to its max scroll position when the scroll position after an edit is larger than the max scroll position of the ScrollView.
Here are some pictures to illustrate how this PR improves the scenario described above:

Summary:
The logic in `ModuleGraph/Graph` allowed the callback to be invoked twice, if two invocations of `resolve` call back with errors asynchronously.
This fixes that problem by always calling `queue.kill()` on the asynchronous queue, and only invoke the main callback from the `drain` and `error` queue callbacks.

In one of my files I have:

When I run the tests it gives this error, which seems to be because StatusBarManager is undefined (https://github.com/facebook/react-native/blob/master/Libraries/Components/StatusBar/StatusBar.js#L20)

**Motivation**
On Exponent we load fonts dynamically and assign their native names by appending a session id, so that fonts from one Exponent "experience" do not clash with each other. So, before sending the `fontFamily` to native, we want to change it to the Exponent-scoped `fontFamily`.
Example:
```js
// Before rendering your app
StyleSheet.setStyleAttributePreprocessor('fontFamily', _processFontFamily);
function _processFontFamily(name) {
// Pass system fonts through
if (!name || Constants.systemFonts.indexOf(name) >= 0) {
return name;
}
if (!Font.isLoaded(name)) {
if (__DEV__) {
console.error(`${name} is not a system font and has not been loaded through Exponent.Font.loadAsync. If you intended to use a system font, make sure you typed the name correctly and that it is supported by the current operating system. If this is a custom font, be sure to load it with Exponent.Font.loadAsync`);

Summary:
ReactAndroid/build.gradle downloads a number of ad-hoc dependencies from the internet such as boost, JSC headers, and folly. Having the build depend on the internet is problematic. For example, if the site hosting the JSC headers was to go down, then CI builds would start failing.
This change introduces the environment variable REACT_NATIVE_DEPENDENCIES which refers to a path. Developers can pre-download all of the ad-hoc dependencies into that path and then the build process will grab the dependencies from that local path rather than trying to download them from the internet. This solution is in the spirit of the existing REACT_NATIVE_BOOST_PATH hook.

Summary: For having a global cache, we need cache keys that are the same from different machines, so we cannot include user/machine-specific information. In that regard, I suggest we consider the paths relatively to the install directory of the React Native instead of being absolute, so that they are more chances they stay stables between different installations, users, machines.

Summary:
This diff attempts to fix a number of iOS native animation bugs related to improper node invalidation and a race with view creation. The major issues were presented in #9120 as problems 3 and 3b, but I'll recap here:
The invalidation model we use is overly complicated and incomplete. The proper combination of `_needsUpdate` and `_hasUpdated` will result in nodes values being recomputed. However, we do not invalidate nodes in all the places we should, e.g. if we create a new view and attach it to an existing value node (see example in #9120). This diff chooses to remove the `_hasUpdated` flag, and simply relies on the `_needsUpdate` flag to mark a node as dirty.
We mark nodes as dirty when they are:
- created
- updated
- attached to new parents
- detached from old parents
- attached to a view
Calling `updateNodeIfNecessary` will, if necessary, compute all invalidated parent values before recomputing the node value. It will then apply the update, and mark the no

Summary:
The upgrading process based on Yeoman is a pain. For each file, Yeoman (or the brand new copyAndReplace solution a477aec) compares the newly generated content with the existing one and prompts the user if it differs, with very basic options: overwrite or skip.
I have digged into this problem and came with [rn-diff](https://github.com/ncuillery/rn-diff) (you may have read [this article](https://medium.com/ncuillery/easier-react-native-upgrades-with-rn-diff-5020b5c3de2d#.llvy2dym5)). This repository helps people to upgrade RN on their projects. An alternative upgrading process using `git apply` instead of Yeoman is described [here](https://github.com/ncuillery/rn-diff/blob/master/USAGE.md).
This PR is the integration of this process into the core. I got rid of the drawbacks mentioned in the link below in order to make it a clean, elegant, one-step operation.

Instead of exposing a `getTransformOptionsModulePath` function in configurations, we can simply expose a `getTransformOptions` *function*. The necessity of exposing a path comes from the olden days, where we had a server listening on a socket, and a client, talking to that server.
Since that architectural gem no longer exists, we can use functions directly, rather than passing paths to modules around.

Summary:
The `FrescoModule` supports providing a custom image pipeline configuration. This module is created by `MainReactPackage` but `MainReactPackage` doesn't expose any way to customize the Fresco configuration. This change adds a parameter to `MainReactPackage`'s constructor so that the `FrescoModule`'s configuration can be customized by the app. A couple of design choices were made in this change:
- `MainReactPackage`'s new constructor parameter is a `MainPackageConfig`. Introducing `MainPackageConfig` enables `MainReactPackage` to nicely support new optional configuration options in the future. Imagine the alternative of each optional configuration being a separate parameter to the `MainReactPackage` constructor.
- `FrescoModule` exposes its default configuration as a builder object through the `getDefaultConfigBuilder` method. This enables app's to start with `FrescoModule`'s default configuration and then modify it.
