Summary:
This is a very hacky solution to make reloads from packager faster for simple file changes.
Simple means that no dependencies have changed, otherwise packager will abort the attempt to update and fall back to the usual rebuilding method.
In principle, this change avoids re-walking and analyzing the whole dependency tree, and just updates modules in existing bundles.

Summary:
We have a weak build machine for React Native app: a poor Mac Book Air with HDD, which is very slow.
So, fs operations sometimes fail because of timeout.
We likely don't care about build time, but it's pretty annoying to restart builds sometimes.
In this PR I make timeout injectable via environment variable.
__USAGE__:
export this variable into environment. It's measured in miliseconds.
Example, for 1 minute timeout:
`export REACT_NATIVE_FSOP_TIMEOUT=60000`
If you don't specify it, it will remain default value: `15000`
This should not break anything, but repair slow builds.

Summary:
This PR solves a problem when video assets are used from third-party React Native components (e.g. [react-native-video](https://github.com/brentvatne/react-native-video). The video will not work while the assets are served from the react native packager because the used video component (iOS) relies on HTTP range requests.
I added a small fix that allows ranged requests (e.g. mp4) to be served in ranges.
To test this:
1. make new react native project
1. add [react-native-video](https://github.com/brentvatne/react-native-video) to xcode project
1. add video component to your project
```
import Video from 'react-native-video';
var resolveAssetSource = require('react-native/Libraries/Image/resolveAssetSource');
/* ... /*
render() {
let source = resolveAssetSource(require('./someVideoFile.mp4')) || {};
return <Video /*....*/ source={source} />;
}
```
That should not work (if video is smaller than a few megabytes, open app a few times). Then add my fix, that should do the trick.

This will allow consumers to supply their own transformer to all `react-native` cli commands by simply implementing `rn-cli.config.js` and overriding `getTransformModulePath()`. That way they don't have to fork various parts of the iOS and Android build system that React Native already provides just to add a `--transformer` command line argument.
**Test plan:** Applied this patch to the React Native version in my app, implemented `getTransformModulePath()` in my `rn-cli.config.js`, and verified that my custom transformer is invoked.

Summary:
When an asset is included in a module, and the directory for that asset can't be found in any of the roots, it is hard to debug that, because the error message contains neither the name of the requested file, the sub directory it is located in, nor the roots that have been searched for it. It becomes more difficult, because that exception is created asynchronously. It contains the calling promise code.
This diff makes the error message more useful by including the name of the file, the sub directory, and the roots.

Summary:
This separates the babel config of the local-cli and the packager from the one used by the transforms of the packager since it doesn't run in the same environment and the local-cli/packager doesn't require react specific transforms and runs in node 4 so we can also avoid some es2015 transforms that node already supports.
I had to move the code in cli.js so it can still run in node 0.12 that doesn't support `const` since it is no longer transformed.
**Test plan**
Run the local-cli on node 0.12 and there should be a message saying that it requires at least node 4.
Run the local-cli on node 4 and 5 and everything should work the same as before.
I was also hoping for some perf gains but there was nothing noticeable. I did benchmark the babel-register call and it stayed pretty much the same. As for runtime performance it can help if there are optimisations for es2015 features in node.

Summary:
The way we currently symbolicate JS stack traces in RN during development time
(e.g. inside the RedBox) is the following: we download the source map from RN,
parse it and use `source-map` find original file/line numbers. All happens
inside running JSC VM in a simulator.
The problem with this approach is that the source map size is pretty big and it
is very expensive to load/parse.
Before we load sourcemaps:
{F60869250}
After we load sourcemaps:
{F60869249}
In the past it wasn't a big problem, however the sourcemap file is only getting
larger and soon we will be loading it for yellow boxes too: https://github.com/facebook/react-native/pull/7459
Moving stack trace symbolication to server side will let us:
- save a bunch of memory on device
- improve performance (no need to JSON serialize/deserialize and transfer sourcemap via HTTP and bridge)
- remove ugly workaround with `RCTExceptionsManager.updateExceptionMessage`
- we will be able to symbolicate from native by simply sending HTTP request, which means symbolication
can be more robust (no need to depend on crashed JS to do symbolication) and we can pause JSC to
avoid getting too many redboxes that hide original error.
- reduce the bundle by ~65KB (the size of source-map parsing library we ship, see SourceMap module)

Summary:
This pull request is a prerequisite to enabling the react-native-windows platform extension.
In the Resolver component, we need to add 'windows' to the list of platforms that are allowed in the DependencyGraph. We also need to add 'react-native-windows' (the name of the Windows platform extension NPM module) to the `providesModuleNodeModules` option. This allows the node_module folder check in the DependencyGraphHelper from node-haste to be bypassed for *.windows.js files in the Windows NPM package.
For good measure, I also included a change to blacklist.js to ensure .windows.js files are ignored when the packager is parameterized on a platform.

This got broken recently. As a result of this, when a module throws while being required, either by regular load or hot reload, the module object is marked as `hasError`. Form that point all subsequent HMR updates will fail because it will think the module failed while executing the factory but the failure could have been on an old run of an old factory.
The fix is very simple: just reset `hasError` to false when accepting a module.
