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:
Currently the `react-native bundle` has no option to reset the file cache. For example changing the .babelrc has no effect on the bundling process. `react-native start` has it already implemented, so this is just a small addition.
**Test plan (required)**
the issue:
- `react-native init` a new project
- run `react-native bundle` (should work as expected)
- create `.babelrc` with empty object ```{}```
- rerun `react-native bundle`
- should fail now with `Unexptected token` (no babel plugins configured)
- if not failing, your cache already hit (clear $TMPDIR to get the error)
- delete .babelrc and rerun `bundle`
- still failing, but it should went back to normal
- delete your $TMPDIR contents
- works again
The option `--reset-cache` should fix that

Tested that the packager is launched in a completely independent process.

Summary:
IIRC we made `wrong-react-native` to warn people in case they installed `react-native` globally (instead of `react-native-cli` what the guide suggests). To do that we added `bin` entry to React Native's `package.json` that points to `local-cli/wrong-react-native.js`
However, this means that if we have a project that uses `react-native` package and has call to `react-native` CLI inside its package.json, npm will execute *local* override (which just prints a confusing in this context error message).
In fact, the template we generate with `react-native init` has `react-native start` as `start` script, which makes it useless. Let's fix it by making `wrong-react-native` script smarter – it can detect that it has been executed from local `node_modules` and run the actual CLI.

Indeed, this directory doesn't exist on my computer.

Summary:This PR is to solve app build issue when node_modules is a symlink by providing an environmental variable to override the current *smart* guessing of app root path.
I met this issue when I tried to setup a shared incremental node_modules directory to speed our react-native app build speed in CI. But the build crashed in step 'bundleReleaseJsAndAssets' with error messages like:
> :app:bundleReleaseJsAndAssets
> bundle: Created ReactPackager
> uncaught error Error: NotFoundError: Cannot find entry file index.android.js in any of the roots:["/home/jenkins/shared_data"]
The build is fixed by applying this patch and adding 'export react_native_app_root=${WORKSPACE}' before './gradlew assembleRelease' in build script.
**Test plan**
1. react-native init demo # init a demo app from scratch
2. cd demo/android && ./gradlew assembleRelease # build works fine
3. mkdir ~/shared_data && mv ../node_modules ~/shared_data && cd .. && ln -s ~/shared_data/node_modules . # create symlink for node_modules in shared d

Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.

Summary:This adds support for source maps that can be used for “random access modules” / “unbundles”
- source maps contain an extra custom field: `x_facebook_offsets`
- this field maps module IDs to line offsets
- the source map is built as if all files were concatenated
Decoding/symbolication works as follows:
- when decoding a stack trace, and a stack frame comes from a filename that contains only numbers and ends with `.js`, look up the additionally needed line offset in the offset map and add it to the original line of the stack frame.
- consume the source map as usual

Summary:We use a few different modules to output logs to stdout when building a bundle with the packager:
- ##js/react-native-github/packager/react-packager/src/Activity/index.js##
- ##js/react-native-github/local-cli/util/log.js##
- ##https://www.npmjs.com/package/progress##
This diff also adds a ##silent## option to the packager ##Server##, which, when ##true##, will not create a ##progress## instance for the transformer.

Summary:Use the new numeric module IDs for indexed-file random access bundles, rather than string-based module names
This still uses those IDs as strings in the table, to make this bundle format work again.

Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.
Original Description:
Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

Summary:Name resolution of inversed dependencies used to happen in node-haste, but that makes it difficult switiching to numeric module IDs.
This moves the name resolution to the HMR server in order to be able to change the logic more easily.
node-haste 2.9.0 provides a `Map` of modules to `Set`s that contain the modules that depend on the key.

Summary:This rev adds support for production sourcemaps on RAM.
When we inject a module into JSC we use the original `sourceURL` and specify the `startingLineNumber` of the module relative to a "regular" bundle. By doing so, when an error is thrown, JSC will include the provided `sourceURL` as the filename and will use the indicated `startingLineNumber` to figure out on which line the error actually occurred.
To make things a bit simpler and avoid having to deal with columns, we tweak the generated bundle so that each module starts on a new line. Since we cannot assure that each module's code will be on a single line as the minifier might break it on multiple (UglifyJS does so due to a bug on old versions of Chrome), we include on the index the line number that should be used when invoking `JSEvaluateScript`. Since the module length was not being used we replaced the placeholder we have there for the line number.
