This new version of metro replaces the `getProjectRoots()` config param by `getProjectRoot()` (which is used as the main folder for calculating relative paths of files, etc) and `getWatchFolders()` (which is used to know which files/folder to crawl when starting metro).

Summary:
Upgrade Babel from beta.40 to beta.47
There are two important breaking changes here.
- If you want an AST from the Babel `transform` functions you must pass on `ast:true` in the options.
- The `sourceType` is now the only source of truth on whether to parse with the Script or Module goal. It defaults to `script` and can also be `module` or `unambiguous`. In the `unambiguous` case it will first try to parse with the Module goal and only if it crashes it will try again with the Script goal.
Beyond that there were some fixes and some smaller changes that may affect you. See the Babel changelogs for details (https://github.com/babel/babel/tags).
Also updated the way we generate the babel helpers file.

Summary:
Allows us to parse the `import()` syntax. For now it's not transformed, so it would crash at runtime (or at minification with UglifyJS). However I want to release this under a new major version, so this wouldn't be allowed in OSS right away.
Also we bump to version 3.0.0 before release. D5443966 possibly introduced breaking changes, so it needs a major bump.

Summary:
Adding a Babel plugin that will analyze the file looking for any potential candidate to use `regenerator-runtime`, and if so, will inject dynamically the module. The module is injected per file, so we avoid polluting the global environment. The plugin is also able to inject the `require` call beforehand, so that the inliner can pick them and inline them.
The Babel plugin is part of `react-native-babel-preset`, so as long as you are using this preset you are safe. If not, you should include the specific transformer into your list of plugins, as `react-native-babel-preset/transforms/transform-regenerator-runtime-insertion.js`.

Summary:
The `env` option has been broken in Babel for a while (https://github.com/babel/babel/issues/4539), and will be deprecated (https://github.com/babel/babel/issues/5276).
I am changing this code to the way Babel < 6.10 interpreted the `env` option. This should fix the `__source` JSX transform which was applied in DEV in the past, but stopped getting applied because of the Babel bug.
I also changed the `filename` passed by Babel to be relative (currently, to `fbsource` but open to other options). This way DEV builds are still reproducible.
This still needs some help from davidaurelio to make the root location more foolproof. I'd also appreciate zertosh taking a look in case there's a better way to "anchor" the relative path. All I need is to for `react-third-party/react-devtools/react-devtools` and `babelTransformer.js` to agree on what the relative path base is.

Putting this up as request for comments.
The PR adds [transform-react-jsx-source](https://github.com/babel/babel/tree/master/packages/babel-plugin-transform-react-jsx-source) to the list of plugins that come by default with the `react-native` preset. It will enable the use of a bunch of really cool tooling around JSX, however those are generally useful only in development mode. Is changing `react-native` preset the right thing to do in this case? Is there a way to enable this transform only in DEV? Should I add this somewhere else?

Summary:PR does as it says -- updates Babel dependencies to latest versions.
In general, this changes nothing for 99.9% of users (everyone that isn't FB). If they were to `npm install react-native` right now, they would get all of these dependencies anyway.
However, this does revert a previous change where we were using "~" instead of "^" in front of the Babel deps in order to attempt to lock them to minor dependencies. However, due to the fact that each Babel package uses "^", and there are so many interdependencies, this actually would cause an issue where multiple versions of babel-core, et. al. to be installed.
*Edit* - In addition, we add React to `devDependencies` so that it behaves properly in testing, now that it's a peer dependency.

Summary:This imports `react-transform-hmr/lib/index.js` with a relative path from every module, to make sure we don’t rely on the current (broken) behaviour.
It works now, because:
- the dependency is added by a transform
- we extract dependencies before transforming
- we include `react-transform-hmr/lib/index.js` manually
- packager incorrectly names modules by the name of their package (i.e. packages with multiple versions overwrite each other)
This blocks transforming before extracting dependencies, switching to numeric module IDs, and unbundling/random access bundles.

Summary:
Turns out, even after discussion that was had in https://github.com/facebook/react-native/pull/5294#issuecomment-174397103, we really do need this transform.
I've just included it in the preset...let me know if you all would rather publish to npm.
The actual reason why this is necessary is because in the latest sync from FB, fbjs was updated to use the `Symbol.iterator` express in it's isEmpty function: 064a484e18
We use this in RN in the ListView...and this change (once #5084 is merged) will cause ListView to break on older JSC context's.
This resolves that, and is probably something we should have had all along.

Summary:
Rather than specifying Babel plugins in the `.babelrc` packaged with react-native, leverage a Babel preset to define the plugins (https://github.com/exponentjs/babel-preset-react-native).
This allows for a much better user experience for those who want (or need) to override options in their project's `.babelrc`.
Prior to this PR, if a user wanted to use a custom babel-plugin (or a custom set of babel plugins), they'd have either 1) manually override the `.babelrc` in the react-packager directory (or fork RN), or 2) specify a custom transformer to use when running the packager that loaded their own `.babelrc`. Note - the custom transformer was necessary because without it, RN's `.babelrc` options would supersede the options defined in the project's `.babelrc`...potentially causing issues with plugin ordering.
This PR makes the transformer check for the existence of a project-level `.babelrc`, and if it it's there, it _doesn't_ use the react-native `.babelrc`. This prevents any oddities with Babel plug
