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.

Fixing a bug detailed in Issue #7526 where Android app was crashing when using a binary number.
**Test plan:**
- Build & Run UIExplorer
- Build & Run UIExplorer with `const binaryNumber = 0b101010` inserted into UIExplorerApp.android.js
- Use `react-native init` to create a new blank project, then replace files in node_modules and insert `const binaryNumber = 0b101010` into index.android.js.

Summary:
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?

This patch updates the babel preset to use check-es2015-constants which should be more future-proof and will receive bug fixes.

Summary:Since #5422 react-native works with strict mode modules but the transform was not updated since Facebook has some non strict mode compatible internal modules. Now that #5214 has landed and it is easy to change the babel config I think we should enable it by default to make es2015 modules spec compliant.
Someone at Facebook will have to make the internal changes necessary to disable strict mode modules for their projects that use non strict mode compatible modules by including a .babelrc file with
``` json
{
"presets": [
"react-native"
],
"plugins": [
["transform-es2015-modules-commonjs", { "strict": false, "allowTopLevelThis": true }]
]
}
```
before merging this.
We might also want to mention this in the breaking change section for the next release.

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
