Summary: Makes it so that the default transformer loads babel-preset-react-native again if no project `.babelrc` is defined. This makes tests like `react-native/scripts/run-android-local-integration-tests.sh` work again.

Summary: Moves the `buildRegExps` function from `react-native` to `metro-babel-register`. This way, it is easier to reuse, and we can remove FB-specific logic from React Native.

Summary: Moves the implementation of Buck’s worker protocol into its own package and babelRegisterOnly for better reusability.

Summary: For specific cases, Metro will write the number of modules to the bundle. The require implementation can take advantage of that, and construct an array with the target size.

Summary: Now that the minifier is integrated inside the transformer, we can expose the param in the `buildGraph` method

Summary:
When moving the minification to the worker, I forgot to also minify JSON files (they have an early return).
This diff fixes this :)

Summary:
Since Babel is still in beta and breaking changes may happen between beta versions we need to lock this down and carefully consider upgrades.
For example, between .40 and .44 there seem to be at least two new mandatory options and who knows what else.
Once Babel 7 leaves beta we can go back to the caret (^).

Summary:
This commit refactors the metro bundling logic to make the traversal of dependencies much more generic, to not depend on any assumption regarding dependency resolution, haste, or even about the transformer/caching system.
So, the actual API of the `DeltaBundler` module (which will be extracted as a separate package in the near future) ends up being like this:
```
const graph = await deltaBundler.buildGraph(
['/root/entryPoint1.js', '/root/entryPoint2.js', /* ... */],
{
dependencyResolver: (from, to) => require('resolve').sync(to, {from}), // Use the standard nodejs resolver
transformFn: filePath => await transformFileUsingWhateverIPrefer(filePath),
},
);
```
The only part that is still coupled with the `DependencyGraph` is the file listener (which is tied to JestHasteMap via `DependencyGraph`), which is going to be decoupled soon.
From here, and once we have the new caching system fully rolled out and the old cache logic removed, we'll incorporate `jest-worker` and the caching system directly into the build graph logic, to end up extracting the whole `DeltaBundler` logic into its own package.
From there we can potentially reuse it to create simpler/more focused bundlers for web/etc.
