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.

Summary:
BREAKING CHANGE
This change upgrades the React Native build pipeline from Babel 6 to Babel 7
If you use a `.babelrc` then you'll need to update it to Babel 7 (note that some plugins are no longer relevant, some plugins are automatically upgraded, and some will need some manual love).
Note that you may also need to upgrade your dev env, tests etc, to make sure they work with Babel 7.

Summary:
Here, we move `index.js` files in directories one level up, and rename them to `<dirname>.js`.
This makes for a more pleasant development experience, as files are easier to identify even when only seeing the file name.
It also eliminates quite some `../` segments in imports.

Summary:
Adds additional headers to delta responses:
- The next delta ID. This helps to defer parsing the delta payload to a different layer.
- The size of the delta. This can be used as a hint for memory allocation
