Summary:
By default, when Babel transforms a file, it looks for .babelrc in the file's directory and all parent directories until it finds a .babelrc file. This means that when Metro tries to transform `<PROJECT_ROOT>/node_modules/dep/mod.js`, it searches for `<PROJECT_ROOT>/node_modules/dep/.babelrc`. If that .babelrc actually exists, Babel will try to apply it.
In practice, this often causes problems because packages that include .babelrc often do so unintentionally -- they don't intend for the package consumer to look at that .babelrc file. One thing we've done a lot is `rm` all .babelrc files under node_modules -- this commit effectively achieves the same in a less destructive way by telling Babel not to look up .babelrc files. (To clarify, Metro will still apply the .babelrc file in the project root.)
Since the current behavior is to look at .babelrc files, this commit keeps that behavior for now. We'll consider overriding the default behavior (that is, making Babel not lookup .babelrc files) in the default configuration of Expo/RN projects. If this goes well and we empirically find that people are having a better time, we may want to consider flipping this option's default in Metro, so that Metro tells Babel not to look up .babelrc files by default.

Tested that it is possible to show bundle download progress in react-native using this header and added unit test.

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: Downgrade the locked version of Babel block scoping, kinda temporarily until we upgrade internally. This makes in on par with the version we use internally, so that the `basic_bundle` test had the same results on both infrastructures. This doesn't change a single thing for `metro-bundler` consumers, because this `yarn.lock` file is only used for testing/CI, not when the library is installed as part of a project.

Summary: I appears `Object.assign` is not properly typed-checked by Flow, and silently so, so I propose we switch to an explicit list until we find an alternative solution. I prefer to have strong typing especially for options, and as the lack of typing has caused breakage before.

Summary: I'd like to get rid of the function as blacklist, because it's impossible to process properly at the `jest-haste-map` level (https://github.com/facebook/jest/pull/4047). The reason we use a function in Metro bundler is because we excludes all the `__tests__` modules. However, I removed this exclusion completely, and I could build our package without any problem and with no difference in the final bundle. I can only assume, then, that this line is only here for slightly increasing performance. Therefore, I think it's reasonnable to move it as part of the default blacklist shipped with Metro bundler instead.

Summary: This put it on par with the version we use on other projects. This new version breaks assumptions about the way Promise/ticks/timers use to work, and I was not able to make it work properly synchronously. Since it's fragile anyway (because rely on Promise and feature internals), I propose the switch to async as done in this changeset. If `res.end` is not called, tests will just timeout instead.

Summary: Going one step further, we can start working around the throwing version. To simply some code, I also piggybacked the addition of helper functions `resolvedAs` and `failedFor` in this changeset, hope it's okay. I can split if necessary.

Summary:
This fixes https://github.com/facebook/react-native/issues/14530 on my local repro. The reason the original problem appears is because when requiring the preset itself, what I think is a bug in babel-register kicks in and it starts transforming the presets themselves. That fails because these preset don't actually have the correct transforms plugins installed/specified in their `package.json` (they do it at prepublish time).

Summary:
Remove our internal docbloc module and use `jest-docblock` instead.
The development server is using `jest-haste-map` exclusively, which in turn relies on `jest-docblock`, which differs slightly from our own docblock module.
Depending on only one version greatly reduces the number of edge cases

Summary:
We use custom npm scripts (`prepare-release`, `cleanup-release`) to
- move `src` to `src.orig`, and `build` to `src` before creating the tarball
- move everything back afterwards
We run these scripts with lerna before and after publishing. Custom hooks avoid problems with `prepublishOnly` and `postpublish` not being run at opportune times, `prepack` and `postpack` not being supported by npm v4 and yarn, and using `lerna run prepublishOnly` resulting in duplicated execution of the command.
This ensures that development is closer to what is pulled in from npm.
