Summary:
React Native bundler (aka Metro Bundler) was splitted from the main codebase some time ago (now it lives [[https://github.com/facebook/metro-bundler|here]]). To make it more agnostic, polyfills will be moved out from it, so people who doesn't need them does not include them. However, RN will still need them, so the first step is to copy them back to RN so that we can provide them to Metro Bundler later.
We also include a way of passing the list of polyfills to include, as an `Array<string>`. The field is called `polyfills`, and defaults to the traditional list that is currently included in the package manager [see here](be1843cddc/packages/metro-bundler/src/defaults.js (L27-L37)).
In future commits, `metro-bundler` will be able to manage the `polyfills` array passed to it, and use it, instead of the pre-defined ones.

Summary:
This diff cleans up some cruft and adds some features:
* It removes the usage of an env variable to control workers.
* It removes the lazy and handwavy calculation on how many workers to use for jest-haste-map. Jest itself uses the maximum amount of workers available and it has never been reported as an issue – especially since it is a one-time startup cost of about 3 seconds on a cold cache only.
* It adds a `--max-workers` flag to replace the env variable. This one is able to control both the number of workers for `jest-haste-map` as well as the transformers.
* It makes the transformers run in the parent process if 1 or fewer workers are are specified. This should help with debugging.
Once you approve this diff, I will publish a new version of metro to npm and update the version used in RN and remove the use of the env variable altogether: https://our.intern.facebook.com/intern/biggrep/?corpus=xplat&filename=&case=false&view=default&extre=&s=REACT_NATIVE_MAX_WORKERS&engine=apr_strmatch&context=false&filter[uninteresting]=false&filter[intern]=false&filter[test]=false&grep_regex=
Note: the process of adding a CLI option is really broken. Commander also has a weird API. We should consider building a better public API for Metro and then consider how to build a new CLI on top of it and simplify our internal integration. I really don't like how Metro is integrated across pieces of the RN cli in ways that is hard to manage. But that is a larger task for another time :)

Summary:
* Internally, we already set up babel before calling into metro-bundler.
* Externally, I moved the setup calls to outside the packager/ folder.
If somebody has a custom integration with RN, they would need to setup babel themselves up until we make the open source split. By the time this is released in open source, an npm version of metro-bundler will be available for use.
Next step: also do this for the worker and remove setupBabel from the metro repo.

Summary:
After examining how React Native sets up `process.env.NODE_ENV` using `global.__DEV__` from `prelude_dev.js` or `prelude.js` by treating them like polyfills I decided to use the same approach for environment variables. I setup my own rn-project.config.js file like so:
```
const blacklist = require('react-native/packager/blacklist');
const pathJoin = require('path').join;
module.exports = {
getBlacklistRE: function() {
return blacklist([/build\/.*/, /app\/assets\/webpack.*/]);
},
polyfillModuleNames: [pathJoin(__dirname, 'globals.js')]
};
```
I ran the packaging server using:
`react-native start --config=config/react-native/rn-project.config.js --reset-cache`
I expected my polyfillModuleNames to be passed into the Packager properly and be handled the same way the built-in polyfills worked. Unfortunately I noticed the Packager wasn't actually getting `opt.polyfillModuleNames`. Digging into the code a bit, it seems the local-cli wasn't passing the polyfillModuleNames from the config.
There are no specs for runServer.js but this change can be tested by using a config that contains polyfillModuleNames. Sample config and run command provided above simple `global.js` provided below:
```
global.process = global.process ? global.process : {};
global.process.env = global.process.env ? global.process.env : {};
global.process.env['PROJECT_ENV'] = 'staging';
```

Summary:
In Expo tools such as XDE, exp we listen listen to stdout from the packager process and print it in our own buffer. In the case of XDE, an electron app, our log pane is DOM-based, and before printing each log chunk we need to remove special tty characters and sometimes parse it to get information that we need (eg: progress bar). By using a custom reporter, we can take the raw events and pass them along in a format that is easy to consume by XDE and exp. This same motivation applies to create-react-native-app, where we currently don't show a progress bar in the terminal, but we can with this change.

Instead of exposing a `getTransformOptionsModulePath` function in configurations, we can simply expose a `getTransformOptions` *function*. The necessity of exposing a path comes from the olden days, where we had a server listening on a socket, and a client, talking to that server.
Since that architectural gem no longer exists, we can use functions directly, rather than passing paths to modules around.

Summary:
This is the next incremental step to rewrite node-haste. I apologize for the size of this diff but there is really no smaller way to do this. The current architecture passes a single file watcher instance into many classes that each subscribe to file changes. It's really hard to keep track of this. The new implementation reduces the listeners to two (will eventually be just one!) - one in DependencyGraph and one in it's parent's parent's parent (ugh! This doesn't make any sense). This should make it much more straightforward to understand what happens when a file changes.
I was able to remove a bunch of tests because jest's watcher takes care of things like ignore patterns. Some of the tests were specifically testing for whether the change events were invoked and they are now much more straightforward as well by manually invoking the `processFileChange` methods.

Summary:
Add "Copy" and "Dismiss" button when the RN Android redbox is shown, consistent with that in RN iOS.
- "Copy" button copies all the messages shown in the redbox to the host system clipboard, the solution is posting redbox messages to packager and the the packager copies the messages onto the host clipboard.
- "Dismiss" button always exits the redbox dialog.
- Add shortcut as "Dismiss (ESC)" and "Reload (R, R).
Notice: Copy button is only supported on Mac OS by now (warning in packager on other platforms), because it's not easy for us to test on Windows or Linux. Will put the codes for other platforms on Github issues, hoping anyone could help test and add this feature, then send us a pull request.
Redbox Dialog in RN Android before:

- We can adjust the button styles in redboxes.

That way they don't have to fork various parts of the iOS and Android build system that React Native already provides just to add a `--transformer` command line argument.
**Test plan:** Applied this patch to the React Native version in my app, implemented `getTransformModulePath()` in my `rn-cli.config.js`, and verified that my custom transformer is invoked.

Summary:
When opening a text editor from react native there are a list of editors being supported. This PR adds `VSCode` to that.
As a difference with the current supported editors, `VSCode` has a notion of `workspace` (a directory that contains all of the project's files). The `workspace` can be passed to `VSCode` as a parameter so that if the workspace is already open we don't get new instances of `VSCode` every time a new file is open. The `workspace` is gotten by comparing the file location with the different `project roots`.
This code relies on `VSCode`'s `code` command, which it's documentation can be found at: https://code.visualstudio.com/Docs/editor/codebasics#_launching-from-the-command-line

Summary:
public
The packager currently assumes that all assets that are not JSON or JS files must be images. Although it is possible to add other extension types, they crash the packager if you try to require them, because it attempts to get their dimensions, assuming that they are an image.
This is a crude workaround for that problem, which skips the image-specific processing for non-image assets, but really it would be better if the packager was properly aware of different asset types and treated them differently (e.g. for sounds it could include the duration, for HTML pages it could parse and include linked CSS files, etc).
I've also added an example of using `require('...')` to load a packager-managed HTML page in the UIExplorer WebView example. In future I anticipate that all static asset types (sounds, fonts, etc.) could be handled in this way, which allows them to be edited or added/removed on the fly instead of needing to restart the app.
