_What existing problem does the pull request solve?_
On Linux, the packager caught an "Google Chrome exited with error: { Error: spawn google-chrome ENOENT}" when trying to launch the devTools because google-chrome is not installed but chromium is.
Thus, this pull request maps the platform Linux with chromium for launching the debugger automatically in the packager
_A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI or updates the website._
- enter on terminal
> react-native start
- launch the app in dev mode with "Debug JS remotely" enabled
- the packager prints "Launching Dev Tools..." and launch chromium with the debugger

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:
The React Native Remote Debugger page (`debugger.html`) contains an embedded silent sound file to maintain tab priority in Google Chrome.
This revision simply replaces the existing one with a better one that has the following characteristics:
- 1s Duration
- 10Hz Frequency
- -48dBFS Amplitude
- Fades in/out to reduce audible clicks on loop.
- 44.1kHz @ 16bit to maximimize compatibility.
- Smaller size.
Much thanks to Stephane Pigeon (http://stephanepigeon.com/) for designing the sound file specifically for this use case.

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:
`declareOpts` prevents strong Flow typing, and promotes default values, that may be different from a function to another (my goal is to remove defaults from the whole codebase except perhaps the public API). This changeset replaces it by Flow types and fixes callsites to be explicit on values.
This is the last callsite of `declareOpts` so I'll remove it, in a separate diff.

Summary:
One of my changeset broke the "ModuleGraph" code without warning earlier because we are using `any`, that equivalent to having no typing at all. This changeset fixes the types so that `ResolutionRequest` is exactly what it actually is: a class usable for any `Module`-looking class, including the normal one, and the "ModuleGraph" one used for Buck builds. That way, the ModuleGraph's `Module` is typechecked against `Moduleish`.
Concretely this change mostly migrates the `Module` to its generic parameter counterpart `TModule` inside `ResolutionRequest`.

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.
Create `LogReporter.js` in the root of a project with the CLI changes included in this PR.

Summary:
The middleware for automatically converting Systrace traces to HTML and popping the browser hasn't worked properly for a while, since the version on Homebrew generates some code that uses `Object.observe`, which was deleted from Chrome ages ago. People have complained about it, but fixing it properly has proven to be harder than expected, so I suggest we simply update the message with instructions for people to load it on Chrome, which is what all of us have been doing anyway (AFAIK).

Good news however,it was caught by the OSS e2e test, that covers Hot Reloading.
