Jean Lauliac bfc0e8c26f packager: add preprocess for buck worker
Summary: For the Buck integration (work-in-progress), we want to add the ability to do some custom preprocessing similar to the packager server. The signature is different so I prefer to have a separate function for that. Also we don't need the transform options right now, I suggest we don't add them for now and add them later if necessary.

eacaps e53046b9ec pass polyfillModuleNames into packager
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.

- [x] Provide a **test plan** demonstrating that the code is solid.
- [x] Match the **code formatting** of the rest of the codebase.
- [x] Target the `master` branch, NOT a "stable" branch.

Currently if a custom scheme is specified, `run-ios` will fail with the following message

```

Karan Thakkar 840dc0cc82 Allow configuring the app source folder for android
Summary:
I have been working on integrating React Native into an existing app and realised that the source folder for android code is currently hardcoded as `app`. Being a legacy codebase we can't really change that. So I wanted to be able to customise this folder name so that I can integrate RN seamlessly and start it from the CLI without having to run it from Android Studio.

- Create a barebones RN app
- `react-native run-android` works successfully
- Refactor the name of the app folder inside the android directory to `TestFolderName` using Android Studio
- `react-native run-android` now fails
- Changing this command to `react-native run-android --appFolder=TestFolderName` works successfully

On windows, recent versions of local-cli will display a yarn error to stderr when starting the packager (see https://github.com/expo/xde/issues/91, https://github.com/react-community/create-react-native-app/issues/101, https://github.com/react-community/create-react-native-app/issues/113#issuecomment-289185491 for examples of users hitting this in the wild), even though no package management action is being taken.

From what I can tell this is what happens:

* [`local-cli/util/PackageManager.js` calls the above function when it's require'd](6fa87134fc/local-cli/util/PackageManager.js (L20))

Vojtech Novak cd4545f812 configurable devEnabled in React.gradle
Summary:
This PR adds support for configurable devEnabled option when building an android app. This is currently hardcoded.

The reason for making this configurable is this: I have an app that uses code-push and 3 buildConfigs. I want to have a debugging version which has `devEnabled = true`, then a staging version which has `devEnabled = false` (this version of the app is used internally for testing and should behave just like a release version of the app, and when the tests succeed the changes are promoted into the release version to the users out there, using code-push). The last version is a standard release version with `devEnabled = false`.

Currently, `devEnabled` is hardwired like this: `!targetName.toLowerCase().contains("release")` so by default my `staging` buildConfig will have `devEnabled = true` but I'd like it to be false.

With this PR it'd be possible to configure this as follows, while not breaking the current behavior.

Jean Lauliac 8755338728 packager: get rid of type `any` in ResolutionRequest
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`.

Thanks for submitting a PR! Please read these instructions carefully:

- [ ] Explain the **motivation** for making this change.
          Using React Native latest version with Cocoapods 1.2.0 causes the following error inside iOS app extensions

> /react-native/React/Modules/RCTAccessibilityManager.m:67:70: ‘sharedApplication’ is unavailable: not available on iOS (App Extension) — Use view controller based solutions where appropriate instead.

Moving the use of [UIApplication sharedApplication] to RCTSharedApplication() which is safe on app extension

        I am not sure how to test such that all the features which touch the modified code are tested.

- [ ] Match the **code formatting** of the rest of the codebase.
- [ ] Target the `master` branch, NOT a "stable" branch.

Brent Vatne b80e2c8799 Move packager initialization events to reporter
Summary:
This PR depends on #13172

Packager events are mostly logged through the TerminalReporter by default (#13172 makes this configurable). But there are a few things that aren't passed through TerminalReporter.

- We [log a banner with some information about the port and what's going on](8c7b32d5f1/local-cli/server/server.js (L22-L32))
- Also [a message about looking for JS files](8c7b32d5f1/local-cli/server/server.js (L34-L38)) (not sure what that is for / if it is useful beyond telling the user what directory root they started the packager in, but that's another thing).
- If the packager fails to start, then [we log an error message](8c7b32d5f1/local-cli/server/server.js (L41-L61)).

This pull request changes those log messages to be handled by TerminalReporter. I tri

Brent Vatne 5f5da4e122 Add support for custom log reporter cli option for local server
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.

```
class LogReporter {
  update(event) {
    console.log(JSON.stringify(event));
  }
}

module.exports = LogReporter;
```

Now, run `react-native start --customLogReporterPath=LogReporter.js` -- all of the raw events will be output as JSON (while the logs
