Summary:
Absolute imports on Windows were broken, I'm not 100% sure when this happens but when I tested Exponent on Windows which uses `rn-cli.config.js` with
```js
getTransformOptions() {
return {
reactNativePath: path.resolve('./node_modules/react-native'),
reactPath: path.resolve('./node_modules/react'),
};
}
```
it seemed to use absolute paths for these modules.
I also tested absolute paths in node repl and it does work for absolute paths of different formats. `C:/root/test.js`, `/root/test.js`, `C:\root\test.js` all do resolve properly to the same module.
To fix this I resolve the absolute path using `path.resolve` on Windows. Noop on other platforms to avoid the overhead since it's not necessary.
**Test plan**
- Tested that it fixed the bug I had when running Exponent on Windows.
- Updated the absolute path test to use forward slashes since this is what happens in practice when using `getTransformOptions`. We can't test all cases on linux since adding the drive letter au

Summary:
Similar to https://github.com/facebook/jest/pull/2877, this introduces an optional config `HasteImpl` of type `{getHasteName(filePath: string): (string|void)}` that returns the haste name for a module at filePath if it is a haste module or undefined otherwise.
This allows us to inject a custom implementation of haste's module id resolution rather than only relying on `providesModule` annotations

Summary:
Moves stack trace symbolication to a worker process.
The worker process is spawned laziliy, and is treated as an exclusive resource (requests are queued).
This helps keeping the server process responsive when symbolicating.

Summary:
HTTP request URLs don’t include protocol, host and port. Stack frames URLs, on the other hand, contain full URLs. These full URLs are used to get the correct bundle to build the source map from.
The method that creates option objects from URLs therefore now discards leading protocol, host and port to ensure that cached bundles can be reused for symbolication rather than triggering rebuilds.

Summary:
I extracted all the dependencies (using jest-haste-map) and copied them from the package.json in react-native to RNP. There is some duplication here for now but we can later go back and remove the duplicated dependencies from react-native that aren't needed there.
I also removed a mock file that hasn't been in use for a long time.

Summary:
The first time I tried to commit this changeset, it was causing many new packages to be installed, because the dependency would depend on newer versions that what we have installed. So, I had made a diff so upgrade all the babel packages. Unfortunately this caused some problem as the newer versions of Babel are more strict on some syntaxes. Of course, these have to be addressed, but I don't want this changeset to be coupled with Babel upgrades and the issues that arise from it.
So instead, I decided to install the slightly older version of the async-to-generator module. At first I tried with just doing:
yarn add babel-plugin-transform-async-to-generator@6.16.0
But, `yarn` is stubborn: because this module depends on a caret version of `babel-helper-remap-async-to-generator`, it installs the very last version of it, that itself needs more recent versions of other Babel modules. So, instead, I add to install a slightly older version of the dependency manually, then then the plugin:
yarn add babel-helper-remap-async-to-generator@6.16.0
yarn add babel-plugin-transform-async-to-generator@6.16.0
This allows us to have a `yarn.lock` with only a minimal amount of changes, and uncouple this change from any Babel upgrades. Because we only have a few new modules, the `node_modules` folder also stays the same, 133M, and it gives us confidence this will not cause significant startup time regressions.

Summary:
allow-large-files
By using async/await the code is (1) less nested, (2) more compact and (3) more robust (no exceptions running away, and much less risks of forgetting to call the callback/resolve, or mistakenly calling it twice). I now tend to think we could switch to it for all the callsites that are not in a perf-critical path.
I switched from 'request' to 'node-fetch' because 'request' has an annoying callback with 2 arguments. So it's simpler to use an interface that's (1) already returning a Promise and (2) that is becoming standard.
This changeset was a way for me to start experiment with introducing async/await in packager codebase, and it looks pretty good so far.

Summary: I figured out that the uncaught rejection that happens on transform error originated from a "fork" along the chain, where we both "then" on a promise, and return that promise. In that case Node.js, legitimately I think, identifies this as an uncaught rejection case. One solution, in this changeset, is to do the side-effects as part of the promise chain instead of "forking". Another option would be to add an explicit error handler to the additional "then", but it seems we don't have to handle that case here.
