Summary: This removes the single-use "garbage collection" class and make a single `TransformCache` instead. The reason for doing this is that I'd like to experiment with using a local dir based on the root path instead of the `tmpdir()` folder, because on some platform using the temp dir is subject to permissions problem, sometimes it is empty, and on all platform it is vulnerable to concurrency issues.

Summary: I'm continuing my changes to avoid `lstat`-ing the folders when we don't really need to. That changeset in particular proposes to remove the check in `_loadAsDir`. The rationale is that right after that we try for the presence of the `package.json`. If that file exists, the folder necessarily exist so we can switch these two `if` blocks for sure without changing the logic. Finally, at the end we look for the "index" file. By removing the folder check, packager would now report "file `foo/index` does not exist" rather than "directory `foo` does not exist" if the folder does not exist. I think it's not much worse, especially as both of these are unhelpful for what I believe to be a large number of cases already anyway. Indeed, the whole algo is based on a series of try/catch, and only the very last try will see its error surfaced. But, most often, it'd be useful for earlier tries to be surfaced to the user. I do want to improve that; meanwhile, however, I sense it's not a big deal to remove that folder check for all these reasons. If you don't agree, I do have another proposition: we could catch errors generated by the last `_loadAsFile` call, and rethrow them as directory errors instead (if `dirExists` return `true`). That way, the call to `dirExists` would only happen in case of errors (but that could still happen quite a lot as a result).

Summary: I think we don't really need to check the directory beforehand, the function to find asset will just return an empty array. As for the error message, I tried adding a require of an asset file somewhere, but due to the way the ResolutionRequest algo work, it generates a final error message that unrealted ("Directory ... does not exist", instead of the "asset does not exist"). I plan to revamp the way errors are handled such as the error message clearly identifies what file paths have been inspected.

I have a need to bundle a pre-optimized external lib with my RN application. Until RN 0.42 I had been using a .babelignore to prevent the packager from trying to optimize this file and choke.
It seems in 0.42 and higher I'm no longer allowed to ignore the file.
This issue has also been reported as #12071
Details on the reasoning for this patch can be found in the issue I originally filed: https://github.com/facebook/react-native/issues/13168
What existing problem does the pull request solve?
This PR restores the functionality with babel ignoring files that existed in 0.41 before this patch:
0849f84df2 (diff-4676ea0b3c55c65c3929aa993144f07f)
Here's a screenshot of this patch properly ignoring the file I referenced in https://github.com/facebook/react-native/issues/13168 to be ignored.
The patch relies on the `ignored` value of the call to `babel.transform` and if true returns the src in a object per instruction from loganfsmyth from BabelJS core team.
To test, add a file to the `ignore` array of a `.babelrc` file in a React Native project with this fork.
I was unable to locate a test file for the transformer.js

Summary:
I suggest we grab our own version of worker-farm, since there are a few changes we'd like to do. There are two reasons for forking:
* the original project does not seem maintained anymore, with a PR remaining unanswered (https://github.com/rvagg/node-worker-farm/pull/42);
* we don't need to keep the level of genericity of the original project: for example, we don't need the option `maxConcurrentCallsPerWorker`, that we always keep to one.
Forking gives us opportunity to simplify the code for our use case. Later on we could reuse it for other projects such as `jest`.
A few things we'd like to do:
* remove special node options from the forks, such as `--inspect`, or even, allow adding special options (if you want to debug a worker specifically for example);
* allow us to pipe `stdout` and `stderr` instead of having transform spit stuff out to the parent process output;
* remove code managing `maxConcurrentCallsPerWorker` and clean up the code in general;
* add `flow` typing.

* Include the UID in the hash, so that different users have different folders for sure, and that we reduce potiential permissions issues. `tmpdir()` already returns a folder that's user-specific on OS X, but this is not a guarantee on all platforms.

Summary:
Note: if this changeset causes some breakage, consider disabling rather than reverting. To disable, the call to `_preprocessPotentialDependencies` in `ResolutionRequest` can be removed.
It's a bit of an experiment. I couldn't see any particular regression caused by this, but I could see net improvement of the global cache performance, as it unlock much, much stronger batching: indeed, instead of discovering dependencies progressively, we synchronously figure out the list of all potential modules of a bundle, and kick-off cache fetching and/or transformations. So when it comes to fetching from the global cache, it'll do less requests, and each requests will ask for considerably more keys at a time.
Potential problem caused by this changeset: if a module's dependencies completely changed, then the first time we try to build the bundle it'll start transforming modules that we probably don't care at all anymore, spending precious CPU time for nothing. I've been thinking about it and I cannot see such a case happening much often. Even if it happens, it should not cause any bug or corruption, it would just take additional time.
Other potential problem: that this new code doesn't handle some types of edge cases. It's quite hard to figure out what could possibly break in the `ResolutionRequest` code (and I think it would benefit from a larger refactor). We do have a good test coverage for `DependencyGraph` and it seems to work smoothly, so I'm relatively confident we're not breaking edge cases.

There is a bug with IP detection on Macs that have (1) multiple ethernet interfaces, (2) are using the second or third interface as their primary connection and (3) have extra loopback IPs configured (for example when running OpenVPN, running some Docker configurations or other more exotic applications). In those cases, automatic IP detection will falsely detect the IP as something like `127.94.0.1`, which will make it impossible to run debug builds from a physical device.
The underlying network configurations looks something similar to this (irrelevant parts omitted):

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`.

This changeset removes the `bundleOpts` to solve that issues. Instead, it makes the options explicit so that there is less uncertaintly. I love making options explicit, because they force callsites to take a consicious decision about what is really needed, making them more robust. They also expose oddities that probably needs refatoring, for example having a `resolutionRequest` in the bundle options does not seem correct, it should be an implementation details. Likewise, `onProgress` should probably be exposed differently, as it does not affect the content of the bundle itself.

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.

Summary:
This moves the `src` directory one level up and removes the `react-packager` folder. Personally, I always disliked this indirection. I'm reorganizing some things in RNP, so this seems to make sense.
Not sure if I forgot to update any paths. Can anyone advice if there are more places that need change?

Summary: We can simplify as there's only one option, and it seems to me we can also make it required, as otherwise the `JSTransformer` is essentially doing nothing. I don't believe we still have use cases where no transform happens at all, even in OSS?
