Summary:
There was an error with packager symbolization on Windows because it looks like `allowHalfOpen: true` doesn't work properly when using named sockets. This uses a random port on localhost for the connection instead on Windows as a workaround.
**Test plan**
Tested that symbolization works on both mac and windows by triggering a warning in UIExplorer.

- [x] Target the `master` branch, NOT a "stable" branch.
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
Fixes#12071, #13168

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.

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:
Two things in there:
* Using `base64` was kinda broken, as it can contain slashes, invalid in file names. It would still work however because it would just create a second level folder when doing `mkdirp`. Still I think it's better to fix that correctness.
* 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: Oftentimes packager stalls for several seconds after requiring a bundle, because it's busy cleaning up old cache files. We shouldn't do that when, for example, we just restarted packager. This changeset stores the micro-timestamp of the last collection so that we don't waste time next time.

Summary:
Don't build js bundles for debug simulator build configurations
Motivation:
We have more than one debug build configuration that we run in the simulator, and none of them are exactly named 'Debug'. We want to establish the convention that any simulator build configuration containing the word 'Debug' will not build the react js bundles. We believe this is less intrusive to the developer.

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.
