Summary:
This changeset moves the creation of the transform cache at the top-level of the bundler so that:
* we can use alternative folders, such as the project path itself, that I think will be more robust especially for OSS;
* we can disable the cache completely, that is useful in some cases (for example, the script that fills the global cache).
The reasons I believe a local project path is more robust are:
* there are less likely conflicts between different users and different projects on a single machine;
* the cache is de facto cleaned up if you clone a fresh copy of a project, something I think is desirable;
* some people have been reporting that `tmpDir` just returns nothing;
* finally, it prevents another user from writing malicious transformed code in the cache into the shared temp dir—only people with write access to the project have write access to the cache, that is consistent.

Summary:
Working on refactoring error handling in `_loadAsDir` I figured out it was oftentimes problematic to pass on the candidates out of the functions as an array, as in practice there's always a single "candidates" object passed out. Also, using an array prevented nice Flow typing and forced additional invariants to be added. So I replaced that by a return value that explicitely can be either a module, or resolution candidates. That way the semantic is more clear: we don't get any candidates if we did resolve properly, and at the same time we enforce returning candidates if we could not resolve any module.
At first I wanted to just have type `{module: TModule} | {candidate: TCandidate}`, but Flow would hit edge cases, so instead I added a field `type` that make it explicit what is the result of the resolution, and allows Flow to refine the type fully after we test that field. This allows us to remove the extraneous invariants. Also, a nice thing is that at a few places, even if the type of the candididate is different, Flow allows us to return the "resolved" object just as it is, that prevents using more memory and causing more garbage collection than necessary.
Since we're creating more objects with that solution, this will be slightly less performant than returning `Module` objects directly, but I don't think it is worth micro optimizing this at that point. If really we see this to be causing trouble later, I'd try to find solutions such as reusing a pool of objects. Ex. we could pass the result `Resolution` object as argument instead of returning a fresh one, but that would make the code less legible, more complex.

It was hard to type the resolution main algo, I had to put type annotations explicitely everywhere, otherwise Flow would get in some kind of loop and do weird errors. I think it's because the algo is recursive and Flow tries to infer types too deeply because of the generics.
Anyway, apart from that it's good to get this extra type security in the few other places. We require Node v4 minimum, that according to the internets supports the `class` syntax without transform, and I verified that inheriting from `Map` actually works as expected.

Summary: Default arguments are dangerous, and it shows here again. `Server` was calling that function without passing down the platforms, meaning custom platform would not be accounted for, possibly causing all kinds of bugs for OSS use cases. Additional, the typing of `platform` across the stack was wrong: it can be `null`, in which case we resolve the files without extension. The reason Flow didn't detect that issue before is because we use `Object.assign` to re-export the function from `DependencyGraph`, but Flow is not smart enough to propagate the types in that particular case. I'll remove all the other re-export, as it may uncover further type errors.

The reason is, if you try to require "foo.ios.png", the returned asset name would be "foo", and thus we'd try to find "foo.${ext}.png" where `ext` could actually be `android` or anything else!

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.

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.

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.

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.
