Summary: Internally we use `multipart/form-data` to upload transformed files to the global cache, using the keys as file names. Unfortunately the server would read that and consider only the basename as the key, not the full path. So we wouldn't store the data under the right key. This is definitely a bug in the way upload is implemented: we should transmit the keys separately. But, this changeset offers a quick mitigation by avoiding slashes in the key, so that the whole key is a valid base file name.

Summary:
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:
The existing resolution logic of assets:
* goes over all the files of the asset's directory for every resolution request;
* duplicates the parsing logic of `AssetPaths` by building up a custom regex for each resolution request.
This changeset proposes to tweak this by building an index for each particular directory in which we're looking for assets, so that we don't have to crawl a single directory twice, and so that it reuses the logic of `AssetPaths.tryParse()` for determining variants.

Summary:
Not only is this function is building a custom Regex for every single file, but it's also duplicating some of the work of the inner function, that is already splitting up the platform/extension. This changeset refactors both function to have a more strict and legible logic to extract asset information. We extract the base name first, then we extract the resolution from it, instead of rematching platform and extension.
I stumbled on this while looking into refactoring the asset resolution logic of `ResolutionRequest#_loadAsAssetFile()`. The next step would be to reuse the exact same function for resolving assets instead of using a custom regex there as well.

Summary: Add Flow types, revealing a few problems, such as `isHaste` having the wrong return value in the "pseudo-mocks". But since the buck worker is in fact working, I guess these functions were never called... The point of typing this file is that I'm going to start aggressively pruning dead code in `node-haste` and hopefully, eventually, get rid of `Moduleish` and `Packageish`.

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.

Summary: I stumbled on this while refactoring that function, and i realised that, I believe it doesn't make sense to take into account the platform extension of the "potiential" file path. 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! So it's confusing. There's no reason we should allow callsites to specify platform anyway I think. With this changeset we're not losing any functionality, but it might require people to fix some incorrect callsites.

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).
