Summary:
Fix the `path.sep` replacement for Windows, currently it just replace one segment:
```js
// Result: './lib/random\random-byte.js'
'./lib\\random\\random-byte.js'.replace(path.sep, '/')
```
Change to regex will work fine:
```js
// Result: './lib/random/random-byte.js' (correct)
'./lib\\random\\random-byte.js'.replace(new RegExp('\\' + path.sep, 'g'), '/')
```

Summary:
`declareOpts` is weakly typed. Since the callsite of Resolver constructor is itself flowifyed, we can get rid of `declareOpts`, and this provides us with much better typing.
Eventually I'd like to get rid of most of the defaults in the packager's inner code (ex. `watch` being false, `dev` being true). The reason is that defaults everywhere are prone to causing inconsistencies (for ex. some other code could have `dev` as false by default), problems that cannot be caught by Flow. Instead of having non-required options, I believe it is more sensible to provide helper functions that build sets of default options.

Summary:
This code is a bit sloppy, I need to rethink about it. So I prefer to remove it altogether for now.
The problem with this is that it is disabling the global cache "put" operations at the same time, so the script supposed to update the cache actually doesn't do the job past the fist few hundred files. This defeats the purpose of the global cache.

Summary:
This changes the way that module identifiers are replaced with numeric ids so that ids are padded with spaces on the right to take up the same space as the original string literal.
By doing this, we keep the mappings for the generated source line intact.
```
// original source
const React = require('react');
// old replacement
const React = require(12 /* react */);
// new replacement
const React = require(12 ); // 12 = react
```
The remaining edge case are module names that are replaced with numeric IDs that are longer than the replaced string, e.g.:
```
const Q = require('q');
const Q = require(1234);
```

Keep track of the number of cache misses. If we have a series of misses but then we
start seeing hits, then we progressively reset the counter. If there are too many misses, we just give up on the global cache.

Summary:
This changes the callback value of `Graph` function so that it also contains a separate property with `Module` instances of the entry points.
Having references to the entry point modules allows to e.g. create require calls to them dynamically to kick of bundle execution.
The commit also contains a refactoring of the `Graph` function and its helpers that reduces the need for extensive parameter passing and long nested functions.

Summary:
6554ad5983ae85212684a09869e2ea2e0b743dd3 broke assets on windows, this fixes it and add a test to avoid regressions.
Ideally we'd run all the Dependency graph tests on both posix and win32 filesystems but that would probably require doing some sort of factory function to create the tests because I don't think we want to duplicate every test (file is big enough already :)). So for now I just copied that one test and changed the paths manually.
**Test plan**
Run the new test without the fix -> fails
Run the new test with the fix -> succeeds

Summary:
This kills fastfs in favor of Jest's hasteFS. It gets rid of a ton of code, including the mocking code in ResolutionRequest which we don't need any more. Next step after this is to rewrite HasteMap, ModuleCache, Module/Package. We are getting closer to a nicer and faster world! :)
Here is what I did:
* Use Jest's HasteFS instead of fastfs. A fresh instance is received every time something changes on the FS.
* HasteFS is not shared with everything any more. Only one reference is kept in DependencyGraph and there are a few smaller functions that are passed around (getClosestPackage and dirExists). Note: `dirExists` now does fs access instead of an offline check. This sucks but stat calls aren't slow and aren't going to be a bottleneck in ResolutionRequest, I promise! When it is time to tackle a ResolutionRequest rewrite with jest-resolve, this will go away. "It gets worse before it gets better" :) The ModuleGraph equivalent does *not* do fs access and retains the previous way of doing things because we shouldn't do online fs access there.
* Add flow annotations to ResolutionRequest. This required a few tiny hacks for now because of ModuleGraph's duck typing. I'll get rid of this soon.
* Updated ModuleGraph to work with the new code, also created a mock HasteFS instance there.
* I fixed a few tiny mock issues for `fs` to make the tests work; I had to add one tiny little internal update to `dgraph._hasteFS._files` because the file watching in the tests isn't real. It is instrumented through some function calls, therefore the hasteFS instance doesn't get automatically updated. One way to solve this is to add `JestHasteMap.emit('change', …)` for testing but I didn't want to cut a Jest release just for that. #movefast
(Note: I will likely land this in 1.5 weeks from now after my vacation and I have yet to fully test all the product flows. Please give me feedback so I can make sure this is solid!)

Summary:
The logic in `ModuleGraph/Graph` allowed the callback to be invoked twice, if two invocations of `resolve` call back with errors asynchronously.
This fixes that problem by always calling `queue.kill()` on the asynchronous queue, and only invoke the main callback from the `drain` and `error` queue callbacks.

Summary: For having a global cache, we need cache keys that are the same from different machines, so we cannot include user/machine-specific information. In that regard, I suggest we consider the paths relatively to the install directory of the React Native instead of being absolute, so that they are more chances they stay stables between different installations, users, machines.

Of course, the file could depend on other files we don't take into account... but the mtime solution was already problematic in that regard, so I assume this is a safe change.
