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:
One of my changeset broke the "ModuleGraph" code without warning earlier because we are using `any`, that equivalent to having no typing at all. 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`.

Summary:
This is a simple one line change. When a red box is launching the editor, if `launchEditor.js` is aware of your editor it can also add a line number to open the file at. So if the stacktrace shows an error on like 56 in `ako.js` then it'll try`wstorm /Users/somelady/src/project/ako.js:56` instead of `wstorm /Users/somelady/src/project/ako.js`.
This adds PyCharm's command line launcher, which is named `charm`. There is existing logic to handle other JetBrains editors, so I just did a simple one line addition.
**Test plan (required)**
* Install PyCharm (if needed)
* Set environment variable `REACT_EDITOR` to `charm`
* Open PyCharm
* Add/replace the current `charm` command via `Tools -> Create Command-line launcher...` in PyCharm.
* Run a React Native project with an error in the source code.
* In the generated red box, click on one of the entries in the stack trace
* File should open in PyCharm at the correct line number.

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!)

- "Copy" button copies all the messages shown in the redbox to the host system clipboard, the solution is posting redbox messages to packager and the the packager copies the messages onto the host clipboard.
- "Dismiss" button always exits the redbox dialog.
- Add shortcut as "Dismiss (ESC)" and "Reload (R, R).
Notice: Copy button is only supported on Mac OS by now (warning in packager on other platforms), because it's not easy for us to test on Windows or Linux. Will put the codes for other platforms on Github issues, hoping anyone could help test and add this feature, then send us a pull request.

Summary:
When opening a text editor from react native there are a list of editors being supported. This PR adds `VSCode` to that.
As a difference with the current supported editors, `VSCode` has a notion of `workspace` (a directory that contains all of the project's files). The `workspace` can be passed to `VSCode` as a parameter so that if the workspace is already open we don't get new instances of `VSCode` every time a new file is open. The `workspace` is gotten by comparing the file location with the different `project roots`.
This code relies on `VSCode`'s `code` command, which it's documentation can be found at: https://code.visualstudio.com/Docs/editor/codebasics#_launching-from-the-command-line

Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.
Original Description:
Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

This allows us to extract dependencies added by transforms (and to avoid including them manually).
It also allows for better optimization and to get rid of the “whole program optimization” step:
This diff utilizes the new worker introduced in D2976677 / d94a567 – that means that minified builds inline the following variables:
- `__DEV__` → `false`
- `process.env.NODE_ENV` → `'production'`
- `Platform.OS` / `React.Platform.OS` → `'android'` / `'ios'`
and eliminates branches of conditionals with constant conditions. Dependency extraction happens only after that step, which means that production bundles don’t include any modules that are not used.

We think the problem is that watchman delays sending the file change notification because the system is under heavy use. It worth mentioning this is not a watchman issue!. This could happen for instance if flow is enabled. So, to better understand what's going on lets log when a file is changed and just before sending the HMR update to the client.

Summary:

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

We should further improve this on the future by showing the actual stacktrace instead of the `HMRClient` one. Also, we need to integrate this with the dev plugin that opens in the default editor the file/line the user clicks on.

Summary:

Fixes a terrible bug due to which when Hot Loading enabled when the user reloads we'll serve them the first `hot` bundle he requested. This happened because when HMR enabled we bailed out after sending the HMR updates and didn't rebuild any of the bundles the user requested before. As a consequence, when they reload we'd sent him the first and only one we ever built.
The fix is to tweak the hmr listener to return a promise. This way we can run the remaining code on the file change listener just after the HMR stuff finishes. We need to do it this way to avoid the remaining stuff to compete for CPU with the HMR one and give the best possible experience when HMR is enabled.

We're not planning to accept file removals in the short term on the HMR interface so lets bail when a file is removed (before this this we were throwing when trying to get the shallow dependencies).

Summary:

Before this diff we were only accepting the module that was modified but the user. This works fine as long as the user doesn't modify the dependencies a module has but once he starts doing so the HMR runtime may fail when updating modules' code because they might might a few dependencies. For instance, if the user changes the `src` a `Image` has to reference an image (using the new asset system) that wasn't on the original bundle the user will get a red box. This diff addresses this by diffing the modules the app currently has with the new ones it should have and including all of them on the HMR update. Note this diffing is only done when the we realize the module that was modified changed it's dependencies so there's no additional overhead on this change.

Summary:
public
Before this this when a file was changed besides sending the HMR update we rebuild every single bundle that the packager had build (to serve it faster when the user hit cmd+r). Since when hot loading is enabled we don't do cmd+r all this work was pointless (except for when you're developing multiple apps using the same packager instance at the same time, which we can assume is very uncommon). As a consequence, the HMR update was competing with the rebundling job making HMR quite slow (i.e.: on one huge internal app it took up to 6s for the HMR changes to get applied).
So, this diff tweaks the file change listener so that we don't rebundle nor invoke the fileWatchers (use for live reload which is also useless when hot load is enabled) when hot loading is enabled. Also, it makes the HMR listener more high pri than the other listeners so that the HMR dev experience is as good as it can get.

Summary:

Implement all the necessary glue code for several diffs submitted before to get Hot Loading work end to end:
- Simplify `HMRClient`: we don't need to make it stateful allowing to enable and disable it because both when we enable and disable the interface we need to reload the bundle.
- On the native side we introduced a singleton to process the bundle URL. This new class might alter the url to include the `hot` attribute. I'm not 100% sure this is the best way to implement this but we cannot use `CTLSettings` for this as it's are not available on oss and I didn't want to contaminate `RCTBridge` with something specific to hot loading. Also, we could potentially use this processor for other things in the future. Please let me know if you don't like this approach or you have a better idea :).
- Use this processor to alter the default bundle URL and request a `hot` bundle when hot loading is enabled. Also make sure to enable the HMR interface when the client activates it on the dev menu.
- Add packager `hot` option.
- Include gaeron's `react-transform` on Facebook's JS transformer.
The current implementation couples a bit React Native to this feature because `react-transform-hmr` is required on `InitializeJavaScriptAppEngine`. Ideally, the packager should accept an additional list of requires and include them on the bundle among all their dependencies. Note this is not the same as the option `runBeforeMainModule` as that one only adds a require to the provided module but doesn't include all the dependencies that module amy have that the entry point doesn't. I'll address this in a follow up task to enable asap hot loading (9536142)
I had to remove 2 `.babelrc` files from `react-proxy` and `react-deep-force-update`. There's an internal task for fixing the underlaying issue to avoid doing this horrible hack (t9515889).

This diff adds infra to both the Packager and the running app to have a WebSocket based connection between them. This connection is toggled by a new dev menu item, namely `Enable/Disable Hot Loading`.

Summary:
The JavaScript ecosystem doesn't have the notion of a built-in native module loader. Even Node is decoupled from its module loader. The module loader system is just JS that runs on top of the global `process` object which has all the built-in goodies.
Additionally there is no such thing as a global require. That is something unique to our providesModule system. In other module systems such as node, every require is contextual. Even registered npm names are localized by version.
The only global namespace that is accessible to the host environment is the global object. Normally module systems attaches itself onto the hooks provided by the host environment on the global object.
Currently, we have two forms of dispatch that reaches directly into the module system. executeJSCall which reaches directly into require. Everything now calls through the BatchedBridge module (except one RCTLog edge case that I will fix). I propose that the executors calls directly onto `BatchedBridge` through an instance on the global so that everything is guaranteed to go through it. It becomes the main communication hub.
I also propose that we drop the dynamic requires inside of MessageQueue/BatchBridge and instead have the modules register themselves with the bridge.
executeJSCall was originally modeled after the XHP equivalent. The XHP equivalent was designed that way because the act of doing the call was the thing that defined a dependency on the module from the page. However, that is not how React Native works.
The JS side is driving the dependencies by virtue of requiring new modules and frameworks and the existence of dependencies is driven by the JS side, so this design doesn't make as much sense.
The main driver for this is to be able to introduce a new module system like Prepack's module system. However, it also unlocks the possibility to do dead module elimination even in our current module system. It is currently not possible because we don't know which module might be called from native.
Since the module system now becomes decoupled we could publish all our providesModule modules as npm/CommonJS modules using a rewrite script. That's what React Core does.
That way people could use any CommonJS bundler such as Webpack, Closure Compiler, Rollup or some new innovation to create a JS bundle.
This diff expands the executeJSCalls to the BatchedBridge's three individual pieces to make them first class instead of being dynamic. This removes one layer of abstraction. Hopefully we can also remove more of the things that register themselves with the BatchedBridge (various EventEmitters) and instead have everything go through the public protocol.
