Summary: It seems we don't need that one much anymore, as we have a FS-based cache for files, and removing the last callsites doesn't really change perf, as we have to read these files eventually (plus some of these are read from `HasteMap`, that I believe is already dead code).

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.

Summary:
There is a bug with IP detection on Macs that have (1) multiple ethernet interfaces, (2) are using the second or third interface as their primary connection and (3) have extra loopback IPs configured (for example when running OpenVPN, running some Docker configurations or other more exotic applications). In those cases, automatic IP detection will falsely detect the IP as something like `127.94.0.1`, which will make it impossible to run debug builds from a physical device.
The underlying network configurations looks something similar to this (irrelevant parts omitted):

Summary:
When running an app on a real iPhone in debug mode, I occasionally get issues when trying to load the js bundle and I suspect the issue is with xip.io (and it doesn't look like I'm the only one: https://github.com/facebook/react-native/issues/12786https://github.com/facebook/react-native/issues/9688#issuecomment-272591839). So I've added the ability to optionally disable the use of xip.io if an env variable `DISABLE_XIP` is set.
Add `export DISABLE_XIP=true` to the `Bundle React Native code and images` build phase. Run the app on a real iPhone and ensure that it can load the JS bundle from the host computers IP.

Summary: This removes the call to `HasteFS#matchFiles()`, that has linear complexity. Instead, we index all the files by directory from `HasteFS` once loaded, a linear operation. Then, we can filter files from a particular directory much quicker.

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`.

Follow up to #13248 for iOS.
This pull request allows changing the default path to `cli` when running from Xcode environment. That is especially useful when debugging from a different location or... running `Haul`.
Set `export CLI_PATH=./node_modules/react-native/local-cli/cli.js` and run. Should use new path provided.

This PR depends on #13172
Packager events are mostly logged through the TerminalReporter by default (#13172 makes this configurable). But there are a few things that aren't passed through TerminalReporter.
- We [log a banner with some information about the port and what's going on](8c7b32d5f1/local-cli/server/server.js (L22-L32))
- Also [a message about looking for JS files](8c7b32d5f1/local-cli/server/server.js (L34-L38)) (not sure what that is for / if it is useful beyond telling the user what directory root they started the packager in, but that's another thing).
- If the packager fails to start, then [we log an error message](8c7b32d5f1/local-cli/server/server.js (L41-L61)).
This pull request changes those log messages to be handled by TerminalReporter. I tri

Summary: At FB we log errors into the error infra, and these errors are not actionnable for end users, so let's reduce the noise generated on the terminal. In the OSS case, people can simply add a handler in a TerminalReporter decorator, the same way we do internally (anyhow, I do not know of anyone using the global cache in OSS for now).
