Summary:
We use projectRoots to limit crawling of jest-haste-map in large codebases. Since this implies multiple projects roots, it makes it very hard (or impossible) to reliably cache dependency resolutions.
If we can replace this with a single project root and a set of watch roots, we can have relative path resolutions for all dependencies which van be cached.

Summary:
We have found that it is useful to work with production rather than dev bundles when working on e.g. performance and animation tuning.
For a larger app, `react-native bundle` with `--dev false` can get very slow due to minification - in our case, this was especially true of library code (e.g. the AWS SDK taking nearly 15 secs to minify on a top-spec MBP 15"). This is fine when just building every now and then, but when making frequent changes and rebuilding, it becomes quite painful.
Currently there is no way to perform a release (non-dev) build, with minification disabled. This PR adds an optional `--minify` flag to enable developers to disable minification, reducing build times significantly for our use case.
Checked output bundle size, to ensure behaviour stays the same as the existing default when `--minify` is not specified, and that the `minify` flag gets passed through to Metro bundler correctly if specified.

Summary: Tries to adress https://github.com/facebook/metro/issues/65. We need a reasonnable workaround to support modules like `moment.js` that do dynamic requires but only in some cases. By replacing the call by a function that throws, we move the exception at runtime instead of happening at compile time. We don't want to do that for non-node_modules file because they are fixable directly, while `node_modules` are not fixable by people and they get completely blocked by the error at compile time.

Summary:
`metro-bundler` v0.21 contains a rewritten bundling mechanism, with simplified logic and much faster rebuild times, called delta bundler. This release contains a couple of breaking changes:
* Now, when using a custom transformer, the list of additional babel plugins to apply are passed to the `transform()` method. These are used in non-dev mode for optimization purposes (Check 367a5f5db8 (diff-40653f0c822ac59a5af13d5b4ab31d84) to see how to handle them from the transformer).
* Now, when using a custom transformer outputting `rawMappings`, the transformer does not need to call the `compactMappings` method before returning (check d74685fd1d (diff-40653f0c822ac59a5af13d5b4ab31d84) for more info).
* We've removed support for two config parameters: `postProcessModules` and `postProcessBundleSourcemap`.

Summary: When we built packager asset system we were mostly concerned about images. However, this system can also be used to work with videos, animations and other binary resources. The code that sorts assets into Android resource folders currently just shoves all non-drawable resources under `drawable-mdpi`, which is not ideal. Talking to Android experts on the team, `raw` seems like a much better place for other resources.

Summary:
This diff cleans up some cruft and adds some features:
* It removes the usage of an env variable to control workers.
* It removes the lazy and handwavy calculation on how many workers to use for jest-haste-map. Jest itself uses the maximum amount of workers available and it has never been reported as an issue – especially since it is a one-time startup cost of about 3 seconds on a cold cache only.
* It adds a `--max-workers` flag to replace the env variable. This one is able to control both the number of workers for `jest-haste-map` as well as the transformers.
* It makes the transformers run in the parent process if 1 or fewer workers are are specified. This should help with debugging.
Once you approve this diff, I will publish a new version of metro to npm and update the version used in RN and remove the use of the env variable altogether: https://our.intern.facebook.com/intern/biggrep/?corpus=xplat&filename=&case=false&view=default&extre=&s=REACT_NATIVE_MAX_WORKERS&engine=apr_strmatch&context=false&filter[uninteresting]=false&filter[intern]=false&filter[test]=false&grep_regex=
Note: the process of adding a CLI option is really broken. Commander also has a weird API. We should consider building a better public API for Metro and then consider how to build a new CLI on top of it and simplify our internal integration. I really don't like how Metro is integrated across pieces of the RN cli in ways that is hard to manage. But that is a larger task for another time :)
