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 :)

Summary:
This fixes a `Attempt to get native tag from node not marked as "native"` error that happens because some animated values are not converted to native before calling the base class `__makeNative`. This makes sure we call the `__makeNative` method of input nodes before calling `super.__makeNative`.
**Test plan**
Tested that it fixes the issue I encountered and that native animations still work with properly in RNTester.

Summary: Allows video uploads from native iOS by using the proper network handler, `RCTAssetsLibrary` rather than `RCTImageLoader`. Currently, uploading a camera roll video via its `assets-library://` URI would upload the first image frame. This fixes it by checking if the `assets-library://` URI is of the extension `MOV`, and if so, declines to process it from `RCTImageLoader`.

Summary:
This uses `context` to render inner lists of the same orientation to a plain `View` without
virtualization instead of rendering nested `ScrollView`s trying to scroll in the same direction,
which can cause problems.

Summary:
In <= 0.44, the default implementation of getProjectRoots() came from `local-cli/core/default.config.js`. With changes happening in the CLI and the packager over the course of the last two months, various pieces of this logic (specifically `local-cli/utils/Config.js`) were rewritten, and though default.config.js was still being imported and used in `local-cli/core/index.js`, the default `getProjectRoots()` was being overriden by the defaults specified in `local-cli/utils/Config.js`.
This PR moves the logic from default.config.js into Config.js and index.js, as appropriate. Specifically:
- The `getProjectCommands()`, `getProjectConfig()`, and `getDependencyConfig()` methods, which have traditionally not been part of the rn-cli.config.js spec, are now defined in `local-cli/core/index.js`.
- The `getProjectRoots()` method, which contained logic for properly resolving the _actual_ project root as well as resolving symlinks within that root, has been moved to `local-cli/utils/Config.js`, to match the fact that other default rn-cli.config.js definitions live there.

Summary:
This is necessary to fix an extraneous warning when a VirtualizedList is constructed on the first frame.
On the first frame, the dt is huge (ie, time since epoch).
On the second frame (which may legitimately be slow as a result of a lot to render), it will then assume there were two consecutive slow frames, and print a warning:
"VirtualizedList: You have a large list that is slow to update..."

Summary: Optimize ScrollView by adding flag "DEPRECATED_sendUpdatedChildFrames" to gate whether updatedChildFrames data is computed and propagated on scroll events. The frame data is used in ListView by the onChangeVisibleRows prop. When this prop is not defined, unnecessary computation in ScrollView should not be performed.

Summary:
Finally, a place where `Button` is properly introduced. This is based on the old Handling Touches guide, which has been simplified (with some content moved over to the scroll views tutorial).
I've also updated the ordering of the guides into something that makes more sense to someone just getting started with React Native.
