Summary: This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change. See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail. [General] [Changed] - Migrate "Libraries" from Haste to standard path-based requires Pull Request resolved: https://github.com/facebook/react-native/pull/24749 Differential Revision: D15258017 Pulled By: cpojer fbshipit-source-id: a1f480ea36c05c659b6f37c8f02f6f9216d5a323
