Since we no longer have externally configured "process" methods, I just inlined all of those. The main thing in this refactor is that I just inlined all the error branches into just `emitErrorChunk`. I'm not sure why it was split up an repeated before but this seems simpler. I need it since I'm going to be doing similar copies of this.
react-server
This is an experimental package for creating custom React streaming server renderers.
Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.
Use it at your own risk.
