Land Lanes implementation in old fork (facebook#19108)
Browse files Browse the repository at this point in the history 
* Add autofix to cross-fork lint rule

* replace-fork: Replaces old fork contents with new

For each file in the new fork, copies the contents into the
corresponding file of the old fork, replacing what was already there.

In contrast to merge-fork, which performs a three-way merge.

* Replace old fork contents with new fork

First I ran  `yarn replace-fork`.

Then I ran `yarn lint` with autofix enabled. There's currently no way to
do that from the command line (we should fix that), so I had to edit the
lint script file.

* Manual fix-ups

Removes dead branches, removes prefixes from internal fields.  Stuff
like that.

* Fix DevTools tests

DevTools tests only run against the old fork, which is why I didn't
catch these earlier.

There is one test that is still failing. I'm fairly certain it's related
to the layout of the Suspense fiber: we no longer conditionally wrap the
primary children. They are always wrapped in an extra fiber.

Since this has been running in www for weeks without major issues, I'll
defer fixing the remaining test to a follow up.
