* Add debug tools package
* Add basic implementation
* Implement inspection of the current state of hooks using the fiber tree
* Support useContext hooks inspection by backtracking from the Fiber
I'm not sure this is safe because the return fibers may not be current
but close enough and it's fast.
We use this to set up the current values of the providers.
* rm copypasta
* Use lastIndexOf
Just in case. I don't know of any scenario where this can happen.
* Support ForwardRef
* Add test for memo and custom hooks
* Support defaultProps resolution
`flow-coverage-report` stopped working after Flow was set to run for each renderer separately (#12846). As discussed in #13393, this is hard to fix without adding complexity to `.flowconfig`'s generation.
Remove 'async', 'bundle-collapser', 'del', 'derequire', 'escape-string-regexp', 'git-branch', 'gzip-js',
'merge-stream', 'platform', 'run-sequence' & 'yargs'.
Most of them were used in the old Grunt build system.
This ends up removing 32 packages, according to yarn.lock.
* Use native event dispatching instead of Simulate or SimulateNative
In #12629 @gaearon suggested that it would be better to drop usage of
`ReactTestUtils.Simulate` and `ReactTestUtils.SimulateNative`. In this
PR I’m attempting at removing it from a lot of places with only a few
leftovers.
Those leftovers can be categorized into three groups:
1. Anything that tests that `SimulateNative` throws. This is a property
that native event dispatching doesn’t have so I can’t convert that
easily. Affected test suites: `EventPluginHub-test`,
`ReactBrowserEventEmitter-test`.
2. Anything that tests `ReactTestUtils` directly. Affected test suites:
`ReactBrowserEventEmitter-test` (this file has one test that reads
"should have mouse enter simulated by test utils"),
`ReactTestUtils-test`.
3. Anything that dispatches a `change` event. The reason here goes a bit
deeper and is rooted in the way we shim onChange. Usually when using
native event dispatching, you would set the node’s `.value` and then
dispatch the event. However inside [`inputValueTracking.js`][] we
install a setter on the node’s `.value` that will ignore the next
`change` event (I found [this][near-perfect-oninput-shim] article
from Sophie that explains that this is to avoid onChange when
updating the value via JavaScript).
All remaining usages of `Simulate` or `SimulateNative` can be avoided
by mounting the containers inside the `document` and dispatching native
events.
Here some remarks:
1. I’m using `Element#click()` instead of `dispatchEvent`. In the jsdom
changelog I read that `click()` now properly sets the correct values
(you can also verify it does the same thing by looking at the
[source][jsdom-source]).
2. I had to update jsdom in order to get `TouchEvent` constructors
working (and while doing so also updated jest). There was one
unexpected surprise: `ReactScheduler-test` was relying on not having
`window.performance` available. I’ve recreated the previous
environment by deleting this property from the global object.
3. I was a bit confused that `ReactTestUtils.renderIntoDocument()` does
not render into the document 🤷

* Make sure contains are unlinked from the document even if the test fails
* Remove unnecessary findDOMNode calls
* Generate Flow config on install
We'll need to do pre-renderer Flow passes with different configs.
This is the first step to get it working. We only want the original version checked in.
* Create multiple Flow configs from a template
* Run Flow per renderer
* Lint
* Revert the environment consolidation
I thought this would be a bit cleaner at first because we now have non-environment files in this directory.
But Sebastian is changing these files at the same time so I want to avoid conflicts and keep the PR more tightly scoped. Undo.

```
* Installed 3.x release of react-lifecycles-compat
* Updated ReactComponentLifeCycle-test and ReactDOMServerLifecycles-test to cover both polyfilled lifecycles in StrictMode
* Updated StrictMode warnings to not warn about polyfilled getSnapshotBeforeUpdate
* New context API
Introduces a declarative context API that propagates updates even when
shouldComponentUpdate returns false.
* Fuzz tester for context
* Use ReactElement for provider and consumer children
* Unify more branches in createFiberFromElement
* Compare context values using Object.is
Same semantics as PureComponent/shallowEqual.
* Add support for Provider and Consumer to server-side renderer
* Store providers on global stack
Rather than using a linked list stored on the context type. The global
stack can be reset in case of an interruption or error, whereas with the
linked list implementation, you'd need to keep track of every
context type.
* Put new context API behind a feature flag
We'll enable this in www only for now.
* Store nearest provider on context object
* Handle reentrancy in server renderer
Context stack should be per server renderer instance.
* Bailout of consumer updates using bitmask
The context type defines an optional function that compares two context
values, returning a bitfield. A consumer may specify the bits it needs
for rendering. If a provider's context changes, and the consumer's bits
do not intersect with the changed bits, we can skip the consumer.
This is similar to how selectors are used in Redux but fast enough to do
while scanning the tree. The only user code involved is the function
that computes the changed bits. But that's only called once per provider
update, not for every consumer.
* Store current value and changed bits on context object
There are fewer providers than consumers, so better to do this work
at the provider.
* Use maximum of 31 bits for bitmask
This is the largest integer size in V8 on 32-bit systems. Warn in
development if too large a number is used.
* ProviderComponent -> ContextProvider, ConsumerComponent -> ContextConsumer
* Inline Object.is
* Warn if multiple renderers concurrently render the same context provider
Let's see if we can get away with not supporting this for now. If it
turns out that it's needed, we can fall back to backtracking the
fiber return path.
* Nits that came up during review
