Although it is unreasonable to set every possible property for
simulated events, `type` is useful for event handlers that are shared
between types and potentially have different behaviors.

(cherry picked from commit 510155e027)
For clarity.
I left "native event" as-is because there's a lot of it, it's not particularly ambiguous, and SimulateNative/nativeTouchData are public API in ReactTestUtils.
(cherry picked from commit ba9b985406)
This makes it easier to figure out where the docs live.
Googling for e.g. `react-addons-update` also works, but this should
make things easier for people that hyperclick directly to the source.
(cherry picked from commit db175052c0)
This is a little simpler (and a teeny tiny bit faster). The one in ReactCompositeComponent stays because of the way we create ReactCompositeComponentWrapper inside instantiateReactComponent.
We were shallow-rendering a component that used refs at FB so this can't go in as-is. It's a little unclear what we _should_ do though, since there is nothing to hold a ref to (since we're shallowly rendering) and we generally promise that child refs are resolved before a parent's componentDidMount. Also, changing shallow rendering to use the original `_renderValidatedComponent` (instead of `_renderValidatedComponentWithoutOwnerOrContext`) breaks tests because now the `_owner` field doesn't match up for `toEqual` (non-null in `getRenderOutput` but null if constructed in a test).
My last strategy of getting each node recursively while unmounting was a pain to make work properly with ReactMount's confusing cache. Now, we get the node before unmounting anything in the subtree (and we don't try to find the nodes of descendants).
This is a temporary solution and can go away when we get rid of the giant ReactMount node hash map.
Fixes#5151.
Now we don't repurpose context for our own secret needs (hi Dan). In this diff I avoid storing the native parent on native (DOM) components and store it only on composites, but we'll probably want to store it on native components too soon for event bubbling.
When calling ReactTestUtils.Simulate, sometimes you want to test that an exception is thrown by the event handler. This lets you do that without relying on the fact that old jsdom doesn't implement `Event`.
Behind a feature flag. This is a relatively simple change; adopting this strategy universally would mean that we could clean up a lot of code but this doesn't attempt to restructure more than necessary.
