Every use case involving some sort of key set on a component would give birth to a leak in an async context:
- If a key of a component changed, the outdated one was never destroyed.
- destroyed component were never removed from their parent's reference map.
This commit solves both issues, that are tightly linked anyway.
Have a component which does a render in its onWillPatch, onPatched, onMounted hooks.
Before this commit, the result was incorrect: the second rendering was not taken into account.
After this commit, those renderings are correctly applied at the price of a delayed render when the fiber
is in a critical state.
Have a child component on which a render is triggered.
This component delays its willUpdateProps and makes a rendering during the willUpdateProps
Before this commit, renderings of the child were inconsistent across
its parent's renderings.
After this commit, it works as expected.
When a parent and a child were rendered at the same time, it was
possible for the 2 renders to decrement the same fiber internal
counter, which meant that the render was stalled.
Aim to replace the abstraction "Context" from OWL 1 with the new primitives
"atom" and "useState":
- notification is done only after a batch of modifications.
- observers are notified at most once for a batch.
- an observer of type component is notified (and rerendered)
only if it does not have an ancestor that has to be notified for the
same batch of operations (anywhere in the web of references!).
- notification of components is done on all levels "simultaneously".

The point is to have visibility on the development of the owl2 features.
This commit reintroduces some tests keeping them skipped in order to fulfill that purpose.
There still are some missing tests though.
