The approach is quite simple: we check the thread id, and if it matches the caller thread id, we unlock mutexes which lead to the normal uninterrupted execution flow.

Summary:
This diff implements iOS-specific `PlatformRunLoopObserver` (and `MainRunLoopObserver`) that then being glued together with `SynchronousEventBeat` replaces `MainRunLoopEventBeat`, and then same thing glued with `AsynchronousEventBeat` replaces `RuntimeEventBeat`.
So, instead of two platform-specific classes we had on iOS (for that needs), now we have only one (that can be reused for a more broad variety of applications).

Summary:
We use `EventBeat::OwnerBox` in the `EventBeat` infra to represent weak ownership of classes that contain that, so those classes can ensure own life-time at some critical points.
Before this diff, we stored a pointer to EventDispatcher right after we create it. However, some components that we build require to have a valid pointer from the beginning (even before the EventDispatcher is created). To satisfy this requirement, we create a dummy pointer first and use it as an owner, then we merge (share control block) the pointer to an EventDispatcher into that. It works because the owner pointer never gets dereferenced (it's `void *`), so it does not matter which object it represents while it represents correct ownership.
In the future, this approach will allow us to remove the concept of `OwnerBox` completely and use just `std::weak_ptr<void>` instead.

Summary:
We consume Hermes through multiple .so's, which means we have multiple (weak) typeinfo definitions of facebook::jsi::JSError. Previously we were using gnustl, which would strcmp typeinfo to decide whether a certain exception handler applies, which meant this didn't cause any major issues. However since this is deprecated, we recently switched to libc++, which does not have this by behaviour (or it does, but behind a flag I'm not sure how to enable). This causes any JS exceptions to fall through from our exception handlers and fatal the app.
This problem is actually documented in the common Android NDK problems page: https://android.googlesource.com/platform/ndk/+/master/docs/user/common_problems.md#rtti_exceptions-not-working-across-library-boundaries
The suggested solution is to ensure that any exception types have a key function defined (a non-pure, out-of-line virtual function). The simplest one to add is a virtual destructor. This makes the object file that holds the implementation of the destructor export a non-weak typeinfo definition which will at load time override the other weak versions.
I'm not sure why we're the first to hit this. RN's JSIExecutor doesn't explicitly reference JSError which probably helps (https://github.com/facebook/react-native/blob/master/ReactCommon/jsiexecutor/jsireact/JSIExecutor.cpp#L256-L258) and they also don't use unguarded callbacks like we do.

`RunLoopObserver` is one of the core interfaces that bridge intrinsically platform-specific functionality to cross-platform React Native core. `RunLoopObserver` allows subscribing for notifications about changes in a run loop life cycle. Primarily it supposed to be used for observing UI (aka main) and JavaScript execution thread/run-loop.
Having a `RunLoopObserver` implemented in a platform-specific manner allows building these components in a cross-platform manner:
* Sync and async UI event delivery pipeline;
* Timing for some animation engine;
* Timers (probably additional features are required).

Summary:
The core issue solved in D21389371 was that erased elements of a TinyMap were being iterated over, because TinyMap has somewhat-complicated logic around cleaning out the underlying vector. In some very marginal cases, vectors were not being cleaned and an iterator pointing at erased elements was being returned.
The diff prevents some possible crashes in `begin()` and `find()` while making it much less likely to iterate over erased elements.
We also add a unit test to catch the case fixed in D21389371, in particular.
We also are keeping the code added in D21389371 (for now) since it's a cheap check, and will be a safeguard until we have rigorous testing around TinyMap. To be clear that logic should noop currently, but will prevent crashes in case guarantees around TinyMap change in the future.
Currently there is only one line of code that actually uses the TinyMap iterator, so this should be safe.

Summary:
When we call `.erase` on the TinyMap, it sets the key of the element to 0. When we call `.begin()` later, TinyMap will sometimes, but not always, clean up the underlying Vector. This means that *most* of the time, underlying erased elements will be removed from the Vector; but sometimes erased elements will still be there when iterating over it.
This was causing us to generate extra "Create" mutations.
To fix this, for now we just check for zeroed-out elements when iterating over the vector.

Summary:
I spent the last several days thinking about state reconciliation issues, some crashes (T65586949) that suspiciously happen somewhere inside, and a bunch of issues that might be connected to that (possibly, some of T65516263 sub-task).
I cannot see some obvious problems in the current state reconciliation algorithm that might cause the crash (because of some use-after-free or other pure C++ issues), but I suspect some of the problems we experience might be caused by some details of how we reconcile states.
In the current approach, we rank all states based on the "hierarchical" history of their creation (state version is being calculated based on the version of the base tree). That's usually fine but in some cases when trees are being constructed concurrently, a logical version of a based tree does not correspond to the local version of a committed tree. In other words, the linear history of commits does not always correspond to the "hierarchical" history of trees generation that was done by different parties (e.g. React vs native state update pipeline).
In this diff, I tried to change the approach to change the algorithm to follow this logic: If some state is `obsolete` (already been committed and then replaced with newer one), we replace that with the most recent one. This change does not introduce the `obsolete` flag; is already used by State infra to avoid cloning nodes with an outdated state.
Interestingly, it fixes the issue with an empty BottomSheet on Android (T66177144). See the attached video. The hope is that it's also will
This change theoretically might affect all things that use State, so it hard to predict what can break and how. So, if we don't see obvious problems here, I would set up a GK/QE and run the experiment in prod.
