eabf29e320 Fabric: Getting rid of many auto &&
Summary:
@public
After reading about move-semantic and rvalue refs I realized that we (I) definitely overuse  `auto &&` (aka universal reference) construction. Even if this is harmless, does not look good and idiomatic.
Whenever I used that from a semantical point of view I always meant  "I need an alias for this" which is actually "read-only reference" which is `const auto &`.
This is also fit good to our policy where "everything is const (immutable) by default".
Hence I change that to how it should be.

20a8673b48 iOS: create EventTarget when creating EventEmitter and keep it until the emitter is deallocated.
Summary:
@public
There are some race conditions between VM objects getting deallocated and the instanceHandle held by the eventEmitter can point to deallocated memory space, causing undefined behavior like a crash.
For now, keep a strong ref to the eventTarget inside EventEmitter to avoid that scenario. This is a temporary workaround.

2ca4770011 fabric: send events via JS thread
Summary: Calling the event emitters on the main thread seems to be problematic, so let's dispatch it via the JS thread. This requires some changes to make "eventTarget" single-use because otherwise the binding would need to synchronize the actual JS call with the act of releasing the target.

d49ebbcf62 Fabric: All *EventHandlers were renamed to *EventEmitter
Summary:
Using `EventHandlers` name was a bad idea, and I cannot tolerate it anymore.
The worst part of it is that when you have a collection of `EventHandlers` objects you cannot use plural word to describe it because `EventHandlers` is an already plural word.

And, this object is actually an event emitter, the thing on which we call events.
