Valentin Shergin 88b8616437 Fabric: Using `unordered_map` instead of `map` for RawProps
Summary:
@public
We don't need to maintain an order of this collection, so using `unordered_map` is more appropriate.

Valentin Shergin e906d4cdc9 Simplifying child nodes management in YogaLayoutableShadowNode
Summary:
@public

This diff consists of many interdependent changes which support one simple idea: YogaLayoutableShadowNode is now using YGNode children to iterate on them (it previously relied on `ShadowNode::getChildren()`). All other changes are just an unavoidable consequence of that. Hence we don't need to filter child nodes every single time when we do layout anymore! The logic around `clone callback` is also drastically simpler now.
The new approach also implies that `LayoutableShadowNode` and `YogaLayoutableShadowNode` don't use `shared_ptr`s to refer to ShadowNode objects because new relationship does not imply ownership. No more `SharedShadowNode` objects in those two classes.

Summary:
@public
On Android, a color can be represented as 32 bits integer, so there is no need to instantiate complex color objects and then pass them as shared pointers.  Hense instead of using shared_ptr, we use a simple wrapper class which provides a pointer-like interface.

Valentin Shergin fcd72bf34a Fabric: Generalizing cloning of YogaLayoutable approach
Summary:
@public
Non-null owner pointer in Yoga node indicates that this node is already being used by some other subtree, so it must be cloned in case of possible (re)layout.
Theoretically, this node must/can be cloned by Yoga right before applying a new layout to this node, but Yoga has a special optimization that uses that fact that Yoga always cloning *all* children of a particular node altogether. This is not true for React; to meet React and Yoga worlds we double check the owner pointer in `addChild` and clone node preliminary if needed.

Valentin Shergin e8ec1cb16a Fabric: The diffing algorithm does not use source nodes anymore
Summary:
@public
... and it's as efficient as it was before.

The previous version of the algorithm used `sourceNode` reference to know the previous state of the node to call the algorithm recursively.
That wasn't so good because of several reasons:
 - It was fragile because we had two different sources of the truth of the "previous state of the tree": committed tree and source node pointer;
 - We had to store weak pointers to source nodes inside cloned nodes. That is not free in terms of performance;
 - The old approach introduced a constraint that all previously used and now reinserted nodes must be cloned to update source node (otherwise, the algorithm would regenerate instructions recreating already existing subtrees);
 - That cloning required access to `isSealed` flag which is supposed to be a debug-only thing (that actually affects performance and must be compile-out for release builds).

The new approach compares nodes with same react tag and naturally cloning-artifacts resilient.

Yes, the new approach uses a map of inserted nodes, but the previous one already had it (otherwise there is no way to tell which nodes should be "deleted"). And anyway, this is a very little map that exists for a very little period of time.

Summary:
@public
This is follow up for D8601600 and D8247652 (the last one has detailed explanation of the problem).
From this commit I propose that we have to follow simple rule:
If some prop has a default value which differs from the default value of its type, we have to specify it as {<value>} in .h file and explicitly in .m file, for all other props the default value must not be specified explicitly (in .h files it must be specified as {}).
The reason is that we have to embrase those cases and establish behaviour: if we change the default value in .h file, it always means that we have to change the value in .cpp file too.

At this point, we are not sure should it be this way or not. But we are sure that for some extremely noisy events (like onLayout) we have to make an exception right now (otherwise overall performance will suffer).
So, this diff implements that for `onLayout`.

Valentin Shergin 8ef539e0c2 Fabric: `fromDynamic`: Parsing vector type when source has no array
Summary:
@public
If some prop has `std::vector` type, it possible that on JS side we want to pass just one element of the array.
And in this case we sometimes drop array initialization (`[]`) part, so instead of passing `[{x:1, y:1}]` we pass `{x:1, y:1}`.
This diff adds support for that.

Valentin Shergin 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.

Valentin Shergin 0a20f47021 Fabric: Proxying `pointScaleFactor` to Yoga Config
Summary:
@public
This diff changes how we store and manage Yoga Config in layoutable shadow nodes.
Previously we have `shared_ptr` to single shared yoga config (one to many relationships); now we initiate and store yoga config with yoga node (one to one relationship).
Cons:
 - Less memory efficient.
Pros:
 - Much more flexible model. Configuration can be tweaked on a per-node basis.
 - More performant. Dealing with `shared_ptr` is expensive because of atomic ref-counter. (This is not really applicable for the previous approach but would be applicable for any alternate approach where we want to have more granular control of the configuration.) Data locality is also great in the new model which should positively impact performance.
 - Simplicity. Any alternate approach where we manage sets of nodes which share the same configuration is going to be quite complex.

Valentin Shergin 7f1ed6848f Fabric: `convertRawProp` was extended to accept an optional default value
Summary:
During transforming raw prop (`rawProps[<prop>]`) to typed props (`MyProps.<prop>`) we can face three different cases:
 * `rawProps` collection has proper serialized value for the key. In this case, we have to set a new value of the typed prop converting value using `fromDynamic`.
 * `rawProps` collection does not have value for the key. In this case, we have to copy a value from source prop (`sourceValue`).
 * `rawProps` collection has `null` value for the key. This is the special case which means that the prop was removed from the particular component instance and we have to reset it to some *default* value (which is *not* the same as `sourceValue`). Now the default value of the `defaultValue` (sic!) argument is a default value of the type of the value (which may be different from logical default value).

We didn't handle the last case previously and this caused crashes (and unexpected behavior) because `fromDynamic` often cannot handle `null` value.

And yes, all this mean that we also have to update all `convertRawProp` call sites where logical default values are not equal to type-specific default values. This is a potential error-prone place, especially because now we have to specify logical default values in two places (in a prop declaration and in a parameterized constructor). And seems there is no way to avoid that without performance loss (because both of those places are basically constructors).

My hope is that codegen (where default values are also defined in JavaScript) will help with it eventually.

Valentin Shergin 957ef606b9 Adding `Wrapper` suffix to `EventHandler` and `EventHandler` type names
Summary:
It's maybe not so important/crucial, but this thing bothers me a lot.
We use raw opaque `EventTarget`, `InstanceHandle` and `EventHandler` pointers in application layer quite a lot and we don't have any kind of type-safety here. I believe all those opaque types should be represented as named scalar types which compiler at least can differentiate at compile time.
So I propose introducing named aliases for them which will point to particular empty `struct`s. This will allow us to tag types properly in all functions and methods and ensure that we pass right values as right arguments.
Again, they are *just aliases*, which are effectively still `void *`, no any additional logic or names are involved.

Unfortunately, those nice type names are already taken by `JSIFabricUIManager` local anonymous namespace (even if they are inside anonymous namespace we cannot use them https://stackoverflow.com/questions/3673353/anonymous-namespace-ambiguity).  I think it's fair to rename them because... it's local. And we already use `Wrapper` suffix for them anyways.

Valentin Shergin 2a3025da97 Fabric: Application layer of events infrastructure
Summary: This implements `EventHandlers` abstract class (aka "Events Guy") which encapsulates `eventDispatcher` and `instanceHandle` (and ownership of future `eventTarget`), all of this as part of existing {ShadowNode + Props + LayoutMetrics + LocalData + Descriptor + (and now) EventHandlers} infra. (We don't plan to add anything else to this model. Ever.)

Valentin Shergin d94a9e2640 Fabric: Composing YGNode object inside ShadowNode to avoid memory allocation overhead
Summary:
Given that fact that life-time of YGNode and ShadowNode objects must be idential and that we always allocate ShadowNode on heap,
we can embed YGNode object right inside ShadowNode object and use pointer to it safely.
That allows us to save additional memory allocation for every single layoutable shadow node! Whoo-hoo!
