Summary: Quite obvious. We have to check `sealable` flag of the child (not a parent) before mutating it.

Summary:
We have to call shallowSourceNode() in all cases of cloning which were not caused by UIManager instructions,
otherwise the diffing alogorith might produce incorrect mutation instructions.

Summary:
The method replaces the current source node with its source node.
It's useful when we have to clone some node but don't want to change a source node pointer.

Summary: Previously we recreate a vector with pointers to child nodes every single time we modify the collection. That was okay but recently I realized that the we can simply make a copy of the vector one time during object construction and then mutate it freely.

Summary: Slightly new approach: Some non-const methods might not always mutate objects, so sometimes we should call `ensureUnsealed()` only inside conditional branches where we actually mutate an instance.

Summary:
First, LayoutableShadowNode::cloneAndReplaceChild() is now pure virtual. The default implementation was useless and confusing.
Second, cloneAndReplaceChild() is now fully implemented for ViewShadowNode, so fancy Yoga Concurrent layout *should* work now.

Summary:
We use shource nodes only in the diffing alogorithm. It implies that we have strong pointers to those nodes in trees we compare against.
Using weak_ptr's allows to avoid memory leaks.
