Move component recursion to ReactReconciler

[mridgway]

See facebook/react@master...mridgway:reconcilerRecursion for progress.

This PR involves removing ReactReconciler calls and still maintain event queue orders for React*Component. From my analysis these are the spots that need to be addressed:

ReactCompositeComponent

mountComponent

Mount queue: componentDidMount (post-recursion)

• hoist ReactReconciler calls
• Add postMount interface to handle post-recursion

receiveComponent

Mount queue: componentDidUpdate (post-recursion)

• hoist ReactReconciler calls
• Add postUpdate interface to handle post-recursion

unmountComponent

• hoist ReactReconciler calls

ReactDOMComponent

mountComponent

Mount queue: trapBubbledEventsLocal (pre-recursion), putListener (pre-recursion), focusDOMComponent (post-recursion)

• hoist ReactReconciler calls
• Add postMount interface to handle post-recursion

receiveComponent

Mount queue: putListener (pre-recursion), postUpdateSelectWrapper (post-recursion)

• hoist ReactReconciler calls
• Add postUpdate interface to handle post-recursion

unmountComponent

• hoist ReactReconciler calls

ReactReconciler

Also, ReactDOMComponent uses DomLazyTree objects that the reconciler would need to recognize. In order to keep ReactReconciler decoupled, there will need to be a generic interface for trees and a plugin for handling DomLazyTree specifically.

mountComponent

• implement recursion
• attachRefs queue (pre: must be before other queued methods)
• implement generic LazyTree injection
• call postMount on React*Component for implementing post-recursion event queueing

receiveComponent

• implement recursion
• call postUpdate on React*Component for implementing post-recursion event queueing

unmountComponent

• implement recursion
• call postUnmount for implementing post-recursion event removal

Testing

• Fix tests that are affected by internal API changes
