* Simplify applying layout transition in preparation for bigger layout transition API work * Change from apply to complete in if layout transitions are involved and _applyLayout: to _setCalculatedLayout: for layout * Change to applySubnodeInsertions and applySubnodeRemovals * Change from completeTransition to commitTransition and flip logic around when to trampoline to the main thread for implicit hierarchy management * More internal API improvements * Fix merge conflicts * Rename _layout to _calculatedLayout
