* Use childrenMap directly to prevent creating an NSArray in ASDK for ASLayoutSpec children
* Add locking for parent property in ASLayoutSpec
* Remove unnecessary import
* Add newline
* Add NSFastEnumeration to ASEnvironment and ASDisplayNode / ASLayoutSpec
* Change NSMutableArray initializer to arrayWithCapacity:
* Move ASLayoutSpec+Private.h into Private folder
Fixes building with Swift
* Remove lock for ASLayoutSpec parent
* 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
* Fix ASTextNode's ascender to also include the line height specified by paragraph style in the attributed string.
* Merge conflict (original patch is for an old version)
* [ASEnvironmentTraitCollection] default user interface idiom to ASEnvironmentTraitCollection
UIUserInterfaceIdiomUnspecified is -1 so we were actually defaulting our trait collection to UIUserInterfaceIdiomPhone (which is 0).
* Fix a few places where we weren’t using the default method to create the base traits

[ASDataController] Put other stuff back
[_ASHierarchyChangeSet] Use fast enumeration
[_ASHierarchyChangeSet] Fix assertion format strings, return on fail so we don't crash in production
[ASDataController] Store data source item counts as vector rather than NSArray
[ASDataController] Build some tests for the update validation

Apple claims in the AVFoundationProgramming Guide that HLS videos can be constructed only through URL, but later with iOS 4.3 release notes it claimed to bring updates to how the HLS videos should be initialized, which works with asset too. I’ve tested with both, and it looks like initializing with asset is buggy.
* [ASDisplayNode+AsyncDisplay.mm] Refactor display block creation method for conciseness and readability.
* [ASDisplayNode+AsyncDisplay.mm] Some additional fixes / improvements that are required for the prior commit.
* Fix one last spot of the merge with __instanceLock__.unlock();
* [ASDisplayNode] Short circuit measure calls that have a zero-area constrainedSize.
// If the constrainedSize is completely zero-area, then there is no possibility for layout calculations to be successful.
// This also avoids the issue of an inset being applied to 0, creating negative frame values.
* [ASDisplayNode] Fix to shouldMeasure change.
* One more fix.
