* [ASDisplayNode] Add safeAreaInsets, layoutMargins and related properties to ASDisplayNode * Add layoutMargins bridged to the underlying view * Add safeAreaInsets bridged to the underlying view * Add fallback calculation of safeAreaInsets for old iOS versions * Add automaticallyRelayoutOnSafeAreaChanges and automaticallyRelayoutOnLayoutMarginsChanges properties * Add additionalSafeAreaInsets property to ASViewController for compatibility with old iOS versions * Provide safeAreaInsets for layer-backed nodes. This also fixes tests. * Fix crash when insetsLayoutMarginsFromSafeArea is set from a background thread * Changes requested at code review: * Update documentation for layoutMargins and safeAreaInsets properties. Suggest that users set the automaticallyRelayout* flags to ensure that their layout is synchronized to the margin's values. * Fix accessing ASDisplayNode internal structures without a lock. * Add shortcut in -[ASDisplayNode _fallbackUpdateSafeAreaOnChildren] to skip a child when possible. * Add shortcut in ASViewController to avoid fallback safe area insets recalculation in iOS 11. Fix fallback safe area insets recalculation when the additionalSafeAreaInsets are set. * Add debug check that a view controller's node is never reused without its view controller, so the viewControllerRoot flag value is always consistent. * Use getters instead of reading ivars directly in -layoutMarginsDidChange and -safeAreaInsetsDidChange. * Minor change in CHANGELOG * Minor change in ASDisplayNodeTests.mm
