* Commentary
Revert "Ensure ASControlMode properties lock before accessing their ivars (#1476)"
This reverts commit ce1e1956f4.
Revert "Make sure all ASDisplayNode properties have backing ivars for consistency. (#1475)"
This reverts commit d6061f4390.
- Except the unused property `interfaceStateSuspended` is still removed (this is a memory saver).
* Shrink ASImageNode by .6% and ASNetworkImageNode by 2.2%
ASImageNode goes from 1384 to 1376. ASNetworkImageNode goes from 1496 to 1464.
These objects accumulate in the heap, so reducing their size will allow more to accumulate before memory warnings.
Group the `BOOL`s into a struct. Shrink the various stored `enum`s to fit the size of their contents. Move the ivars around so that the smaller `enum` are near eachother and the bitfield struct.
* add comments as requested in garrett's review.
* access ivar directly since already locked as suggested in review.
* Shrink ASDisplayNode from 1088 to 976 bytes, reduction of 11.48%

* Forgot to bit-field-ify placeholderEnable; new small size is 968, old size is 1072 (measured consistentlyl on iPhoneSE simulator). 10.74% reduction.
* Shrink _ASPendingState from 824 to 808 bytes, reduction of ~2%
These objects accumulate in the heap, so reducing their size will allow more to accumulate before memory warnings.
Shrink ASPendingState BOOLs. Use unsigned int for these bitfields for clarity. Separate from `_flags` as that struct is compared to `0` for testing. The `_boolFlags` struct is just storing other `BOOL`s.
* rename struct fields as suggested in garret's review.
* Make sure all ASDisplayNodes have backing ivars for consistency.
Found this by enabling #pragma clang diagnostic error "-Wobjc-missing-property-synthesis" for ASDisplayNode. One property is unused, saving 8 bytes of heap space per instance on 64-bit builds. Implement setter/getters for these properties, and add appropriate locking. add the warning as error to the build for this file.
* Remove ASEventLog. We'll focus on ASLog for the future, possibly making it triggerable on a per-node basis

* Rename ASDN C++ namespace to "AS." Referring to the framework as ASDisplayNode is pretty out-dated and verbose. See CoreAnimation which usees CA for their internal namespace.
More using
* More cases
Right now when an image node enters preload state, we kick off an image request with the default priority. Then when it enters display state, we change the priority to "imminent" which is mapped to the default priority as well. This means that requests from preload and display nodes have the same priority and are put to the same pool. The right behavior would be that preload requests should have a lower priority from the beginning.
Another problem is that, due to the execution order of -didEnter(Preload|Display|Visible)State calls, a node may kick off a low priority request when it enters preload state even though it knows that it's also visible. By the time -didEnterVisibleState is called, the low priority request may have already been consumed and the download/data task won't pick up the new higher priority, or some work needs to be done to move it to another queue. A better behavior would be to always use the current interface state to determine the priority. This means that visible nodes will kick off high priority requests as soon as -didEnterPreloadState is called.
The last (and smaller) issue is that a node marks its request as preload/low priority as soon as it exits visible state. I'd argue that this is too agressive. It may be reasonble for nodes in the trailing direction. Even so, we already handle this case by (almost always) have smaller trailing buffers. So this diff makes sure that nodes that exited visible state will have imminent/default priority if they remain in the display range.
All of these new behaviors are wrapped in an experiment and will be tested carefully before being rolled out.
* Add imports
* Fix build failure
* Encapsulate common logics into methods
* Address comments
* Optimize ASTwoDimensionalArrayUtils
These methods are called on the main thread during range controller updates (i.e. every frame) and so they should be as fast as possible.
* Rename
* Use vector instead of stack array to handle really big cases (e.g. photos)
* Add an experimental flag to use native dispatch_apply instead of our core count * 2 approach. This has shown performance wins in some profiling.
* Add in other places
* Improve separation of code for layout method types
* Address PR comments
- Delegate to layout spec engine if the node is a layout spec node but yoga engine was asked for calculate the layout
- Change ASLayoutType to ASLayoutEngineType
- Improve layout engine fall through code
Initializing the LUT arrays at file level scope creates a large chunk of code retaining and releasing all of the NSStrings in the tables. Moving them to function level moves the initialization to being lazy.
* Introduce ASCellLayoutMode
* Some smaller improvements
* Improve logic around _superPerformBatchUpdates:completion:
* Add comment about default values for ASCellLayoutModeNone
