Summary: For our -objc efforts we'll be excluding vendorlibs from these changes for now and then working on getting them to not have to be fully linked as a second effort. The way -objc flag works is its an all or nothing flag for the app and thus for any library we still want to link completely we'll have to add a link_whole = True to the BUCK file. (Otherwise we'll have crashes in these libraries :P).

Summary: YGRoundValueToPixelGrid does not handle float point values correctly. It causes layout bugs in arm 32 devices. The way values are rounded to pixel grid is the following: if value is close to the left pixel - discard error and set it equal to left pixel. If value is close to right pixel - set it equal to the right pixel. Otherwise if value is closer to the left - set it equal to the left, closer to the right - set it equal to the right. The problem is when values are close to the middle. Old implementation could produce either left or right boundaries. This patch moves all values that are close to the middle to right boundary. This way results are consistent.

Summary:
More fine grained dirty marking
Currently a node's dirty flag propagates to the root of the tree ensuring that when any node is invalidated its whole subtree will be re-calculated. This is often times not needed. There are many properties which only effects a node's children and would not need to propagate all the way to the root such as align-items. Also in cases where the style does change layout it may not need to propagate all the way to the root but can often stop at the nearest position: absolute parent.
This change has the potential of greatly improving performance of re-calculating a tree.
This might require adding a second dirty flag named hasDirtyDescendants ensuring that traversal still works even though a parent is not marked as dirty.

Summary:
Source-only ABIs are a new feature of Buck that allows massive parallelism
by generating ABI jars from just the source code (without looking at most

makes assumptions about how we write Java code. This commit updates
Instagram's code to conform to those assumptions.

Summary:
This is meant to show a possible route format for a persistent form of Yoga. Where previous layouts can remain intact while still taking advantage of incremental layout by reusing previous subtrees.
```c
YGNodeRef YGNodeClone(const YGNodeRef node);
```
The core of this functionality is a new API to clone an existing node. This makes a new detached node with all the same values as the previous one. Conceptually this makes the original node "frozen" from that point on. It's now immutable. (This is not yet enforced at runtime in this PR but something we should add.)
Since the original is frozen, we reuse the children set from the original node. Their parent pointers still point back to the original tree though.
The cloned node is still mutable. It can have its styles updated, and nodes can be inserted or deleted. If an insertion/deletion happens on a cloned node whose children were reused, it'll first shallow clone its children automatically.
As a convenience I also added an API to clear all children:
```c
void YGNodeRemoveAllChildren(const YGNodeRef node);
```
During insert/delete, or as a result of layout a set of reused children may need to be first cloned. A kind of copy-on-write. When that happens, the host may want to respond. E.g. by updating the `context` such as by cloning any wrapper objects and attaching them to the new node.
```c
typedef void (*YGNodeClonedFunc)(YGNodeRef oldNode,
YGNodeRef newNode,
YGNodeRef parent,
int childIndex);
void YGConfigSetNodeClonedFunc(YGConfigRef config,
YGNodeClonedFunc callback);
```
This PR doesn't change any existing semantics for trees that are not first cloned.
It's possible for a single node to exist in two trees at once and be used by multiple threads. Therefore it's not safe to recursively free a whole tree when you use persistence. To solve this, any user of the library has to manually manage ref counting or tracing GC. E.g. by replicating the tree structure in a wrapper.
In a follow up we could consider moving ref counting into Yoga.

Summary:
@public
== Before ==
- Aspect ratio would do its best to fit within it's parent constraints
- Aspect ratio would prioritize `alignItems: stretch` over other sizing properties.
== After ==
- Aspect ratio is allowed to make a node grow past its parent constraints. This matches many other aspects of flexbox where parent constraints are not treated as hard constraints but rather as suggestions.
- Aspect ratio only takes `alignItems: stretch` into account if no other size definition is defined. This matches the interaction of other properties with `alignItems: stretch`.
== Updating your code ==
**You probably don't need to do anything** but in case something does break in your product it should be as easy as adding `{width: '100%', height: '100%', flexShrink: 1}` to the style declaring the `aspectRatio`.

Summary:
Currently the nbind asm.js output generates boilerplate code which can conditionally load node's `fs` and `path` modules. If this output is run directly in the browser there are no issues but if you run it through a bundler the build step will fail trying to resolve the node builtins.
Workarounds currently exist for bundlers like webpack (mentioned in #444) but this is not a safe assumption to make (for example such workarounds don't exist for `metro-bundler`).
I am by no means suggesting that this is the perfect solution but this might provide a stop-gap fix for people who are currently blocked by this issue (like I am).

- [no-wrap] total flex basis of all child nodes is greater than available space in parent and there are no flexible children
- [no-wrap] after flexing there is still not enough space to layout all child nodes

If that result is not zero, divide it by (if the result was positive) its **flex grow factor floored at 1** or (if the result was negative) by its scaled flex shrink factor, having **floored the flex shrink factor at 1**. This is the item’s max-content flex fraction.
But at least it seems a required change.
