Summary:
Currently, we can dirty leaf nodes with `measure` function, we also can get `dirty` status for any node, but we cannot handle a moment when this change happen. This diff introduces a new call-back-manner handler for it.
We need this to plug Yoga inside and outside other layout systems without maintaining own dirty propagation infrastructure.
Consider using Yoga for flex-box layout in React Native where we can have deeply nested layout like `<View><Text><View><Text/></View></Text></View>` where all content of all <Text> nodes are laid out using native text/inline (not flex-box!) layout system. In this case, when some change dirties some deeply nested Yoga node, we have to propagate the dirty state down to outer one. Having this handler makes possible to wire up `on-dirty` handler on the root node and `setDirtied` for the leaf node.
Removing custom dirting mechanism from React Native should drastically simplify rendering layer and bring a huge performance win.

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:
**Breaking Change Notes**
To adapt to the breaking change, app developers that are consuming React Native through CocoaPods must update their Podfile to refer to yoga with a lowercase "y". In other words:
pod 'Yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
Must be changed to (note the lowercase "y"):
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
**Symptom**
If you consume React Native as a CocoaPod and consume a third-party React Native module not as a CocoaPod, you will receive a `nonportable-include-path` warning in Xcode >= 8.3.
**Details**
Xcode 8.3 introduced -Wnonportable-include-path which triggers if you import a header using different casing than the path to the header on disk. This triggers when consuming React Native as a CocoaPod from a library that isn't a CocoaPod. React Native imports Yoga using paths like this:
#import <yoga/Yoga.h>
Which means Yoga's headers are expected to be located in a directory called "yoga" with a lowercase "y". However, when React Native is a CocoaPod the Yoga headers for non-CocoaPods end up in the directory "$(BUILT_PRODUCTS_DIR)/Yoga".
To fix this such that Yoga's headers end up in "$(BUILT_PRODUCTS_DIR)/yoga" (note the lowercase "y"), I've changed Yoga's podspec name to have a lowercase "y".
**Test Plan**
Created a test app where React Native is consumed as a CocoaPod. Added the react-native-maps library to the project and configured it to not be consumed through CocoaPods. Verified that the app compiles properly without the `nonportable-include-path` warnings.

Summary:
== 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:
The only thing I found in the spec for this change is the following. Not exactly sure if this is the thing this PR is about:
> For each flex item, subtract its outer flex base size from its max-content contribution size. 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.
