This is used in a stack where I'm using YogaKit on tvOS. fb_apple_library needs `sdks = ` to get buck to do its thing for tvOS.
This seems like it should be OK since apple_library is a nop on non apple platforms (which makes sense since this is ObjC only) - I think that makes sense anyway?

Summary:
We still need to wait for the `YGUnitPoint` PR to be merged :) But please let me know what you think. One caveat: because of a limitation of Swift, a literal value can be automatically understood as a point-based `YGValue`, but variables have to be explicitly cast. I haven't found a way around it yet:
```
view.yoga.width = 10 // value == 10, unit == YGUnitPixel
let a: CGFloat = 100
view.yoga.height = a // Compiler error
view.yoga.height = YGValue(a) // works, not great
```

Summary:
The main container that gets called `applyLayoutPreservingOrigin:` is using its size as a fixed bounding box.
In some cases it's preferrable to let it accomodate its contents.
This diffs extends `applyLayoutPreservingOrigin:` by adding an additional parameter which can be used to sepecify whether width and/or height are fixed or flexible.
Feel free to suggest better names than `YGDimensionFlexibility` & co.
Let me know if you prefet to kill the API without flexiblity specifier - I'll codemod everything then.

Summary: This is an update of facebook/yoga#368 which was reverted. It fixes support for align-content: strech with multiple lines. The problem with the last attempt at solving this was that align-items:stretch was interfering. We handle this now by detecting when the flex basis of the children hints at them overflowing. This is not 100% correct as the size of the items could change when remeasuring but it will work in 99% of cases.

Summary:
Currently, our configuration of Views looks like this:
```objc
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
view.yoga.isEnabled = YES;
view.yoga.height = 50;
view.yoga.width = 50;
```
Every time that we access `view.yoga` we have to access the associated object on `UIView` to get the `YGLayout`. This adds an extra `objc_msgSend` which increases binary size, and is slight perf impact.
This diff creates a way to modify the `YGLayout` with only a single `objc_msgSend`. Here's the new syntax:
```objc
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
[view configureLayoutWithBlock:^void(YGLayout *layout){
layout.isEnabled = YES
layout.height = 50;
layout.width = 50;
}];
```
Here's the Swift version:
```swift
let view = UIView(frame: .zero)
view.configureLayout { (layout) in
layout.isEnabled = true
layout.height = 50
layout.width = 50
}
```

Summary: While debugging something at Instagram, I kept seeing a UILabel be truncated when it clearly had enough room to display all its' text. What I realized is that during our pixel rounding, we were losing precision because we were using the incorrect rounding function for floats. Changing from `round()` (which is for doubles) to `roundf()` fixed it.

Summary:
Now that the Yoga library supports percentage values, the results returned from it's API were changed.
`YGNodeStyleGetPadding` returns the explicit value that you set, whereas `YGNodeLayoutGetPadding` returns the computed value. Since we are planning to build support for percentages, I'm modifying our API so that it strictly returns the value that was set. As a result:
```
view.yoga.margin = 10;
// view.yoga.margin == 10
// view.yoga.marginLeftWidth == 0
// view.yoga.marginRightWidth == 0
// etc.

Summary:
I did some stylistic changes to the Objective-C unit tests for the following reasons:
- When an equality assert fails, the error messages reads as if the value we are testing is the first argument and the value we expect is the second argument. To improve the readability of test messages, I made sure all `XCTAssertEqual` and `XCTAssertNotEqual` have the arguments in the correct order.
- Because failing equality asserts already comes with a detailed message including the value tested and the expected value, I rewrote several truth asserts on `CGSizeEqual` to two equality asserts on the width and height: when those fail, the error message are clearer.
