Summary:
In the persistent version of Yoga, a YogaNode can be shared between two YogaTrees, that means that a YogaNode could have more than one Parent at one point in time. That's why the concept of Parent of a YogaNode is not a 1-1 relationship anymore.
This diff changes the semantic of Parent of a YogaNode to Owner of a Yoga Node. CC sebmarkbage and priteshrnandgaonkar for more context.
Technically this diff renames the field YogaNode.parent to YogaNode.owner (and every internal field, Getter and Setter that is related to parent)
Note that as part of this diff I also modified the CSSLayoutDEPRECATED version of Yoga in order to keep compatibility with the C++ implementation.

Summary:
emilsjolander hi,
this PR solves the following common and probable layout pixel scenario:
the older code is presented for reference:
```java
view.measure(
View.MeasureSpec.makeMeasureSpec(
Math.round(node.getLayoutWidth()),
View.MeasureSpec.EXACTLY),
View.MeasureSpec.makeMeasureSpec(
Math.round(node.getLayoutHeight()),
View.MeasureSpec.EXACTLY));
view.layout(
Math.round(xOffset + node.getLayoutX()),
Math.round(yOffset + node.getLayoutY()),
Math.round(xOffset + node.getLayoutX() + node.getLayoutWidth()),
Math.round(yOffset + node.getLayoutY() + node.getLayoutHeight()));
```
suppose now the following:
- `xOffset + node.getLayoutX() = 2.2`
- `node.getLayoutWidth() = 0.4` ==> `Math.round(node.getLayoutWidth()) = 0`
- `Math.round(xOffset + node.getLayoutX() + node.getLayoutWidth()) = Math.round(2.2 + 0.4) = 3`
this induces, the following measurements:
```java
view.measure(
View.MeasureSpec.makeMeasureSpec(
0,
View.MeasureSpec.EXACTLY),
View.MeasureSpec.makeMeasureSpec(
Math.round(node.getLayoutHeight()),
View.MeasureSpec.EXACTLY));
view.layout(
2,
Math.round(yOffset + node.getLayoutY()),
3,
Math.round(yOffset + node.getLayoutY() + node.getLayoutHeight()));
```
the width measurement of the view is 0, while the layout is `(3 - 2 = 1)`.
my proposed solution is to measure the view the way it is now, but when layouting
I use the `#getMeasuredWidth/Height()` methods, this will stop this problem
from happening.
I also want to note that this bug happens with high probability.

Summary: When some drawing attributes of a view changes how it measures, we need to be able to relayout it correctly. This adds method `invalidate(View)` to `YogaLayout` which will flag the corresponding node as dirty and requiring layout again.

Summary:
You must measure children before you lay them out, and YogaLayout didn't do this. This fixes that.
We also only recompute the yoga tree if the YogaLayout is laid out with a different size to what it's been measured as.
