Summary:
Added an experimental feature to allow to use only rounded values. See #184. It's not a perfect solution and definitely can be further improved. I'm looking forward to your ideas.

This diff adds a simple python script to generate these enums for all languages. This also makes it much easier to add support for more languages in the future

The gist of the problem is that in css it is fine for a child to overflow a parent if it feels the need to, we were not respecting this.

Summary:
If there is a single child which is flex grow and flex shrink then instead of measuring and then shrinking we can just set the flex basis to zero as we know the final result will be that the child take up all remaining space.
This is a re-land of D4147298. I have updated the diff to check explicitly for exact measure mode to also handle at_most case correctly.

Summary: Scrolling through feed and logging when this optimization is hit leads to... 0 logs. If anything this just adds to confusion. It was initially added due to instinct and not data, which was a mistake. I am happy to add some similar optimization in the future if we have data that it is useful in real world situations, currently it just leads to bugs and confusion though.

Summary:
@public
In the JNI portion of CSSLayout, there's a subtle bug where we were caching the jmethodid of the 'measure' of the first object that had measure called on it. However, if that class had overriden measure, then the jmethodid would be specific to that subclass's implementation and would not work for other classes. Conversely, if a regular CSSNode had been called first, then the super method would be called on the subclass instead of the proper overriden method.
Since there's not really a reason to overriden measure anyway (since you can just provide a different measure function), it's safest to just mark it final and explicitly cache the appropriate methodid

Summary:
@public
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.
