Summary: stdint.h defines the modern standard c types which have a fixed memory size. This makes the program run more predictably as well as removing the need to ugly double work types such as `unsigned int` or `long long`.

Summary: This moves the api in line with the java api. hasNewLayout makes for sense than shouldUpdate because the API is not telling css layout to update but is instead just a marker for the user of the API to know if there has been a new layout since last time it checked.

Summary:
@public The current CSSLayout can't support RTL because wrong calculation for absolute position.
This change is mainly to fix the issue: https://github.com/facebook/css-layout/issues/197
Three main problems I fixed:
1. Calculate the position in the same way as margin, boarder, and padding. So that to fix the absolute problem.
2. Fix one wrong calculation for leading value when we only know the trailing value. It was hard code for the LTR situation. Now I changed it to depends on the main Axis.
3. Expose getter and setter function for RN to read layout direction and start/end position value.
