Constants refactor: public/private constants, replace define (typeless) by real typed constants
Distinguish what's public from private by adding a "_" prefix, this way we don't need to look at the header file to find it out
Grouping and sorting constants
Preifixing public constants with "LR_" to avoid name collision with third party constants
Fixing compile errors, most of these constants are used by LRPortraitUtil.m and must be public
Format everything except auto generated classes
uncrustify
Update liferay-ios-sdk-sample submodule
