75f241d0 - Enhance compatibility with proto3 and replace or abstract has_*() methods. (#1778)

Enhance compatibility with proto3 and replace or abstract has_*() methods. (#1778) Enhance proto3 compatibility. Replace has_*() method to corresponding enum handling so we can deal with proto3 generated stream from proto2 code. Add utility wrappers for remaining has_*() methods so we can easily deal with them if/when we switch to proto3.
