Robert Edmonds 7b90330bff Use GOOGLE_LOG(FATAL) instead of GOOGLE_LOG(DFATAL) 
Looking at where these identifiers are ultimately defined [0], it looks
like "DFATAL" means either "ERROR" or "FATAL" depending on whether
NDEBUG is defined. However, looking at the actual code sites in protoc-c
where DFATAL is used, it's not clear why we couldn't just use FATAL
unconditionally.

This is aimed at supporting newer versions of protobuf where the DFATAL
identifier apparently no longer exists.
