Move GCC attributes into a centraized defines

Instead of having ifdef __GNUC__ all over the headers
to use special compiler's hints use a special file where
all things like this are concentrated.

Makes code easier to follow and allows to manage special
attributes in more efficient way.

Thanks Campbell for review!
