A new version of RTC_EXPORT will be introduced by [1] and it will be used by WebRTC native code. This CL renames the current RTC_EXPORT to RTC_OBJC_EXPORT in order to avoid to mix them. It has been decided to avoid to unify them because RTC_OBJC_EXPORT always marks symbols with default visibility, while RTC_EXPORT will do it only when COMPONENT_BUILD is defined.
