This CL introduced 2 new macros that affect the WebRTC OBJC API symbols: - RTC_OBJC_TYPE_PREFIX: Macro used to prepend a prefix to the API types that are exported with RTC_OBJC_EXPORT. Clients can patch the definition of this macro locally and build WebRTC.framework with their own prefix in case symbol clashing is a problem. This macro must only be defined by changing the value in sdk/objc/base/RTCMacros.h and not on via compiler flag to ensure it has a unique value. - RCT_OBJC_TYPE: Macro used internally to reference API types. Declaring an API type without using this macro will not include the declared type in the set of types that will be affected by the configurable RTC_OBJC_TYPE_PREFIX. Manual changes: https://webrtc-review.googlesource.com/c/src/+/173781/5..10 The auto-generated changes in PS#5 have been done with: https://webrtc-review.googlesource.com/c/src/+/174061.
