Victor Boivie 306b1393cb Optimize set of registered SSRCs in RTCPReceiver
In highly loaded media servers, RTCPReceiver's use of std::set
attributes to ~0.87% CPU. It's mostly ::find and the [] operator and the
assignment operator.

 * Removed locking of a mutex in `TriggerCallbacksFromRtcpPacket``
   as it copied members that were already const.
 * Switched the use of std::set for the list of registered local SSRCs
   to an absl::InlinedVector, as the set is very small and it's not
   expected that any more complicated container would be faster than a
   linear search within a cache line.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
