Donat Zenichev	8e1a41a9ec	MT#59962 core: introduce new RTP transport model ... This commit introduces a new RTP transport model, based on the AmRtpTransport abstraction, providing a more modular and efficient approach to RTP handling compared to the legacy model. General things: - Introduction of new RTP receiver and transport abstractions - The new model coexists with the legacy RTP handling to preserve backward compatibility Architecture overview: - A new AmRtpTransport layer is introduced to encapsulate RTP transport logic and decouple it from AmRtpStream and session-level code - Transport-specific functionality is implemented via dedicated classes: - AmRtpTransport: base abstraction responsible for RTP/RTCP packet flow, lifecycle management, and interaction with streams - AmRtpUdpSocket: UDP-based RTP socket implementation - AmRtpSocketPair: manages RTP/RTCP socket pairs and their coordination - AmRtpStream is refactored to rely on the transport interface instead of directly managing sockets and low-level I/O Integration details: - SIP session and dialog logic (AmSession, AmSipDialog) is updated to work with the new transport model - SBC call legs and call profiles are extended to support transport selection and lifecycle handling - SDP processing (AmSdp) is updated to reflect transport capabilities and address handling changes This refactoring improves separation of concerns, reduces coupling between RTP streaming and transport mechanics, and provides a cleaner foundation for future RTP extensions and optimizations.
