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.

Reverse inheritence between singleton class and its base.
Change singleton template so that the singleton class doesn't inherit
from its base, but rather that the singelton class inherits from the
singleton template. This removes the need to keep the singleton base
classes separate (with the underscore prefix) plus a `typedef` for the
singleton class, and instead makes the class itself become the
singleton. (The exception being intermediate classes that have multiple
other derived classes, which is only the wheeltimer).
This makes for cleaner typing, but requires use of listing the singleton
template as friend class.
No functional changes.

The destructor is good enough, and it removes ambiguity to the
singleton's own dispose method.
No functional changes.

This fixes that:
AmRtpReceiver.cpp: In member function 'virtual void AmRtpReceiverThread::run()':
AmRtpReceiver.cpp:92:7: warning: ignoring return value of 'int pipe(int*)' declared with attribute 'warn_unused_result' [-Wunused-result]

- active sessions and other event receivers
get a SystemEvent::ServerShutdown,
default behaviour of AmSession is setStopped()
- session container waits for all sessions to be ended
- signaling server, rtp receiver, media processor, event dispatcher
are stopped and deleted

* rtp packet parse called in RtpStream, so rtp keepalive packets are not disregarded in respect to rtp timeout
* rtp timeout made configurabe in sems.conf: dead_rtp_time
