the direction paramter in case when SEMS
generates local SDP offer or answer.

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.

Because of messy organizing of the code in the function,
it's hard to read that and work with that.

first version, wip.
todo:
- variable number of streams (now fixed to 3 - consumes many ports)
- symmetric RTP
- multi interfaces
- optimization: parse SDP only once, pass AmSdp object with request event
icmpwatcher has not been used for some time, as it is a
quite dangerous method of checking for the remote party
(in the beginning of a call due to delays in signalling,
the port on the remote end could for example still be not
open for some time)

- if an RTP event with timestamps differing from the last one is received, the
event is sent out immediately
- RTP DTMF packets with the same timestamp as an already detected keypress are
ignored.
This allows to raise the value for timeout on sending out RTP DTMF event, to 5 packets
(100 or 150ms)

packets are treated the same as other RTP packets, they are all put into
a map with timestamp as key. However, some UA may use the same timestamp
for all rtpevent packets that represents a digit.

- 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
