Sukchan Lee a667525041 [GTP/PFCP]] incorrect dst TEI=0/SEID=0 (#3043) 
If eg. PCRF or AAA diameter link is not yet ready (eg. PCRF crashed), and
a client sends a CreateSessionRequest announcing its ow F-TEID,
then open5gs-smfd answers with Create Session Response Cause=
"Remote peer not responding", but it is not setting the received F-TEID
in the header of the response, instead it sends with TEI=0.

As a result, the peer cannot match the CreateSessionResponse, and needs
to rely on its own timeout timer to figure out that specific request failed.

This also happens in PFCP, so to solve this problem, I added teid/seid_presence
to the interface that sends the error message as shown below.

void ogs_gtp2_send_error_message(ogs_gtp_xact_t *xact,
        int teid_presence, uint32_t teid, uint8_t type, uint8_t cause_value);
void ogs_pfcp_send_error_message(
    ogs_pfcp_xact_t *xact, int seid_presence, uint64_t seid, uint8_t type,
    uint8_t cause_value, uint16_t offending_ie_value);

[SMF] pfcp: Retrieve sess when response with SEID=0 is received (#1620) 
3GPP TS 29.244 7.2.2.4.2 documents that the peer will set SEID=0 in the
response when we request something for a session not existing at the peer.
If that's the case, we still want to locate the local session which
originated the request, so let's store the local SEID in the xact when
submitting the message, so that we can retrieve the related SEID and
find the session if we receive SEID=0.

Sukchan Lee c6c8dc1256 [PFCP] Support Multi-CP with One-UP 
A problem occurred when there was one SGWU/UPF and multiple SGWC/SMF.

When SGWU and UPF create a session, if the SEID is the same,
the existing session information is used without creating an additional session.

These problems were solved by using the F-SEID including IP information
in the process of checking the existing session.

Sukchan Lee e0a487f479 [SMF] Optimiza Session Modification Message 
For video in VoNR, multiple QosFlow is required in one session.

In the past, since only one Session Modification Message was supported,
QoS-Flow was put into several Session Messages one by one and processed.

Now that multiple QoS-Flows can be supported,
it is optimized to process one session modification message.
