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.

Rename GTPv2C specifics to gtp2 prefix (#1485) 
In the past only GTPv2C was supported, and had the "gtp" generic prefix.
Later on, GTPv1C support was added, and "gtp1" prefix was used.
Let's move GTPv2C specific bits to have "gtp2" prefix too, and leave
"gtp" prefix for generic stuff among different GTP versions.

Sukchan Lee 13f1b390ae CVE-2021-41794 from NCC Group by Mark Tedman 
When connecting to the UPF port for the PFCP protocol (8805) and sending
an association setup request followed by a session establishment request
with a PDI Network Instance set to ‘internet’, it causes a stack corruption
to occur.

So, ogs_fqdn_parse() fixed.

Sukchan Lee fc27f7499b [SMF/SGW-C] fix the PFCP RR selection (#953) 
The configuration has changed. PFCP node rr=0 is removed as shown below.
sgwc:
  pfcp
    rr: 0 <-- Removed

Introduced a new configuration method for SMF/SGW-C

parameter:
  no_pfcp_rr_select: true

By default, PFCP round robin selection is allowed.
The above parameters prohibit selecting PFCP in a round robin manner.

Sukchan Lee 1bed0d5872 [#568] Add GTP-U Error Indication Handling 
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.

Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.
