[SEPP] Initial Update for 5G Roaming (#2739) 
[SEPP] Initial Update for 5G Roaming

Sukchan Lee 05ed95d623 [GTPU] Fixed PDCP SN handling (#2584, #2477) 
Scenario is handover on S1AP, data forwarding is enabled, and
the Source ENB is forwarding DL PDCP packets to EPC(SGWU)
with PDCP SN included. SGWU is also forwarding these packets
to the Target ENB.

However the PDCP SN is not present in the forwarded packets
from SGWU to Target ENB.

I modified this part, and there was the same problem in 5GC, fixed it as well.

A lot of code in GTP-U has been modified,
so if you have any problems, please let us know right away.

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.

allocate a talloc pool for GTP to ensure it doesn't have to go back
to the libc malloc all the time.

All process will be forcely exited if it failed to encode the S1AP/NGAP/GTP/PFCP message. It is to make sure there was no problem with the encoding of open5gs.

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.

- Set the number of UEs in units of AMF/MME instead of gNB/eNB.
- See default value as shown below
    Number of UEs per AMF/MME : 4,096
    Number of gNB/eNB per AMF/MME : 32
