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.

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 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.
