Sukchan Lee da5d424ed9 [MME] Incorrect behavior of SGsAP+Dedicated-Bearer (#3072) 
First of all, it crashes when creating a Dedicated Bearer
on the default Session that is created for the first time.
This behavior should be possible, so the related ASSERT is removed.

Next, the InitialContextRequest is modified
during the Attach Request to include the first Bearer.

Finally, there was an issue where trying to create a Dedicated Bearer
with SGsAP enabled resulted in an InitialContextSetupRequest message
with a PTI of zero. This is because MME initializes the PTI to 0
upon receiving the Create Bearer Request while processing SGsAP.

All of these issues has been fixed.

Sukchan Lee 390a9dd637 [MME] incorrect behavior of the SGsAP 
1. According to ETSI TS 129 118 4.1, if the Network Access Mode (NAM) is set
   to "Packet only," no SGs association should be established.

2. If the NAM is set to "Packet and Circuit," and the SGs association is
   rejected by the CS core, this rejection should only impact
   the SGs association itself and not result in a UE attach rejection
   for a UE with a valid HSS account.

Sukchan Lee 79d46be086 Introduced Subscription identifier de-concealing 
o Generate the private key as below.
   $ openssl genpkey -algorithm X25519 -out /etc/open5gs/hnet/curve25519-1.key
   $ openssl ecparam -name prime256v1 -genkey -conv_form compressed -out /etc/open5gs/hnet/secp256r1-2.key

 o The private and public keys can be viewed with the command.
   The public key is used when creating the SIM.
   $ openssl pkey -in /etc/open5gs/hnet/curve25519-1.key -text
   $ openssl ec -in /etc/open5gs/hnet/secp256r1-2.key -conv_form compressed -text

In ausf/udm.yaml

 hnet:
    o Home network public key identifier(PKI) value : 1
      Protection scheme identifier : ECIES scheme profile A
    - id: 1
      scheme: 1
      key: /etc/open5gs/hnet/curve25519-1.key

    o Home network public key identifier(PKI) value : 2
      Protection scheme identifier : ECIES scheme profile B
    - id: 2
      scheme: 2
      key: /etc/open5gs/hnet/secp256r1-2.key

    - id: 3
      scheme: 1
      key: /etc/open5gs/hnet/curve25519-1.key

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.
