    [SMF] introduce new list API [#1019]

herlesupreeth 4d6692d8fe fix: DRB lost issue when additional TFTs needs to be added to existing bearer with TFTs 
This commit address the issue where a bearer with particular
PCC rule name exists with TFTs and addtional TFTs needs to be added
to same bearer and DRB lost is reported by UE.

This is achieved by creating EPS Bearer Level Traffic Flow Template
with TFT operation code as 'OGS_GTP_TFT_CODE_ADD_PACKET_FILTERS_TO_EXISTING_TFT' in
above scenario rather than use 'OGS_GTP_TFT_CODE_CREATE_NEW_TFT' at all times.
And, not remove existing packet filters for the bearer.

Sukchan Lee cc03c91bdd [AMF] 5G-GUTI generation changed (#910) 
The AMF shall assign a new 5G-GUTI for a particular UE:
a) during  a successful initial registration procedure;
b) during a successful registration procedure
   for mobility registration update; and
c) after a successful service request procedure invoked as a response
   to a paging request from the network and before the release
   of the N1 NAS signalling connection as specified in subclause 5.4.4.1.

The AMF should assign a new 5G-GUTI for a particular UE
during a successful registration procedure
for periodic registration update. The AMF may assign a new 5G-GUTI
at any time for a particular UE by performing
the generic UE configuration update procedure.

no Requested NSSAI was provided or none of the S-NSSAIs
in the Requested NSSAI are permitted,
i.e. do not match any of the Subscribed S-NSSAIs or not available
at the current UE's Tracking Area (see clause 5.15.3).

Sukchan Lee 776d323a16 fix: Change UE Context Request IE handling (#771) 
Previously, AMF would sends PDUSessionResourceSetupRequest
when the following conditions were met:
- gNB didn't send UE Context Request IE of InitialUEMessage
- AMF should send SMF generated TRANSFER message(PDU_RES_SETUP_REQ)
to the gNB

However, in issues #771, the gNB did not accept
PDUSessionResourceSetupRequest. Perhaps the gNB engineer thought
that if gNB needs to send data traffic to the UE, AMF should send
an InitialContextSetupRequest regardless of UE Context Request IE.
This is because gNB requires the kgNB security context
for data connection.

So, in this case, Open5GS-AMF decided to send
an InitialContexSetupRequest regardless of
whether it received UE Context Request IE of InitialUEMessage.

Sukchan Lee 6f11a78079 If SCTP use SOCK_STREAM, Use BUFFERING method. 
Most of the time, an application wants to perform some amount of data buffering
in addition to just responding to events. When we want to write data,
for example, the usual pattern runs something like:

1. Decide that we want to write some data to a connection;
   put that data in a buffer.
2. Wait for the connection to become writable
3. Write as much of the data as we can
4. Remember how much we wrote, and if we still have more data to write,
   wait for the connection to become writable again.

Now, Open5GS implements the above method by default when transmitting data
in a stream type socket.

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.
