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.

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.

Add Vendor-Specific-Application-Id in CER for advertising the diameter applications supported (#589) 
* Add Vendor-Specific-Application-Id in CER of PCRF

Not advertising a Vendor-Specific-Application-Id in CER may result in
Diameter Peer rejecting the CER with a DIAMETER_NO_COMMON_APPLICATION error

* Add Vendor-Specific-Application-Id in CER of HSS and MME

Sukchan Lee d73ff77031 We cannot initialize the state in all cases. [#569] 
In TS24.501 Ch 5.5.1.3.8 Abnormal cases on the network side

d) REGISTRATION REQUEST with 5GS registration type IE set to
"mobility registration updating" or "periodic registration updating"
received after the REGISTRATION ACCEPT message has been sent and
before the REGISTRATION COMPLETE message is received.

Since, we have to do this special case, it is desirable
to handle it directly inside the state(gmm-sm.c).
