IED Server/Goose: Fix the 'Goose Ethernet Interface Id' allocation
...
Issue:
In the case of 'GooseInterfaceId' initialization for all GOOSE
publishers (API function: IedServer_setGooseInterfaceId()), only the pointer of
the character string is saved and used for the next operations.
If the corresponding memory is cleared or overwritten in the
application program, a segfault may occurred in libiec61850.
Proof:
In the 'server_example_goose.c' example, if we used a temporary
allocated memory to store the 'ethernetIfcId', the bug will occur:
/* set GOOSE interface for all GOOSE publishers (GCBs) */
+ unsigned int ethernet_interface_id_length = strnlen(ethernetIfcID, 32);
+ char * tmp_ethernet_interface_id = calloc(sizeof(char), ethernet_interface_id_length + 1);
+ memcpy(tmp_ethernet_interface_id, ethernetIfcID, ethernet_interface_id_length);
+
IedServer_setGooseInterfaceId(iedServer, tmp_ethernet_interface_id);
+
+ explicit_bzero(tmp_ethernet_interface_id, ethernet_interface_id_length);
+ free(tmp_ethernet_interface_id);
(This issue was discovered during the rewriting of 'server_example_goose'
in Python, with the Swig wrapper: the allocated memory for
'ethernetIfcID' parameter in the Swig wrapper is automatically reused)
Fix:
The 'gooseInterfaceId' attribute of 'MmsMapping' in libiec61850 must be a new
allocated memory (with the use of 'StringUtils_copyString()') and deallocated
in the 'MmsMapping_destroy()' function.

There is an access error while using iec61850_client_example1 with server_example_basic_io.
From [1]:
/* write a variable to the server */
value = MmsValue_newVisibleString("libiec61850.com");
IedConnection_writeObject(con, &error, "simpleIOGenericIO/GGIO1.NamPlt.vendor", IEC61850_FC_DC, value);
The error code is IED_ERROR_ACCESS_DENIED = 21.
By default access to variables with FC=DC and FC=CF is not allowed, fix this
by changing the access policy as suggested by [2].
