s4/drs: Propagate redefinition of drsuapi_DsReplicaOID into code base
The biggest change is that 'oid' field is transmited in binary format.
Also the field name is changed to 'binary_oid' so that
field format to be clear for callers.
After those changes, Samba4 should work the way it works before -
i.e. no added value here but we should not fail when
partial-oid is part of prefixMap transmited from Win server.
Also, thre is a bug in this patch - partial-binary-OIDs are
not handled correctly. Partial-binary-OIDs received during
replication will be encoded, but not handled correctly.
