- Since divert protocol is not connection oriented, remove SS_ISCONNECTED flag

Browse Source 
from divert sockets.
- Remove div_disconnect() method, since it shouldn't be called now.
- Remove div_abort() method. It was never called directly, since protocol
  doesn't have listen queue. It was called only from div_disconnect(),
  which is removed now.
