ChangeLog:
- SCTPSocket::getLocalAddresses()
   - Fixes and workarounds
- SCTPSocket::internalReceiver()
   - association->ReadReady = (association->hasData() || (getErrorCode(association->AssociationID) < 0));
     ReadReady has to be set in case of error (Shutdown or Abort)
     -> ext_select() will return and recv*() will then return 0
        Otherwise: blocking!
   - Call queue.signal() if notification is left in queue.
- SCTPSocket::setAssocStatus()
   const int ok = sctp_setAssocStatus(assocID,
                                      (SCTP_Association_Status*)&associationParameters);
