  Modified files:
    sys/kern             uipc_mbuf.c uipc_socket.c 
  Log:
  Unbreak writes of 0 bytes.  Zero byte writes happen when only ancillary
  control data but no payload data is passed.
  
  Change m_uiotombuf() to return at least one empty mbuf if the requested
  length was zero.  Add comment to sosend_dgram and sosend_generic().
