Get rid of the msg_peek() function, which has a problem. If there was less data in the socket buffer than requested by the caller, the function would busy loop, as select(2) will always return immediately. We can just receive nvlhdr now, because some time ago we splitted receive of data from the receive of descriptors. MFC after: 1 week
