  Modified files:
    sys/kern             kern_descrip.c uipc_socket2.c 
    sys/net              rtsock.c 
    sys/netinet          accf_data.c accf_http.c tcp_input.c 
    sys/netkey           keysock.c 
    sys/sys              filedesc.h socketvar.h 
  Log:
  Add a global sx sigio_lock to protect the pointer to the sigio object
  of a socket.  This avoids lock order reversal caused by locking a
  process in pgsigio().
  
  sowakeup() and the callers of it (sowwakeup, soisconnected, etc.) now
  require sigio_lock to be locked.  Provide sowwakeup_locked(),
  soisconnected_locked(), and so on in case where we have to modify a
  socket and wake up a process atomically.
