Problem conclusion

Temporary fix

Comments

• The #define MSG_CONNTERM  0x80 is added to the sys/socket.h
  C/C++ header file.
  
  The following documentation updates are made:
  z/OS V1R13.0 XL C/C++ Run-Time Library Reference
  SA22-7821-13
  
  Add the following to the "flags" Parameter Description of the
  following functions:
  recv()
  recvfrom()
  recvmsg()
  
  MSG_CONNTERM - The asyncio will not complete until the socket
    session ends.  Note: The buffer size must be 0 and the
    other MSG_FLAGS may not be used.
    - This flag provides a way to be notified at the time
    that a TCP socket session ends, independent of any actual
    receive-type operations outstanding on the socket.
    - Any other outstanding requests will also be completed
    at connection termination.
