  Modified files:
    sys/kern             uipc_usrreq.c 
    sys/sys              unpcb.h 
  Log:
  Add two new unpcb flags, UNP_BINDING and UNP_CONNECTING, which will be
  used to mark UNIX domain sockets as being in the process of binding or
  connecting.  Use these to prevent simultaneous bind or connect
  operations by multiple threads or processes on the same socket at the
  same time, which closes race conditions present in the UNIX domain
  socket implementation since inception.
