  SVN rev 196556 on 2009-08-25 21:44:14Z by jilles
  
  Fix poll() on half-closed sockets, while retaining POLLHUP for fifos.
  
  This reverts part of r196460, so that sockets only return POLLHUP if both
  directions are closed/error. Fifos get POLLHUP by closing the unused
  direction immediately after creating the sockets.
  
  The tools/regression/poll/*poll.c tests now pass except for two other things:
  - if POLLHUP is returned, POLLIN is always returned as well instead of only
    when there is data left in the buffer to be read
  - fifo old/new reader distinction does not work the way POSIX specs it
