 Log Message:
 Pull up following revision(s) (requested by thorpej in ticket #1350):
 
 	sys/kern/uipc_socket2.c: revision 1.140
 	tests/lib/libc/sys/t_poll.c: revision 1.5
 	sys/miscfs/fifofs/fifo_vnops.c: revision 1.87
 
 - fifo_poll(): If the last writer has disappeared, detect this and return
   POLLHUP, per POSIX.
 - fifo_close(): Use the new fifo_socantrcvmore(), which is like the
   garden-variety socantrcvmore(), except it specifies POLL_HUP rather
   than POLL_IN (so the correct code for SIGIO is sent).
 - sowakeup(): Allow POLL_HUP as a code (notifies poll'ers with POLLHUP).
 - Add test cases for correct POLLHUP behavior with FIFOs.
 
 Fixes PR kern/56429.
