 Modified Files:
 	src/sys/kern: uipc_socket2.c
 	src/sys/miscfs/fifofs: fifo_vnops.c
 	src/tests/lib/libc/sys: t_poll.c
 
 Log Message:
 - 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.
