Robert Watson 6dd84b0bdc Only poll the fifo for read events if the fifo is attached to a readable
file descriptor.  Otherwise, the read end of a fifo might return that it
is writable (which it isn't).

Only poll the fifo for write events if the fifo attached to a writable
file descriptor.  Otherwise, the write end of a fifo might return that
it is readable (which it isn't).

In the event that a file is FREAD|FWRITE (which is allowed by POSIX, but
has undefined behavior), we poll for both.
