kib a8fa279159 ttyfree() frees the cdev(). But if there are pending kevents, ...

filt_ttyrdetach() etc would later attempt to dereference cdev->si_tty,
causing a 0xdeadc0de dereference.  Change kn_hook value from cdev to
struct tty to avoid dereferencing freed cdev.

In ttygone(), wake up select(), sigio and kevent() users in addition
to the queue sleepers.

Return EV_EOF from kevent filters if TS_GONE is set.
