- Hang the scr_stat struct from dev_t.

- Remove sc_get_scr_stat().  It's not necessary anymore.
- Call ttymalloc() to allocate the struct tty for each vty, rather than
  statically declaring an array of struct tty.  We still need a statically
  allocated struct tty for the first vty which is used for the kernel
  console I/O, though.
- Likewise, call ttymalloc() for /dev/sysmouse and /dev/consolectl.
- Delete unnecessary test on the pointer struct tty *tp in some functions.
- Delete unused code in scmouse.c.

WARNING: this change requires you to recompile screen savers!
