Kernel: Create SelfTTYDevice class to help replace /dev/tty symlink

Browse source 
This will replace the /dev/tty symlink created by SystemServer, so
instead of a symlink, a character device will be created. When doing
read(2), write(2) and ioctl(2) on this device, it will "redirect" these
operations to the attached TTY of the current process.
