Adding a generic tty module based largely on the tty driver. This has a new API

and doesn't come with BeOS backwards compatibility. It also has the BeOS compatibility ioctl ops removed and such. I've actually made this back in april, so I don't really remember any more details. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39760 a95241bf-73f2-0310-859d-f6bbb57e9c96
