selinux: Support for the new TUN LSM hooks
Add support for the new TUN LSM hooks: security_tun_dev_create(), security_tun_dev_post_create() and security_tun_dev_attach(). This includes the addition of a new object class, tun_socket, which represents the socks associated with TUN devices. The _tun_dev_create() and _tun_dev_post_create() hooks are fairly similar to the standard socket functions but _tun_dev_attach() is a bit special. The _tun_dev_attach() is unique because it involves a domain attaching to an existing TUN device and its associated tun_socket object, an operation which does not exist with standard sockets and most closely resembles a relabel operation.
