This patch introduces two major changes to the directed advertising feature of the bluetooth host. Deprecating the bt_conn_create_slave_le, and removing bt_conn_le_create_slave which has never been released. This behaviour has now been moved by to providing the peer direct address into the advertising parameters. Introducing directed advertising support for nonconnectable directed extended advertising, both scannable and non-scannable. A bug was also fixed in the the directed-adv command in the shell when the argument "low" was given. The advertiseng parameter pointer declared with BT_LE_ADV_CONN_DIR_LOW_DUTY was declared in a scope that was no longer valid when it was used to start the advertiser.
