When clearing the check for "is bonded" should not be made. If the

When clearing the check for "modified" should not be made, clearing
is in itself a modification, and should always be made.

Joakim Andersson 6de4294aed Bluetooth: host: Fix CCC cfg not cleared when overwriting oldest bond
Fix CCC cfg not cleared when overwriting oldest bond. Calling
bt_unpair with a pointer to the key will result in the key addr being
memset to zero and bt_gatt_clear is called with an zero-set address.
This happens because unpair (hci_core.c) calls bt_keys_clear before
calling bt_gatt_clear.

connection complete event should be set if the own-address type was

In the case where we generate the RPA in the host instead we need to

addresses are used as input to the pairing procedure.

Joakim Andersson 18bee9178f Bluetooth: host: Add non-connectable directed advertising support
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was no longer valid when it was used to start the advertiser.

Joakim Andersson 19434a1056 Bluetooth: host: Do not set adv random address before adv parameters
The LE Set Extended Advertising Set Random Address command may be
issued at any time after an advertising set identified by
the Advertising Handle parameter has been created using the
LE Set Extended Advertising Parameters command.

This commit fixes the advertising set issueing the set random address
command before the advertising set is created in the controller.
Since the le_adv_set_random_addr function has is used to get the the
own address parameter for the it could not simply be moved, and
moving the own address parameter handling out of this function
would create a potentioal maintaince problem.
Also this function is used for both with and without advertising
extension feature so changing it is not trivial without breaking all
the previous random address handling already put in place.
The simplest solution was therefore to postpone the command until the
parameters has been set using 2 flags.
