connectable advertisers at a time. This guarantees that we know

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was no longer valid when it was used to start the advertiser.

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.

Handle starting of advertiser and scanner or initiator when advertiser
is using a different identity than the default identity to generate the

We need to handle this only for the privacy case because the random

When privacy is disabled we can return error code from the LE Set Random

Fix multiple issues related to the way the host handles
Identity Information related to privacy
1. If the controller provided a public address the IRK
for this identity would be randomly generated but not
stored persistenly.
2. Fix the handling of the above issue which was fixed
for the random address but would initiate settings save
ID on every boot.
3. Fix the host not using the Vendor Specific HCI commands
related to retrieving the Identity Root (IR) from the
controller and using the key diversified function d1
to generate an IRK as specified in the BT Core spec.
Make sure that a Host generated ID is only saved when it is first
generated.

If the whitelist already exists in the controller then the controller
should not add the device tot the whitelist and should return success.
In that case the counting of entries in the whitelist in the host will
be wrong.
Remove all whitelist counting in the host, and instead rely on the error
reported by the controller for this.
The controller should return error if the whitelist is full.
The controller should return error if use of whitelist was requested but
the whitelist was empty.

This is a moderate redesign of the pending TX packet handling that
aims to eliminate potential deadlocks between the TX thread and the
system workqueue thread. The main changes are:
- TX context (bt_conn_tx) is allocated during buffer allocation, i.e.
not in the TX thread.
- We don't allocate a TX context unless there's an associated
callback. When there's no callback simple integer counters are used
for tracking.
- The TX thread is no longer responsible for TX callbacks or
scheduling of TX callbacks. Instead, the callbacks get directly
scheduled (k_work_submit) from the RX priority thread.
- CONFIG_BT_CONN_TX_MAX defaults to CONFIG_BT_L2CAP_TX_BUF_COUNT,
and in most cases wont need changing. The value now only indicates
how many pending packets with a callback are possible.

Fix race condition in bt_conn_create_le for the state of the scanner in
the Host. This leads to the host issuing a create connection command
without stopping the scanner first. This leads to command disallowed and
failing to establish connection. As well as inconsistent state in the
host which does not allow to stop the running scanner.
The race condition exists because the processing of le_adv_report
handler is done before the thread that called bt_conn_create_le was
woken up to continue after the command_complete event.

The treatment of the BT_DEV_READY flag was broken when used together
with BT_SETTINGS. The flag would get set even though the stack was
still in a partially initialized state. Even worse, for central role
the stack would potentially try to initiate passive scanning without
having an identity address.
Refactor the code that sets the BT_DEV_READY flag (among other
initialization) into a separate bt_finalize_init() helper function and
call it when the settings have been loaded. Also clarify the warning
message given to the user in case settings_load() needs to be called.
