76c3a8d964 Bluetooth: controller: Fix Peer Address Type in Conn Complete
The LE Connection Complete HCI event, unlike its Enhanced counterpart,
only uses 0x0 and 0x1 for Peer Address Type. Fix it so that it reflects
the specification correctly.

Deprecate BT_LE_ADV defines in hci.h that are expected to be used by the
application in the scan received callback to identify the advertising
PDU type. These defines are mixing HCI input parameters and advertising
PDU types. Internally it is acceptable to mix these, but at the API we
should to mix in them.

e4538c6807 Bluetooth: HCI: Re-organize vendor read static address handling
Add header definition for bt_read_static_addr function. Declaring it
without a header definition will not give any compilation error when
function definition changes.
Refactor nRF SoC specific code into nRF specific source files and
provide weak definitions when these are not implemented. This will make
it easier to add handlers per vendor.

291ebdd4e4 Bluetooth: Fix infinite recursion in host-based bt_rand
Fix infinite recursion in host-based bt_rand function. This would call
HCI LE Random Number command, which would in turn call bt_rand, causing
an infinite recursion.

bt_rand -> prng_reseed -> BT_HCI_OP_LE_RAND -> le_rand -> bt_rand

To solve this issue the controller should avoid doing calls into the
host, so all calls to bt_rand in the controller should be replaced with
a call to a controller function.

Fixes #22202

40c20b1f18 Bluetooth: Change remote version event from prio to normal event type
This commit reverts the change that moved the remote version event from
a priority event to a normal event. This is done because the strategy
for using this event has been changed and will be used with a callback
instead of a semaphore that could be locked from the RX thread.

This commit retains the infrastructure that was added in the controller
so that moving events to priority processing is still possible.

a34d4afe7d Bluetooth: Host: Fix issues with host IRK handling
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.

abd1d047dd Bluetooth: controller: enable dynamic TXP over LL_SPLIT arch (#17731)
This commit targets solving issue #17731 over the LL_SW_SPLIT
arch of the BLE stack in Zephyr. This functionality is exposed
to the user as HCI Zephyr Command extensions

- BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL
- BT_HCI_OP_VS_READ_TX_POWER_LEVEL

which enable Tx power read/write operations within BLE radio events
on a per role/connection basis.

The functionality is enabled upon the Kconfig advanced configuration
triggered by

- BT_CTLR_TX_PWR_DYNAMIC_CONTROL

depending on the enablement of Zephyr HCI vendor-specific command
extensions.

Necessary low-level radio HAL functionality and power definitions
are also supplied to address the high-level functionality of
controlling the Tx power.

0d9dab300e Bluetooth: Introduce separate pool for discardable events
Introduce a separate buffer pool for events which the HCI driver
considers discardable. Examples of such events could be e.g.
Advertising Reports. The benefit of having such a pool means that the
if there is a heavy inflow of such events it will not cause the
allocation for other critical events to block and may even eliminate
deadlocks in some cases.

Also update all mesh samples not to specify explicit RX buffer counts
anymore. Instead, create appropriate defaults in Kconfig so that we
only need to override this in the app for cases like the bbc:microbit
with limited memory.

fc2fcd10cf Bluetooth: Add dedicated pool for HCI_Num_Completed_Packets HCI event
This event is a priority one, so it's not safe to have it use the RX
buffer pool which may be depleted due to non-priority events (e.g.
advertising events). Since the event is consumed synchronously it's
safe to have a single-buffer pool for it. Also introduce a new
bt_buf_get_evt() API for HCI drivers to simplify the driver-side code,
this effectively also deprecates bt_buf_get_cmd_complete() which now
has no in-tree HCI driver users anymore.

58e9ac6811 bluetooth: Controller: Refactor node_rx footer to avoid ptr arithmetic
The old footer was appended after PDU using pointer arithmetic. Now
the footer fields have been moved to the header struct, the
footer fields are now statically located in the data structure,
this is type safe and fields can be referred to by their actual
names rather than indirectly through reference to other members,
thus avoiding pointer arithmetic. Secondly, this change will pave
the way for adding other meta data in the future.
