There's not need to mark advertising set as created by either legacy

HCI advertising mode which determines whether host uses legacy or

When a connect indication contains a channel map of all zeros, the
adv->conn is left NULL'ed after return and next connect attempt leads
to a crash.

When a must-expire ticker callback is executed, it is important not to
call the LLCP state machine, as the lazy state is unavailable. The code
must rely on the next proper event to call ull_conn_llcp with an updated
non-zero lazy count.

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.

Port the implementation that performed random backoff of

When peer master implementation skips events, multiple

the chance of synchronizing with their masters again.

The the footer structure and extra bytes (rssi, resolving index etc.)
were overlapping in memory, rx_ftr was moved into the header, but the
extra and footer are still being read from the same place, extra was
written to the end. So this avoided memory corruption, but reading extra

There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.
This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.
All files that use these macros have been updated.

This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.
This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.
The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.
