8514794ed3 Bluetooth: controller: Do not use LL procedures not supported by remote
Update LLCP handling during PHY update and Data Length update to not
start the LL control procedure if the remote has already indicated that
the procedure is not supported.

This fulfills the following requirement from the BT Core Specification
(Core_v5.2, Vol 6, Part B, Section 4.6):

Except where explicitly stated elsewhere in this specification, if the
peer Link Layer has indicated either during a feature exchange procedure
or by responding with an LL_UNKNOWN_RSP PDU that it does not support a
procedure, then the Link Layer shall not use that procedure.

Re-use the connection parameter request handling for PHY and
data length update procedures.

930d178c69 Bluetooth: controller: enable dynamic TXP over LEGACY arch (#17731)
This commit targets solving issue #17731 over the Nordic LL LEGACY
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.

fff35bd682 Bluetooth: controller: Fix encryption setup to be queueable
Fix the controller implementation to make start encryption
queueable if there is any control procedure in progress.

The context related to encryption procedure is now shared so
that it will be used after the ongoing procedure completes.

The fix here maintains the old functionality of serializing
the queued data and LL Encryption Request PDU, so that data
queued before start encryption is acknowledged.

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
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.

2975ca0754 Bluetooth: Kconfig: Rename CONFIG_BLUETOOTH_* to CONFIG_BT_*
The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.

Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

Subsequent commits will add this feature, by either double
buffering the mode in software or using fast radio ramp up
which gives enough time in the ISR to change the mode.
