254c33bac2 Bluetooth: controller: Introduction of RXFIFO composite
By use of the new macro RXFIFO_DEFINE, a complete set of data
structures for supporting a MEMQ'able FIFO with data pool backing is
created. This is intended for RX nodes such as done-events, RX PDU-
and ISO PDU events. The purpose is to simplify the data management
and code complexity, and provide re-usability.

This commit implements the existing done structures (MFIFO, mem pool,
mem link pool) as an RXFIFO. ISO is the next customer, and later the
pdu_rx_free MFIFO- and related pools may be refactored.

f023b5f611 Bluetooth: controller: push topic branch to main
Pushes all work done in the topic-ble-llcp branch into main branch
This is a refactoring of the LL control procedures; the refactored
control procedures are hidden behind a KConfig option and
per default disabled

Goal of the refactoring:

close issue Link Layer Control Procedure overhaul #15256
make it easier to add/update control procedures
Refactoring consists in principal of writing explicit state machines
for the control procedures.
To reduce the risk of regression errors unit-tests have been added

Following control procedures are implemented:

Connection update procedure
Channel map update procedure
Encryption procedure
Feature exchange procedure
Version exchange procedure
ACL termination procedure
Connection parameters request procedure
LE Ping procedure
Data Length Update procedure
PHY update procedure
Min. nr. Of channels used procedure
Constant Tone extension request procedure

fdc92ebb27 Bluetooth: controller: Implement ADV re-schedule for new scheduler
The new JIT scheduler does not have slot reservation, which means that
the ticker extension feature for automatically re-scheduling a colliding
non-anchored event, e.g. ADV, cannot be used.

This implementaion reacts to ADV envent done with result ABORTED or
TOO_LATE, and in those cases attempts to re-schedule the ADV event again
within the 10 ms pertubation window.

As the original scheduling, the re-scheduling is randomized, so there
is no absolute predictability as to how many attempts will be made. The
advertiser will attempt with randomly delayed re-schdules until the
window is exhausted.

If re-scheduling is unsuccessful, the weight of the ADV event is
increased, improving it's chances of success in the next event.

e395c6ce2c Bluetooth: controller: Fix uninitialized ULL reference count
Fix missing initialization of reference count in
ull_hdr_init function.

This has not caused issues so far, but when the ref member
of the struct ull_hdr if placed in the beginning of a
context that is allocated using mem_acquire function then
first few bytes used would make the ref member to have
uninitialized value when such context is allocated by
mem_acquire. First few bytes are the next pointer and free
count stored by the mem module.

The issue was discovered in subsequent commits that
restructure the ULL context structures.

6b72bed967 Bluetooth: Controller: Add common ULL ticker stop with mark function
The same code block for marking an object with
ull_disable_mark, stopping the ticker and then unmarking
the object appeared multiple places; often with a regression
bug where instead of unmarking it in case of error, it would
be "remarked".

This commit fixes the bug, and moves the functionality to
a common function.

1475402d41 Bluetooth: controller: Introduce ULL LLL architecture
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.
