9f82034245 Bluetooth: controller: Introducing slot agnostic ticker
Added config BT_TICKER_SLOT_AGNOSTIC which configures the ticker in
a "slot agnostic" mode, in which no collision resolving or slot
reservation is possible or used. In this mode, the ticker acts as a
simple timer.

f708f861bc Bluetooth: controller: Ticker next slot get to return lazy value
Updated ticker implementation to return lazy value for a
ticker when enumerating active tickers with time
reservations.

This is required to find offsets and to use the lazy value
to correctly calculate event and payload counter values that
needs to be filled into SyncInfo and BigInfo structures.

b56a2d1384 Bluetooth: controller: Add extra data storage for ext. adv. configuration
The storage for extra data is required for implementation of
CTE transmission with periodic advertising.

Data required to transmit CTE correctly are compound of two parts:
- PDU field CTEInfo
- radio configuration to transmit actual constant tone at the end
  of PDU.

Extra data is a storage required for radio configuration data.
Nevertheless it must be in compliance with content of CTEInfo field.
Because of that extra data is stored as part of lll_adv_pdu and
is double buffered like PDU memory.

Bluetooth 5.1 spec. allows to enable or disable CTE TX
and change CTE TX parameters when periodic advertising is
enabled. Besides that CTE TX settings may be set before periodic
advertising parameters are set. In such situation ll_adv_sync_set
may be not yet created.
To overcome these constraints ULL should store CTE TX
settings and forward them to LLL only when CTE TX is enabled.
Because of above reasons ULL stores CTE TX settings in ll_adv_set.

18c01ecae8 Bluetooth: controller: Make random force on lost anchor configurable
Legacy functionality in ull_conn will force scheduling of a connection
which has missed an anchor point due to lost RX. This kicks in either
for previously skipped events (latenzy_event != 0) or at random
depending on the randomness of the AA bit pattern.

This behavior is good at ensuring that a connection with errors or
aborted RX gets prioitized, and helps break locked round-robin
patterns with lost sync, but it also breaks the predictability of
the round-robin ticker scheduling.

With "must_expire" enabled, this feature also kicks in for scheduling
collisions, which may not be desirable.

This commit adds a configuration flag, BT_CTLR_CONN_RANDOM_FORCE, which
is default enabled (legacy behavior).

9ac8dcf5a7 Bluetooth: Call bt_recv from priority higher that TX thread.
A build assert in dummy.c lists the following requirement:
[...] receive thread priority shall be higher than the Bluetooth
Host's Tx and the Controller's receive thread priority.
This is required in order to dispatch Number of Completed Packets

The drivers uses a priority that is equal to the Host TX thread,
and since they don't use the CONFIG define that is only available
to the controller then this BUILD_ASSERT will not catch the
requirement.
