ef7ddc07d3 Bluetooth: controller: Implement macros for vendor assert information
Implement LL_ASSERT_INFO1 and LL_ASSERT_INFO2 for triggering assertions
with parameter information provided for vendor core dump.

Adds Kconfig CONFIG_BT_CTLR_ASSERT_VENDOR by which the new LL asserts
map to BT_ASSERT_VND macros, which shall be implemented in the
debug_vendor_hal.h of the platform. If not enabled, LL_ASSERT_INFO will
map to existing BT_ASSERT_MSG with parameters printed.

Add use of LL_ASSERT_INFO2 where ull_ticker_stop_with_mark() result may
assert.

dca085e155 bluetooth: controller: refactor node_rx_pdu for memory optimization
Generic node_rx_hdr struct contains data not used for done event, so this
pdu specific data is moved to node_rx_pdu to minimize memory usage for
MFIFO_done alloc.

This however calls for a considerable write-through replacing the generic
node_rx_hdr with node_rx_pdu when relevant and needed.

bd5e906f68 Bluetooth: Controller: Fix assertion establishing periodic sync
When the AUX_ADV_IND and AUX_SYNC_IND are close to each
other, the duration between them is not sufficient to
schedule a new instance of ticker to establish
synchronization. This processing time introduces latencies
detected by the prepare callback.

When the sync offset is low, schedule the start of the
reception to next periodic interval.

e458f5aae6 Bluetooth: Use Zephyr standard log system instead of bluetooth/common/log
The `bluetooth/common/log.h` and `bluetooth/common/log.c` files have been
removed. Files that were using them have been updated to use
`zephyr/logging/log.h` instead.

Those replacement have been done consequently:
- `/BT_DBG/LOG_DBG/`
- `/BT_ERR/LOG_ERR/`
- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`

Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.

For files that were including `common/log.h` but not using any logs,
the include has been removed and not replaced.

047b756e64 Bluetooth: df: Add ntf of insufficient resources for IQ samples
According to Bluetooth 5.3 Vol 4, Part E section 7.7.65.21 the
Controller should send an IQ report with Packet_Status set to 0xFF
and Sample_Count to 0x0, to inform Host that it is not able to
store IQ samples for all received Constant Tone Extensions and has
failed to sample at least once.

This commit adds handling of such situation for direction finding
in connectionless mode in lower link layer. It includes:
- lack of node_rx_iq_report to store IQ samples,
- lack of free node_rx to report received advertising data (generates
  an advertising data report with indication "incomplete, no more to
  come" and cancels reception of chained PDUs,
- cancellation of chained PDUs reception due to other scheduling
  reasons.
In all of these situations CTE reception must be enabled and number of
received CTEs is smaller than requested by Host.

If there is not sufficient number of node_rx_iq_report nodes and
report was generated, the CTE will not be samples in a given
periodic advertising synchronization event. The CTE will be
sampled again in next event if there are node_rx_iq_report available.

End user applications may check periodic advertising sync event
counter when use of the reports to be sure about sync event
the received report is connected with.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

bb7a67d5be Bluetooth: Controller: Fix per sync cancel and sync establ synchronize
Current implementation of ll_sync_create_cancel does not allow to stop
synchronization after ull_sync_setup is called. When that is done,
sync->timeout_reload is not zero and the ll_sync_create_cancel will
return BT_HCI_ERR_CMD_DISALLOWED. That means the Controller is able to
cancel periodic advertising synchronization only in period between
call to ll_sync_create and reception of AUX_ADV_IND that has SyncInfo
field.

The Controller should be able to cancell synchronization until first
AUX_SYNC_IND PDU is received and host notified about synchronization
established.

Complete information about synchronization status is provdied by two
ll_sync_set members: node_rx_sync_established and timeout_reload.
These two members of the structure were used in ll_sync_create_cancel
function to do a proper cancel and cleanup.
The node_rx_sync_established member was not cleared when sync was
established or expired. That was required to get a proper information
about synchronization state.

Besides that, to avoid race condition between ll_sync_create_cancel
and ull_sync_established_report, the latter function was extended
to check if cancel operation or sync lost has happened.

5a6ed86d46 Bluetooth: df: Split CTE filtering SYNC_STAT_READY_OR_CONT_SCAN
The SYNC_STAT_READY_OR_CONT_SCAN state into two: SYNC_STAT_READY
and SYNC_STAT_CONT_SCAN. The connected state was used for two
cases:
- synchronization with periodic advertising is already established,
- CTE type is wrong but periodic advertising list is used to filter
synchronized devices.
In the past states were connected because there was only one difference
between them. In case of sync already established, Controller generated
sync report notification to host.The sync was not terminated when
Controller was about to continue search for other periodic advertiser.

The state was split because now Controller terminates sync ticker and
continues search for other periodic advertised. The split improves
readability and makes code easier to understand.

3715241bde Bluetooth: Controller: fix per sync hang if wrong cte and list filter
In case of use of filtering based on: periodic advertising list and
CTE type, the synchronization can hang. That is possible if a periodic
advertiser uses wrong CTE type. In such situation the sync is not
released in ull_sync_done call. What more the sync->timeout_reload
is not cleared and Host is not able to cancel the synchronization.
The periodic advertising is in a semi-sync-established state.
There are no reports send to Host. Host can't use the sync set to
synchronize with other device. It is only able to terminate the
sync (call to ll_sync_terminate).

To fix the issue following changes should be applied:
- isr_rx_adv_sync_estab should call isr_rx_done_cleanup
with sync_term parameter in case the sync_ok isn't SYNC_STAT_ALLOWED.
In any case the CTE type is wrong, no matter is the periodic
advertising list filtering is enabled or not.
- ull_sync_established_report should set sync->is_term to true
in case the CTE type is not allowed. That change is required for devices
that do not support Direction Finding Extension. For those devices CTE
type based filtering is done in ULL by ull_sync_established_report
function. The sync->is_term should be set unconditionally, hence is
moved up in the function.

With these two changes done, ull_sync_done function will execute
sync_ticker_release in case the CTE has wrong type. ULL, depending on
notifications prepared by ull_sync_established_report, will follow up
on sync termination if required.
