Don't use the ATT structs that has contains only a flexible array
member. This is not supported by C99 standard, only through GNU C

8cc051ccac Bluetooth: host: Change PA sync callbacks to global callbacks
Changes the callbacks for periodic sync callbacks such that multiple
applications can register callbacks, similar to the connection and
scan callbacks.

This change will make it easier to support the PAST feature, as
PA syncs make be created by the controller which then notifies
the host, and thus the application (if callback registered).

Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce

27f6bf19e8 Bluetooth: Host: Change PA sync scan to fast scan
Instead of doing slow (non-fast) scan when syncing to
a PA, it will now do a fast scan, which drastically reduces the

a8f47a1110 Bluetooth: host: Support fragmented L2CAP header
Fixes issue #26900.

A controller may fragment an L2CAP SDUs in any way it sees fit,
including fragmenting the L2CAP header. Likewise, the receiving
controller may send the fragmented header as ACL data to the host.

The Zephyr host assumed that a `BT_ACL_START` was at least 2 bytes long,
and consequently read the two-byte length field from the buffer without
length checks.

This commit allows the `BT_ACL_START` to be less than two bytes,
updating the `conn->rx_len` onces the `BT_ACL_CONT` with the remaining
part of the length field has been received.

76119c526e Bluetooth: GATT: Allow application to add subscription.
Allow the application to add subscription without resubscribing.
This is needed for persistent bonds that can go to deep sleep and
turn of the RAM or power-cycle.
In this case the application as a GATT client must have a way to add
the subscription callbacks back to the stack before the GATT server
sends notifications.
This should preferable be able to be done before even connecting
since the notifications can arrive immediately after connecting to
the peer.
The stack cannot persist this on it's own since it must remember the
function pointers for the callback functions. Storing these in
persistent storage would not be compatible with a Device Firmware
Upgrade (DFU) solution.

e997c46e6d Bluetooth: GATT: Handle bt/ccc setting with CCC lazy loading
When lazy loading of CCCs are enabled there is no settings set handler
register for the 'bt/ccc' key, this means that the settings set handler

This results in an error message logged by the settings subsystem.
  "E: set-value failure. key: bt/ccc/f8c39e2f98210 error(-2)"
