dcc36c16c2 Bluetooth: Unify helpers for bdaddr_list manipulations
We already have several lists with struct bdaddr_list entries, and there
will be more in the future. Since the operations for adding, removing,
looking up and clearing entries in these lists are exactly the same it
doesn't make sense to define new functions for every single list. This
patch unifies the functions by passing the list_head to them instead of
a hci_dev pointer.

The Authenticated Payload Timeout Expired event is valid for

LE only controllers supporting LE Ping feature. When either of them

the controller was only supporting LE operation.

562064e654 Bluetooth: Fix toggling background scan when changing connectable state
If the connectable state change doesn't require any special HCI commands
the set_connectable_update_settings() function is used instead of the
set_connectable_complete() function. We must therefore make sure to call
hci_update_background_scan() there as well. This code path is used also
when we're powered off, but that's fine since hci_update_background_scan()

e8bb6b9739 Bluetooth: Fix advertising and active scanning co-existence
Many controllers allow simultaneous active scanning and advertising
(e.g. Intel and Broadcom) but some do not (e.g. CSR). It's therefore
safest to implement mutual exclusion of these states in the kernel.

This patch ensures that the two states are never entered simultaneously.
Extra precaution needs to be taken for outgoing connection attempts in
slave role (i.e. through directed advertising) in which case the
operation that came first has precedence and the one that comes after
gets a rejection.

d603b76b0c Bluetooth: Run controller setup after external configuration
When the external configuration triggers the switch to a configured
controller, it means the setup needs to be run. Controllers that start
out unconfigured have only run limited set of HCI commands. This is
not enough for complete operation and thus run the setup procedure
before announcing the new controller index.

This introduces HCI_CONFIG flag as companion to HCI_SETUP flag. The
HCI_SETUP flag is only used once for the initial setup procedure. And
during that procedure hdev->setup driver callback is called. With the
new HCI_CONFIG the switch from unconfigured to configured state is
triggering the same setup procedure just without hdev->setup. This
is required since bringing a controller back to unconfigured state
from configured state is possible.
