When the SMP context is created all flags default to zero. To determine

Bluetooth: Use lower timeout for LE auto-connections
When we establish connections as a consequence of receiving an

When a controller in an unconfigured state gets removed, then send
Unconfigured Index Removed events.

Bluetooth: Add support for Unconfigured Index Added events
When a controller is in unconfigured state it is currently hidden
from the management interface. This change now announces the new
controller with an Unconfigured Index Added event and allows clients
to easily detect the controller.

Bluetooth: Introduce unconfigured controller state
With the new unconfigured controller state it is possible to provide a
fully functional HCI transport, but disable the higher level operations
that would normally happen. This way userspace can try to configure the
controller before releases the unconfigured state.
The internal state is represented by HCI_UNCONFIGURED. This replaces the
HCI_QUIRK_RAW_DEVICE quirk as internal state representation. This is now
a real state and drivers can use the quirk to actually trigger this
state. In the future this will allow a more fine grained switching from
unconfigured state to configured state for controller inititialization.

Bluetooth: Don't send connection parameters without identity address
If we don't have an identity address for connection parameters it
doesn't really make sense to send them to user space. Instead just
ignore them for now. Later we can add support for sending them when we
eventually get the identity through pairing.

Bluetooth: Make is_identity_address a global function
There are more places that can take advantage of is_identity_address()
besides hci_core.c. This patch moves the function to hci_core.h and
gives it the appropriate hci_ prefix.

Bluetooth: Pass store hint to mgmt_new_conn_param
The calling functions of mgmt_new_conn_param have more information about
the parameters, such as whether the kernel is tracking them or not. It
makes therefore sense to have them pass an initial store_hint value to
the mgmt_new_conn_param function.
