14a81bf021 Bluetooth: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language extension
to the C90 standard, but the preferred mechanism to declare variable-length
types such as these ones is a flexible array member.

bc292258c5 Bluetooth: Add support for reading security information
To allow userspace to make correcty security policy decision, the kernel
needs to export a few details of the supported security features and
encryption key size information. This command exports this information
and also allows future extensions if needed.

00bce3fb06 Bluetooth: Enable erroneous data reporting if WBS is supported
This change introduces a wide band speech setting which allows higher
level clients to query the local controller support for wide band speech
as well as set the setting state when the radio is powered off.
Internally, this setting controls if erroneous data reporting is enabled
on the controller.

600a87490f Bluetooth: Implementation of MGMT_OP_SET_BLOCKED_KEYS.
MGMT command is added to receive the list of blocked keys from
user-space.

The list is used to:
1) Block keys from being distributed by the device during
   the ke distribution phase of SMP.
2) Filter out any keys that were previously saved so
   they are no longer used.

To make the behavior predictable when attempting to pair with a device
for which we already have a Link Key or Long Term Key, this patch adds a
new 'Already Paired' error which gets sent in such a scenario.

93690c227a Bluetooth: Introduce controller setting information for static address
Currently it is not possible to determine if the static address is used
by the controller. It is also not possible to determine if using a
static on a dual-mode controller with disabled BR/EDR is possible or
not.

To address this issue, introduce a new setting called static-address. If
support for this setting is signaled that means that the kernel supports
using static addresses. And if used on dual-mode controllers with BR/EDR
disabled it means that a configured static address can be used.

In addition utilize the same setting for the list of current active
settings that indicates if a static address is configured and if that
address will be actually used.

With this in mind the existing Set Static Address management command
has been extended to return the current settings. That way the caller
of that command can easily determine if the programmed address will
be used or if extra steps are required.

The 'master' parameter of the New CSRK event was recently renamed to
'type', with the old values kept for backwards compatibility as
unauthenticated local/remote keys. This patch updates the code to take
into account the two new (authenticated) values and ensures they get
used based on the security level of the connection that the respective
keys get distributed over.

provides the set_bdaddr callback, this allows changing the device
address before powering on the controller.

This patch introduces a new Mgmt event called "New Connection Parameter".
This event indicates to userspace the connection parameters values the
remote device requested.

The user may store these values and load them into kernel. This way, next
time a connection is established to that device, the kernel will use those
parameters values instead of the default ones.

This event is sent when the remote device requests new connection
parameters through connection parameter update procedure. This event is
not sent for slave connections.
