There are some old Bluetooth modules from Silicon Wave and Broadcom
which support Inquiry Result with RSSI, but do not advertise it. The
core has quirks in the code to enable that inquiry mode. However as
it stands right now, that code is not even executed since entering
the function to determine which inquiry mode requires that the device
has the feature bit for Inquiry Result with RSSI set in the first
place. So this makes this dead code that hasn't work for a long
time.
In conclusion, just remove these extra quirks and simplify the setup
of the inquiry mode to be inline and with that a lot easier to read
and understand.

When the Bluetooth controllers requires an unconfigured state (for
example when the BD_ADDR is missing), then it is important to try
to register the SMP channels when the controller transitions to the
configured state.
This also fixes an issue with the debugfs entires that are not present
for controllers that start out as unconfigured.

Testing cross-transport pairing that starts on BR/EDR is only valid when

this by providing BR/EDR SMP fixed channel over L2CAP. To allow testing

BR/EDR Secure Connections features, introduce a force_bredr_smp debugfs

When controllers set the HCI_QUIRK_INVALID_BDADDR flag, it is required
by userspace to program a valid public Bluetooth device address into
the controller before it can be used.
After successful address configuration, the internal state changes and
the controller runs the complete initialization procedure. However one
small difference is that this is no longer the HCI_SETUP stage. The
HCI_SETUP stage is only valid during initial controller setup. In this
case the stack runs the initialization as part of the HCI_CONFIG stage.
The controller version information, default name and supported commands
are only stored during HCI_SETUP. While these information are static,
they are not read initially when HCI_QUIRK_INVALID_BDADDR is set. So
when running in HCI_CONFIG state, these information need to be updated
as well.
This especially impacts Bluetooth 4.1 and later controllers using
extended feature pages and second event mask page.

Every BR/EDR/LE dual-mode controller requires to have a public address
and so far that has become the identity address and own address. The
only way to change that behavior was with a force_static_address
debugfs option.
However the host can actually disable the BR/EDR part of a dual-mode
controller and turn into a single mode LE controller. In that case
it makes perfect sense for a host to use a chosen static address
instead of the public address.
So if the host disables BR/EDR and configures a static address, then
that static address is used as identity address and own address. If
the host does not configure a static address, then the public address
is used as before.

The optimization for filtering out extended inquiry results, advertising
reports or scan response data based on provided UUID list has a logic
bug. In case no match is found in the advertising data, the scan
response is ignored and not checked against the filter. This will lead
to events being filtered wrongly.
Change the code to actually only drop the events when the scan response
data is not present. If it is present, it needs to be checked against
the provided filter.
The patch is a bit more complex than it needs to be. That is because
it also fixes this compiler warning that some gcc versions produce.

When an adapter is removed (hci_unregister_dev) any pending mgmt
commands for that adapter should get the appropriate INVALID_INDEX
response. Since hci_unregister_dev() calls hci_dev_do_close() first
that'd so far have caused "not powered" responses to be sent.
Skipping the HCI_UNREGISTER case in mgmt_powered() is also not a
solution since before reaching the mgmt_index_removed() stage any
hci_conn callbacks (e.g. used by pairing) will get called, thereby
causing "disconnected" status responses to be sent.
The fix that covers all scenarios is to handle both INVALID_INDEX and
NOT_POWERED responses through the mgmt_powered() function. The
INVALID_INDEX response sending from mgmt_index_removed() is left
untouched since there are a couple of places not related to powering off
or removing an adapter that call it (e.g. configuring a new bdaddr).
