Carles Cufi f7d313b154 Bluetooth: Controller: Add ASSERT info dump on HCI builds
When building Zephyr in the controller-only configuration,
assertions that happen in the Link Layer code are not visible
to the Host which is running on another HCI and connected via
UART or USB to it. This patch allows the Controller code
to output the assertion line number when in such a configuration,
allowing the Host to view the event to help debugging.

The event format used is temporary and will be replaced by a
standardized Vendor Specific specification to come at a later
time.

Luiz Augusto von Dentz 629ab2da6b Bluetooth: ATT: Fix not forwarding error properly
When retrying the request due to a security error that can fail but since
the original buffer was freed in the process the code can no longer verify
if the opcode matches thus it always fails BT_ATT_ERR_UNLIKELY instead of
using the response error, so this not longer cares about the opcode and
just use the response error always.

Carles Cufi 6ccfa64b5c Bluetooth: Controller: Handle LL_UNKNOWN_RSP PDU for remote features
When a peer controller does not recognize one of the LL control
PDUs received, it will issue an LL_UNKNOWN_RSP PDU to let the
peer know that it does not recognize the request.
The controller now handles this incoming PDU and completes the
procedure by issuing the appropriate HCI event in the case of
an LL_FEATURE_REQ and _RSP pair.

Johan Hedberg 77a8516dd2 Bluetooth: storage: Add basic support for internal storage
Add basic implementation of an internal storage handler that uses the
local file system. The root directory for all Bluetooth related data
is /bt. Each remote device has its own subdirectory and each key its
own file. This helps keep the implementation very simple, but does
come with the meta-data overhead for each file.

As an example, the value of a key 0x0001 for a device with a static
random address cc:11:22:33:44:55 would be stored in the following
file: /bt/cc11223344551/0001. Local values such as the identity
address are stored directly under /bt with a file name that matches
the key the same way as remote-device files.

For full functionality the implementation requires a file system that
can support file/directory names of up to 13 characters in length. If
the file system supports less than that (as is the case with FAT12)
then only local values can be stored (in /bt/abcd). Local values
include the identity address as well as the local IRK.

Benjamin Walsh 8cf56bcac7 unified: dissociate system workqueue from common workqueue module
Making a reference to the common work queue code should not necessarily
drag in the system workqueue, since it is possible to use a workqueue
that is not the system workqueue. This is done by moving the system
workqueue into its own code module.

Moving the system workqueue to its own code module allows removing the
NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the
common workqueue code and system workqueue all the time. They are only
linked in the final image if a reference to them exist, same as the
other kernel modules.
