Fix multiple issues related to the way the host handles
Identity Information related to privacy
1. If the controller provided a public address the IRK
for this identity would be randomly generated but not
stored persistenly.
2. Fix the handling of the above issue which was fixed
for the random address but would initiate settings save
ID on every boot.
3. Fix the host not using the Vendor Specific HCI commands
related to retrieving the Identity Root (IR) from the
controller and using the key diversified function d1
to generate an IRK as specified in the BT Core spec.
Make sure that a Host generated ID is only saved when it is first
generated.

Fix deadlock in Bluetooth Host. Deadlock could happen from the SMP
callbacks when calling Bluetooth API functions. This is because the
callbacks was given directly from the HCI TX thread. If the calling
API function resulted in trying to send a new HCI command it would post
this HCI command to the HCI TX thread and then wait for command complete
event. This would result in the HCI TX thread blocked waiting for the
itself to process the command.
Example:
Calling bt_conn_le_conn_param_update from pairing_complete callback.

Move initiating security functionality and LTK requesting into the SMP
module so that SMP can track when the connection is in the encryption
process

SMP shall be considered internal TX notify callbacks so they are
allowed to be run from TX thread context like the others.

Give the security changed callback when the peripheral initiated
security request and peer attempted to encrypt the connection but no LTK
match was found.

The call to bt_conn_security will send a SMP security request for
peripheral, and for central it will initiate LL encryption.
A call to bt_conn_security with no IO capabilities but authenticated
keys has been distributed, would succeed on central side, but fail on
peripheral side with error code -22.
The keys could have been either:
- Preprogrammed
- IO capabilities may have changed.
- OOB bonding may been used.
Fix so that Peripheral can send a security request if the bond
information is already established.

Added support for the LE SC pairing with the OOB data. The peripheral
side is only supported for now.

This fixes a regression introduced in commit 6af5d1cd1f
("Bluetooth: Compress bt_keys struct").
Instead of passing a value zero as the random number, the
value at the RAM address zero was being used by the start
encryption function call. It is now fixed by consistently
using byte-array to store EDiv and Rand values.

Since more and more code is going to be reused by both the Host and the
Controller, this commit introduces a common/ folder that will contain
everything that is not tied to one of the two components but shared by
them.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Move the Bluetooth host stack from net/bluetooth to
subsys/bluetooth/host. This is preparation for having both host and
controller under the same root, i.e. subsys/bluetooth/.
