64d8713683 Bluetooth: Mesh: use settings priority feature
By using `SETTINGS_STATIC_HANDLER_DEFINE_WITH_CPRIO` we can ensure that
BT subsystems always get loaded after BT, and BT Mesh after both of
them.

This solves the host having to register a GATT service in a delayed
manner, as we are sure to now register the GATT service after sc_commit
sets `SC_LOAD`.

37cac7f2e2 Bluetooth: Host: Use custom API for Bluetooth settings
This commit wrap the `settings_set_one` and `settings_delete` functions
in `bt_settings_store_one` and `bt_settings_delete`. By doing that the
Bluetooth settings can be managed in a single place.

This commit also introduce a new API to manage Bluetooth storage with
`bt_settings_store_*` and `bt_settings_delete_*` functions. Each
Bluetooth settings key have their own store and delete functions. Doing
that so custom behavior for key can be done if necessary.

This change is motivated by a need of keeping track of different
persistently stored settings inside the Bluetooth subsystem. This will
allow a better management of the settings that the Bluetooth subsystem
is responsible of.

e458f5aae6 Bluetooth: Use Zephyr standard log system instead of bluetooth/common/log
The `bluetooth/common/log.h` and `bluetooth/common/log.c` files have been
removed. Files that were using them have been updated to use
`zephyr/logging/log.h` instead.

Those replacement have been done consequently:
- `/BT_DBG/LOG_DBG/`
- `/BT_ERR/LOG_ERR/`
- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`

Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.

For files that were including `common/log.h` but not using any logs,
the include has been removed and not replaced.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

299fac833b Bluetooth: Host: Settings: Handle extra settings_load before bt_enable
Before this change, enabling CONFIG_BT_SETTINGS and calling
settings_load(), but delaying / not calling bt_enable would trigger an
assertion error due to a timeout. The fault is that the settings load
handler for the Bluetooth host assumes bt_enable has already been called
and sends HCI commands to the controller. This times out if HCI is not
running.

The fix is to skip loading Bluetooth settings before bt_enable. The doc
is updated to guide the user on how to enable Bluetooth after settings
have been loaded before.

1. If the controller provided a public address the IRK

   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

   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

2b84c726c8 Bluetooth: Settings: Fix generated identity not persistently stored.
Fix an issue where the generated identity was not permanently stored.
This resulted in being unable to reconnect after bonding when using
privacy, since a new local IRK was generated on reboot.

When settings is enabled the application is responsible for loading
identities and possible creating its own identities.
When settings_load is called and no identities has been created or found
in persistent storage a new identity will be created.
Since bt init has not been finalized bt_id_create will not make a call
to bt_settings_save_id. So we need to make sure that this identity will
be stored.

changed settings_handler_stat type to settings_handler_static type
removed NULL declarations
renamed bt_handler to bt_settingshandler, as bt_handler already exists.
renamed all bt_XXX_handler to bt_xxx_settingshandler to avoid any
overlap.
changed SETTINGS_STATIC_HANDLER_DEFINE() to create variable names from
_hname by just prepending them with settings_handler_.

12a413779d Bluetooth: Fix init procedure handling with BT_SETTINGS
The treatment of the BT_DEV_READY flag was broken when used together
with BT_SETTINGS. The flag would get set even though the stack was
still in a partially initialized state. Even worse, for central role
the stack would potentially try to initiate passive scanning without
having an identity address.

Refactor the code that sets the BT_DEV_READY flag (among other
initialization) into a separate bt_finalize_init() helper function and
call it when the settings have been loaded. Also clarify the warning
message given to the user in case settings_load() needs to be called.

d22b7c9f2d Bluetooth: Remove bt_storage API
The same functionality is now supported by the settings-based
solution, so remove bt_storage out of the way. There were stubs in
bt_storage to handle per-peer information (e.g. pairing keys) but this
was never actually implemented in full. The next step is to add this
support to the settings-based solution.

Leave the code for generating temporary IRK and identity address in
case BT_SETTINGS is not enabled. Also leave the code for using vendor
HCI to read the identity address, in which case the settings
implementation will not touch it.

Introduce a new bt_unpair() API to replace the removed
bt_storage_clear(), since the latter was actually doing more than just
storage management: it was also handling runtime storage of pairing
information. Later, the bt_unpair() implementation will be extended to
clear settings-based pairing storage.

There is one feature that the bt shell module looses: the ability to
give a specific identity address to the "init" command as a parameter.
We might look later in the future if this is really needed, and add a
separate API for this.
