159f7dbbb1 lib: net_buf: rename header file from zephyr/net/buf.h to zephyr/net_buf.h
Move the network buffer header file from zephyr/net/buf.h to
zephyr/net_buf.h as the implementation now lives outside of the networking
subsystem.

Add (deprecated) zephyr/net/buf.h header to maintain compatibility with old
file path.

93a6ee501a Bluetooth: Mesh: Add artificial beacon delay
After removing 20ms in advertiser, all subnetwork beacons are sent as high
dense packet of frames with minimal distance between them. That might
cause collisions if beacon interval on devices will coincide.

This commit adds an artificial delay between each subnet advertsing
beacons.

981c79b7ce Bluetooth: Mesh: Drop explicit support for Bluetooth Mesh 1.0.1
Bluetooth Mesh Protocol 1.1 is backward compatible with Bluetooth Mesh
Profile 1.0.1, therefore the stack can still be qualified for 1.0.1 if
needed. But explicit support for both versions requires additional
maintenance efforts and doubles the CI time. To make the stack
qualifiable for 1.0.1, the one needs to remove Private Beacons reception
and compile out SHA256 algorithm support.

What is changed:
- Removed `CONFIG_BT_MESH_V1d1` option.
- Removed `transport_legacy.c` which was using 1.0.1 implementation. The
  new transport layer has new SaR logic that should still be possible to
  qualify for 1.0.1.
- Removed the legacy transport Kconfig options. They are superseded by
  the new transport Kconfig options.
- Tester app: `overlay-mesh-v1d1.conf` is merged into
  `overlay-mesh.conf`.
- Removed BabbleSim tests for 1.0.1.
- Updated documentation.

29895d8275 Bluetooth: Mesh: refactor mesh to use both tinycrypt and psa based crypto
A mesh key type has been added to be able to choose the different
key representation for different security libraries.
The type as well as some functionality related to Mesh key
management has been added as a public API.
If tynicrypt is chosen then keys have representation
as 16 bytes array. If mbedTLS with PSA is used then keys are
the PSA key id. Raw value is not kept within BLE Mesh stack
for mbedTLS. Keys are imported into the security library
and key ids are gotten back. This refactoring has been done
for the network(including all derivated keys), application,
device, and session keys.

dfb8bcaf38 Bluetooth: Mesh: Fix Proxy Privacy parameter support
According to section 6.7, upon connection Proxy Server shall determine
value of Proxy Privacy parameter (sections 6.5 and 7.2.2.2.6). Depending
on that, it will either send Secure Network Beacon or Private Beacon to
Proxy Client, but never both.

Proxy Privacy parameter is determined by GATT Proxy, Node Identity
states and their private counterparts (section 7.2.2.2.6). Since
non-private and private states are mutually exclusive, it is enough to
only check either Private GATT Proxy state or Private Node Identity
state of any known subnet for which the state is currenty enabled.

67a33ed1a0 Bluetooth: Mesh: fix Random value generation for Private Beacons
In `private_random_update`, when first beacon is advertised, there could
be a case when uptime is less then interval * 10s
(`priv_random.timestamp` is equal to 0 for first beacon). Then, Private
Random value will not be generated and will be set to all zeros.

New Private Random must also be generated  before Random Interval
expires, when KR or IVU flags are changed. Reset timestamp to 0 on
`bt_mesh_beacon_update` to generate new Random value.

Do not generate new private random if it won't be used (Private Beacon
state is not enabled).

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.

eca0141152 Bluetooth: Mesh: Isolate cryptographic material
This is a major refactoring of the handling of the cryptographic
material of both the network and transport layers. The aim is to
encapsulate the key object manipulation, and improve overall modularity.

Pulls Applications and Subnets out of the bt_mesh and into separate
modules, with static storage types on the data. This has several
side-effects:
- The Config Server no longer operates directly on the bt_mesh.subs and
  bt_mesh.apps lists, but goes through a public configuration interface,
  following the pattern set in #27908.
- All iteration through the keys is done through iteration APIs
- Key resolution on RX and TX is centralized.
- Changes to the keys triggers events the other modules can register
  handlers for.
- Friendship credentials are stored in the lpn and friend structures.
