901767a47a Bluetooth: Mesh: Shell: Add cfg opt for health srv
Adds Kconfig option for the Mesh Shell Health server.

The shell implementation of Health Server test commands is
dependent on the user adding and initializing the shell Health
Server instance in their application to make the commands functional.
To prevent any confussion about how these commands work, a Kconfig
option has been added to allow conditional compilation of these
commands. In this way the user must actively enable this feature, making
the conditional requirements more clear.

24af6031e2 Bluetooth: Mesh: Use separate pool for relayed messages
Sharing the same pool for both, local and relayed messages has some
disadwantages. In a high-traffic environment the relayed messages may
occupy the whole pool without letting the node to send own messages,
neither to process segmented messages. The vice versa situation is
possible when local messages takes the whole pool so that the node is
not able to relay other messages. Another thing is that it doesn't let
to controll amount of local and relayed messages that the node can send
at once. Controlling the number of messages that the node can relay may
help to reduce the message latency.

This change adds separate net_buf_pool for the relayed messages that
helps to avoid problems described above.

12553800f1 Bluetooth: Mesh: Update defaults - proxy filter, msg cache
This updates the default proxy filter size to 16. Previous value of 3
is too less for the most practical uses and demos. The default proxy
filter type is accept list type and in this mode proxy server rejects
incoming messages from source addresses not in the accept list. The
addresses are added to the accept list when proxy client sends
messages to unicast addresses or manually adds certain addresses to
the accept list. Once this list is full more addresses cannot be added.

This also updates the default network message cache size to 32. The
network message cache helps in preventing duplicate messages getting
repeatedly relayed and helps in reducing unnecessary network traffic.
Previous value of 10 is quite less for most usecases and makes the
node appear to generate much more traffic in mixed network. The
updated value should suffice for most use cases.

Additional explannation is added in Kconfig to help users understand
the significance of this setting.

These two changes result in 176 bytes of additional RAM usage in mesh
samples.

7a2b248b98 Bluetooth: Mesh: Added support for application access to mesh messages
Added bt_mesh_msg_send() which can be used by the application to
directly send model layer messages without local instantiation of
related models. Also added bt_mesh_msg_cb_set() which allows the
application to recieve mesh model layer messages without local
instantiation of related models.

Added bt_mesh_has_addr() which returns a bool. For unicast addresses,
this returns whether or not bt_mesh_elem_find() was successfull. If the
above mentioned bt_mesh_msg_cb_set() has been used by the application to
set a message callback, this returns true so that the stack attempts to
push every model message up to the application via the callback. If no
callback has been set, group addresses are searched to see if the stack
should pass the message up the stack to an instantiated model.

These changes allow applications that do not or can not instantiate
models to interface with models in a mesh network. This is applicable to
applications which act as a Bluetooth mesh gateway, sniffer, debugger,
network monitoring, non-mesh relay/extender, etc.

In app_keys.c friend.c net.c bt_mesh_elem_find() is used only to
determine the existance of an address. The full return value of
bt_mesh_elem_find() is unecessary and so was replaced by the above
mentioned bt_mesh_has_addr() function in these instances.

Simplified bt_mesh_elem_find() by removing the search through group
address. Since the above mentioned bt_mesh_has_addr() function handles
instances where group addresses must be searched, it was no longer
necessary to preform this search in this function.

3a559e972a Bluetooth: Mesh: Modularizing the proxy
The Bluetooth proxy feature includes proxy client
and proxy server. In addition to the proxy pdu
message used above, pb-gatt also uses the same
proxy pdu message.

Currently zephyr bluetooth mesh couples them in one file.

A file at the separation is called gatt_services.c,
which is used to contain Mesh Provisioning Service
and Mesh Proxy Service.
Another file in the separation is called proxy_msg.c,
which is used to process Proxy pdu messages.

Also according to Trond's suggestion:

Rename `CONFIG_BT_MESH_PROXY` to `CONFIG_BT_MESH_GATT`.
Create an additional promptless entry
`CONFIG_BT_MESH_GATT_SERVER` that selects
`CONFIG_BT_MESH_GATT` and is selected by
`CONFIG_BT_MESH_GATT_PROXY` or `CONFIG_BT_MESH_PB_GATT`.

Create additional `CONFIG_BT_MESH_PROXY` used to represent
proxy feature (also include proxy client).

65f798a00a Bluetooth: Mesh: Add API to manually store pending RPL entries
The current approach with storing RPL by timeout doesn't solve all
issues as the node may loss power before the timer is fired.
In addition to that this may wear out flash quickly if short timeout is

This change adds an API to store the pending RPL entry upon user
request. Additional Kconfig option allows to completely disable timer
so that the whole storing relies on the user.

The mesh stack still stays responsible for outdating RPL entries in case
of IV Index update as this happens implicitly for the user.

0335d5fb01 Bluetooth: Mesh: Add OOB Public Key support for provisionee role
This commit allows an unprovisioned device to exchange its public key
using out-of-band techology (see MeshPRFv1.0.1, table 5.19 and section
5.4.2.3).

For in-band public key exchange, the mesh stack uses HCI commands to
generate public and private keys, and DH key. This, however, doesn't
work for OOB public key exchange since there is no command to generate
DH key with a private key provided by an application. Therefore, this
commit adds direct usage of TinyCrypto into the mesh stack for DH key
generation for OOB public key support.

561a8e4f0e Bluetooth: Mesh: Break up mesh settings
The mesh settings.c module is a giant piece of code responsible for
storing the mesh stack configuration. Such approach makes it difficult
to control the data to be stored, breaks the stack modules'
encapsulation by forcing them to reveal the internal kitchen, which
leads to unpleasant issues such as #19799.

This commit moves the responsibility of storing the configuration
to corresponding modules while keeping control of the moment of storing
the configuration and of starting the stack after the settingss loading
is completed.

This doesn't introduce any abstraction between the mesh settings.c and
other modules as it will add more complexity and overhead than necessary
for the actual task.

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.

3c8e5b0e1c Bluetooth: Mesh: Network loopback
Changes the local network interface to exclusively handle packets for
the local interface, duplicating the buffers in the process.

The loopback mechanism now operates its own packet pool for the local
interface queue. The loopback is moved ahead of encryption, allowing the
local interface packets to go back up the stack without network crypto,
saving a full round of encrypt/decrypt for self-send.

Packets for group addresses the local node subscribes to are now
duplicated, with one unencrypted variant going into the network
queue, and the network bound packets following the regular path to the
advertiser.

Introduces one new configuration for setting the number of loopback
buffers.
