578dbe1c0a Bluetooth: Mesh: Support reliable sending when publishing
Until now the choice of reliable sending (segmented messages with
acks) was implicitly dependent on the size of the payload. Add a new
member to the bt_mesh_model_pub to force using segment acks even when
the payload would fit a single unsegmented message.

46a95f12ad Bluetooth: Mesh: Add database for managing nodes and keys
Refactor the handling of network nodes and their keys into a separate
Mesh Configuration Database (CDB). This, not only creates a separation
of the local node and the other nodes, but also makes it possible to
implement functions to manage the whole, or at least parts of the mesh
network.

19718fd6da Bluetooth: Mesh: Skip publish if update fails
Allow models to skip a periodic publish interval by returning an error
from the publish update callback.

Previously, an error return from publish update would cancel periodic
publishing. This can't be recovered from, and as such, no valid model
implementation could return an error from this callback, and there was
no way to skip a periodic publish.

723e14a432 Bluetooth: Mesh: Model start callback
Replaces the Mesh model settings_commit callback with a start callback,
indicating that the mesh model behavior is ready to start. Everything
that was previously done in the settings_commit callback may be moved to
this callback, which gets called just after mesh settings are committed,
instead of in the middle of the process.

This resolves an issue where models had no context in which to start
their behavior, as the previous settings_commit call fired before the
mesh was declared valid, making access APIs inaccessible.

306ac6dd1e bluetooth: doc: Cleanup warnings with doc build
Doxygen 1.8.15 or greater has a number of warnings of the form:

  warning: argument 'net_idx' from the argument list of
  bt_mesh_health_period_set has multiple @param documentation
  sections

This is due to the use of @copydetails bt_mesh_health_period_get
which ends up copying all of the details from
bt_mesh_health_period_get which has some of the same @params as
bt_mesh_health_period_set.  To make the generated docs look clean
the easiest is to remove the @copydetails and just copy the
comment.

2d859cc147 Bluetooth: Mesh: Make model publication struct more compact
commit 42d330406e introduced the FastPeriodDivisor value to
to the model publication struct. Based on the way it was grouped it
seems the intention was to fit it within the same octet as other bit
fields, but it actually makes the octet overflow by one bit. This ends
up creating another u8_t variable which in turn adds 24 bits of
padding after it.

To keep the size of the struct as compact as possible, group the flag
together with the key index, since that only requires 12 bits. Some
care is needed here, since the mesh stack does have special internal
key index values that require more than 12 bits such as
BT_MESH_KEY_UNUSED and BT_MESH_KEY_DEV. In this case restricting
ourselves to 12 bits is fine since the value in the model publication
struct follows 1:1 the value received in the Config Model Publication
Set message, and there the parameter is defined to be exactly 12 bits.

0151d6dc33 Bluetooth: Mesh: Model extension concept
Adds the model extension concept to the access layer, as described in
the Mesh Profile Specification, Section 2.3.6. Extensions are
implemented as a tree, using two pointers in each model:

The extends pointer points to the first extended model, and the next
pointer points to the next sibling or (if the NEXT_IS_PARENT flag is
set) the parent model in the tree, forming a cyclical "Left-child
right-sibling" (LCRS) tree. The tree root can be obtained by calling
bt_mesh_model_root_get(), and the extended models can be walked by
calling bt_mesh_model_tree_walk().

According to the Mesh Profile Specification Section 4.2.3, all models in
the same extension tree share one subscription list per element. This is
implemented by walking the model's extension tree, and pooling the
subscription lists of all models in the same element into one. If the
config server adds a subscription to a model, it may be stored in any of
the model tree's models' subscription lists. No two models in the same
extension tree and element will have duplicate groups listed. This
allows us to increase extended models' capacity for subscriptions
significantly.

80669decce Bluetooth: Mesh: Add support for provisioner role over PB-ADV
Make it possible to provision devices over advertising bearer (PB-ADV).
Many messages in the provisioning protocol are the same for provisioner
and device so much of the code could be reused by only changing when
they are expected to arrive.

This introduces to concept of local and remote device keys. The models
for cfg_cli and cfg_srv have been updated to reflect this concept. Both
the send and receive path in the transport layer have been updated to
support encrypting/decrypting with local and remote device keys.

When a node has been provisioned it is stored in bt_mesh_net.nodes. If
CONFIG_BT_SETTINGS is enabled, they are also saved to settings. If the
callback node_added in bt_mesh_prov has been set, it will be called for
every node that gets provisioned. This includes when they are retrieved
from settings.

The configuration CONFIG_BT_MESH_NODE_COUNT controls how many nodes that
can be provisioned.

42d330406e Bluetooth: Mesh: Fix qualification test MESH/SR/HM/CFS/BV-02-C
The commit 8d0ef1eb85 attempted to fix
test case MESH/SR/HM/CFS/BV-02-C, however inadvertently ended up
introducing a hidden bug. This bug was unearthed thanks to commit
686f5c79cf. We have to keep always track
of the FastPeriodDivisor state whether we're using it (faults > 0) or
not (faults == 0). Introduce a boolean field to the model publication
that's used to indicate whether the FastPeriodDivisor should be
applied or not, instead of zeroing the divisor when there are no
faults (this would cause wrong behavior when faults appear again).

Additionally, the PTS seems to require that we wait until the end of
the existing period before sending the next Health Current Status,
rather than sending it immediately when the fault count changes.

ed5fb3ff37 Bluetooth: Mesh: Fix (re)transmit interval handling
The adv_send() function was incorrectly decoding the 5-bit value (it
was using it directly as milliseconds), which effectively lead to the
code always picking the controller's minimum supported interval.

Fix this issue, but do it by simplifying the (re)transmission state
tracking so that the state is always stored in the original "packed"
8-bit value, where 5 bits are reserved for the interval, and 3 for the
count.

15fe221f13 Bluetooth: Mesh: Fix accuracy of Publish Period
After the Publish Retransmit state was introduced the Publish Period
measurement would begin once the previous Publish message has finished
transmitting. This will however cause inaccurate periods, which is
particularly an issue with the PTS that expects accuracy of less than
0.5 seconds (apparently).

Since the publication timer is also used for the retransmissions we
can't simultaneously use if for the period as well. Therefore, we
introduce a new variable called period_start which makes a note of
when the period was supposed to start, and then once all
retransmissoins are done initializes the timer with the send duration
taken into account.
