So, joining should happen before sending DAD packets, and it should
happen for each unicast address added. This is achieved by joining
from net_if_ipv6_addr_add() call. Note that we already leave

After the Publish Retransmit state was introduced the Publish Period
measurement would begin once the previous Publish message has finished

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

The only generally available model supporting publication that's
convenient to be used for testing is the Health Server Model.
Unfortunately since this model supports period publication, the
non-periodic side got less attention and had some bugs.
The first thing that needs to be done is to verify that the period
returned by bt_mesh_model_pub_period_get() is positive. If it's zero
then no periodic publication should take place.
Another thing that this patch cleans up is the naming of the callback
used for periodic publishing. There's no need do require the callback
to call bt_mesh_model_publish() since this must happen no matter what,
so instead rename the callback from 'func' to 'update' and have the
access layer call bt_mesh_model_publish() if the callback was

Model publication was broken in a couple of ways:
- The Publish Retransmit State was not taken into account at all
- Health Server used a single publish state for all elements
To implement Publish Retransmit properly, one has to use a callback to
track when the message has been sent. The problem with the transport
layer sending APIs was that giving a callback would cause the
transport layer to assume that segmentation (with acks) is desired,
which is not the case for Model Publication (unless the message itself
is too large, of course). Because of this, the message sending context
receives a new send_rel ("Send Reliable") boolean member that an app
can use to force reliable sending.
Another challenge with the Publish Retransmit state is that a buffer
is needed for storing the AppKey-encrypted SDU once it has been sent
out for the first time.To solve this, a new new net_buf_simple member
is added to the model publication context. The separate 'msg' input
parameter of the bt_mesh_model_publish() API is removed, since the
application is now expected to pre-fill pub->msg instead.
To help with the publishing API change, the Health Server model gets a
new helper macro for initializing the publishing context with a
right-sized publishing message.
The API for creating Health Server instances is also redesigned since
it was so far using a single model publishing state, which would
result in erratic behavior in case of multiple elements with the
Health Server Model. Now, the application needs to provide a unique
publishing context for each Health Server instance.
The changes are heavily intertwined, so it's not easily possible to
split them into multiple patches, hence the large(ish) patch.

Some places of the code are interested in when the first advertising
event goes out. Others, on the other hand, are interested when the
last advertising event goes out. Some are even interested in both of
these. Instead of providing a single callback, provide a struct with
two possible callbacks for sending advertising PDUs.

This simplifies the callback implementations since they no-longer need
to do their own look-ups of the needed context.

We've so far been trying to keep the per-buffer mesh meta-data to
a maximum of 8 bytes in anticipation of upcoming net_buf refactoring
that'll have all net_bufs in the system with the same sized user data.
It's however slowly becoming unfeasible to do this - e.g. simply
adding user data to the sending callback would already fill up the
full 8 bytes.
To solve this issue, treat the net_buf user data as just a pointer to
the actual user data, and keep the actual user data in a separate
array. We still keep taking advantage of net_buf_id() however, so
buffers can cheaply be mapped to their meta-data.

Previously, if passive close is peformed, the net context is released
after FIN is received and FIN,ACK is sent. The following last ack from
the peer will be treated as an improper packet, RST is sent to the peer.
This patch refines tcp_established() by centralizing the tcp state
transition and releases the net context only if NET_TCP_CLOSED is
reached.
Besides, the logic that releases the net pkt without appdata (i.e. ACK
or FIN) is moved from packet_received() to tcp_established(). This makes
packet_received() less dependent on the protocol and make the usage of
net pkt more clear in tcp_established().
Fixes: #4901

When testing memq implementation used by controller, a
missing check on NULL pointer return could lead to NULL
pointer deferencing.
Current implementation of controller and mayfly do not
by design lead to NULL pointer dereferencing, this fix
is only for correct-ness and complete-ness.

The common interpretation (among other implementations) seems to be
that Model Publication for a given AppKey Index implies a binding for
that AppKey. This isn't currently explicitly stated in the spec, but
in order to improve interoperability go with this interpretation as
well.

If net_context_recv() returns a error, net pkt will not be released. For
example, net_context_recv() returns -EBADF because the TCP connection is
closed by the peer.
Handle the return value instead of using SET_ERRNO().

Add a command for getting and setting the model publication. We also

There were some needed changes missing after the update to have manual
control of PB-ADV & PB-GATT provisioning bearers. E.g. the test for
CONFIG_BT_MESH_LOW_POWER in net.c was no-longer indicative of scanning
being on or not.
Do the scan enabling selection within the LPN module if LPN is
supported, or otherwise enable scanning unconditionally in
bt_mesh_provision().

The code was completely broken wrt command lookups when the command is
given in the format "<module> <cmd> <args...>". It would only work if
the default module is not set, which is almost never the case (as most
apps set it explicitly).
Refactor the command handling by moving more logic up to shell_exec(),
so that get_cb() does a lookup for a single module
