When sending a segmented message, the state could get stuck if the
advertising bearer fails in transmitting and we don't detect that it
happened. Add a send_start callback for all packets so we can always
know if sending fails.

When both PB-ADV and PB-GATT are enabled, the PB-ADV code (prov.c)
uses the bt_mesh_proxy_get_buf() API to get a net_buf_simple buffer.
Unfortunately this function also suffers from the same issue that was
fixed by commit 2b273444c1.

In net_app_init_client(), the remote port is set after an initial
set of checks based on the remote_addr's assigned family.
However, if the peer_addr_str is a host name which needs to be
resolved via DNS, the family won't be set yet, and the port is
left as 0.
To fix this behavior let's move the port assignment after the
DNS lookup section to be sure that the remote sa_family is set.

As discovered in https://github.com/zephyrproject-rtos/zephyr/issues/5952
...a duplicate call to k_delayed_work_submit_to_queue() on a work item
whose timeout had expired but which had not yet executed (i.e. it was
pending in the queue for the active work queue thread) would fail,
because the cancellation step wouldn't clear the PENDING bit, causing
the resubmission to see the object in an invalid state. Trivially
fixed by adding a bit clear.
It also turns out that the behavior of the code doesn't match the
docs, which state that a PENDING work item is not supposed to be
cancelled at all. Fix the docs to remove that.
And on yet further review, it turns out that there's no way to make a
test like the one in the linked bug threadsafe. The work queue does
no synchronization by design, so if the user code does no external
synchronization it might very well clobber the running handler. Added
a sentence to the docs to reflect this gotcha.

There's a risk of a deadlock if we use the same pool for ACL fragments

pool.

Zephyr doesn't have luxury to create re-transmit timer per packet. So
it has different methods to handle packets in queue. But re-sending
packets on valid ack messages causing issues.
E.g. A TCP node sent two packets (packet-1, packet-2). Peer replied
two ACKs (ACK-1 and ACK-2), and these two ACK's are at rx_thread
queue. Now ACK-1 is handled and reference of packet-1 is freed
from sent list. Then if condiftion (valid ACK and connection
state is ESTABLISHED) notices that, sent list is not empty.
Restart the timer, modify sent flag and resend packets in a
list. Here packet-2 is sent again, even though ACK-2 is already
received. Situation is worse if there are more packets in the
list.
So only start the re-transmit timer in-case queue is not empty. It
allows rx_thread to handle all incoming packets (in this e.g ACKs).
When the re-trasmit timer expires, it sends the packets which
are left in queue.

The existing implementation assumed DNS resolv callback will be
called just once, but that's not always the case (apparently,
for multi-homes hosts or something). So, apply array bounds
checking (and do pointer arithmetic only after it, as the C

the port number wasn't set in each entry too, so rework how it's
