During the CoAP API change, slight changes were made the ref / unref
packet pending process. Let's re-align with the coap-client sample
in how we apply the packet refs in retransmit_request() and also
replace the lwm2m_send_message() call with a direct call of
net_app_send_pkt(). This avoids a second processing of the pending
packets and keeps the ref/unref flow cleaner.

During the CoAP API change, the way packets were ref'd and then
unref'd in order to stop the packet sending functions from releasing
the net_pkts was changed and never updated in the LwM2M library.
Let's use coap_pending_cycle() and coap_pending_clear() to do the
ref/unref the same way as the coap-client samples in order to

The meaning of this address type is the same as NET_ADDR_MANUAL,
but with a provision that DHCP can override such an address.
It's intended for the usecase when there's a default static
configuration for when DHCP is not available, but DHCP should
override it.
Before going to add another address type, there was an attempt
to repurpose TENTATIVE address state, but it doesn't work as
expected, as indeed, all existing address types/states already
have clearly semantics, and it makes sense to just another
address type to avoid confusion and unexpected behavior.

Case #1: If ACK received and our retransmit (i.e. unacked) queue is
empty, it's error. It's incorrect because TCP requires ACK to set for
every packet of established connection. For example, if we didn't
send anything to peer, but it sends us new data, it will reuse the
older ack number. It doesn't acknowledge anything new on our side,
but it's not an error in any way.
Case #2: If retransmit queue is only partially acknowledged, it's an
error. Consider that we have 2 packets in the queue, with sequence
numbers (inclusive) 100-199 and 200-399. There's nothing wrong if
we receive ACK with number 200 - it just acknowledges first packet,
we can remove and finish processing. Second packet remains in the
queue to be acknowledged later.

CoAP packet w/ confirmation flag set is required to be retransmitted
before it got the ACK message from the peer.
However, the packet is usally unreference once it's sent to the network.
Although we set the timeout as no wait when calling function
net_app_send_pkt(), it's still possible that the packet is unreferenced
before we got a chance to increase the packet reference by calling
coap_pending_cycle().
Usually, the IP stack will generate an ARP packet first and then send
out the packet. However, this is not the case when the remote is a
loopback address.
As issue #5101 described, when asking client to perform a firmware pull
on URL "coap://127.0.0.1:7783/large". The packet will be unreferenced
immediately after calling net_app_send_pkt(). Which then result in
client hang.
The solution to the issue is to increase the reference count on the
sending packet and decrease it after the process is finished.

Right now in FIN_WAIT1 state, if we receive FIN+ACK message, then
tcp state changed to FIN_WAIT2 on ACK flag and immediately on FIN
flag state changed to TIME_WAIT. Then final ACK is prepared and sent
(in queue at-least) to peer. Again immediately state changed to
TCP_CLOSED, where context is freed. net_context_put frees context
and releases tcp connection. Final ACK packet which is in queue
is dropped.
As a side effect of freed ACK packet, peer device keep on sending
FIN+ACK messages (that's why we see a lot of "TCP spurious
retransimission" messages in wireshark). As a result
of context free (respective connection handler also removed), we see
lot of packets dropped at connection input handler and replying with
ICMP error messages (destination unreachable).
To fix this issue, timewait timer support is required. When tcp
connection state changed to TIMEWAIT state, it should wait until
TIMEWAIT_TIMETOUT before changing state to TCP_CLOSED. It's
appropriate to close the tcp connection after timewait timer expiry.
Note: Right now timeout value is constant (250ms). But it should
be 2 * MSL (Maximum segment lifetime).

Content-format is used to determine the type of the PUT/POST
request. Therefore, it's incorrect to assign default when the
caller does not include one in the request.
Define LWM2M_FORMAT_NONE=65535 to indicate the format is missing.
The 65000~65535 is reserved for experiments and should be safe for
the purpose. Check content-type at PUT method to setup
write/write-attrs operation accordingly.

According to LwM2M specification 20170208-A, there are two different
discover interfaces supported by the device.
(1) Bootstrap discover (sec 5.2.7.3) (To be implemented)
(2) Device management discover interface (Sec 5.4.2)
- object ID is required (i.e. root directory discover is not allowed)
- attributes should be responded accordingly when implemented
This patch correct the behavior according to the spec and summarized
as follow
(1) Still support CoAP ".well-known/core" but change to report only
first level of the URI.
(2) Respond to caller only when object ID is provided unless it's
bootstrap discover

"""
Before sending a Neighbor Solicitation, an interface MUST join the
all-nodes multicast address and the solicited-node multicast address
of the tentative address.
"""
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
solicited-node group from net_if_ipv6_addr_rm(). In particular, we
leave it if DAD fails (as that function is called in this case).

When the controller is connecting to multiple connectable

If relaying is not supported, or disabled, the Relay Transmit state
will normally be 0, which is not what we want to use when proxying out
packets from GATT clients. The bt_mesh_net_relay() function is also
used for sending out locally originated packets, in which case the
Relay Retransmit state is also the wrong one to use (the Network
Transmit state should be used instead).
This patch makes sure we only use the Relay Retransmit state for
packets originating from the advertising bearer, and for all other
packets use the Network Transmit state.

The bt_mesh_net_relay() function was missing several important checks
for whether a PDU should be relayed or not. In particular, it would
relay a packet from adv to adv even if the Relay state was set to

also relay packets to the GATT Proxy bearer if the Relay state was set
to enabled but GATT Proxy was set to disabled. This patch addresses
both of these issues.

Section 3.4.5.2 in the Mesh Profile Specification (1.0) states:
"The output filter of the interface connected to advertising or GATT
bearers shall drop all messages with TTL value set to 1."
Also: https://www.bluetooth.org/errata/errata_view.cfm?errata_id=9811
Note that this is specifically 1 and not 0, since e.g. Friend PDUs
always go out with TTL 0.
Another noteworthy thing is that the way this has to be implemented is
slightly contrary to how it's presented in the specification (both in
the text as well as the Message processing flow diagram in section
3.11. If this was implemented following the spec to its word, then any
PDU received over GATT or Advertising with TTL 2 would never be
relayed (since the TTL would be 1 when the PDU gets rerouted back to
the bearer). This would be both counterintuitive to the intended
purpose of the TTL, and would also be contrary to the test
specification (see Test Procedure step 1 in MESH/NODE/RLY/BV-01-C).

There were several issues with the code:
- queue_size wasn't properly kept up to date, leading to erroneous
buffer discarding logic.
- Poll timeout when there were buffers in the Friend Queue didn't
work because we didn't track if there'd been a preceding request
for messages or not (hence the added pending_req variable).
- We would overwrite the recv_delay timer if there was another
request while the previous one was still sending (a likely scenario
if we send out multiple advertising events per packet).
- We weren't canceling the sending of a buffer if the Friendship was
