Currently, we always set the content-format as "plain/text" when
it is unrecognized. This is wrong for it's possible that payload
is actually something else.
For example, we don't support JSON as incoming format right now.
But if I send a PUT request to /1/0/1 (server objectinstance/lifetime
resource) with value 3200 in JSON format: {"e":[{"n":"","v":3200}]}.
The client will still handle the request and respond with changed (2.04)
except the lifetime resource is updated incorrectly due to parsing
error.
Correct the behavior by not setting a default format and respond with
content-format-not-support error code (4.15)

For the native port, when feeding commands from a file or
pipe the prompt reprinting after each command (without echoing)
just confuses the user.

net_pkt_append() has been changed. If payload reached max value
of 'data_len' in net packet, net_pkt_append will not append.
So the caller has to create new packet and append remaining payload.

When a node receives DIO message from peer then node adds peer as
a neighbor (nbr with linklayer address). But when a node receives
DAO message from different peer (chances are peer selected
different route to reach this node), remove peer with previous
link layer address and add as a neighbor with new link layer address
with new route information. Now node can properly route packets to
peer from neighbor table or based on nexthop information from
routing table.

When a node joins in DAG network, it chooses neighbor (node or border
router) as its parent. But if it receives DIO message from another
peer, it can only act as a neighbor, not as a parent. If peer rank
is better than current preferred parent rank then node will select
new peer as it's best parent.

Current default value for NET_RPL_INIT_LINK_METRIC is 2, changing it
to 1.
e.g. NET_RPL_MIN_HOP_RANK_INC is 256 and NET_RPL_MC_ETX_DIVISOR is 256.
Rank calculation for nodes is
rank_increase = CONFIG_NET_RPL_INIT_LINK_METRIC *
NET_RPL_MC_ETX_DIVISOR;
Which gives 768 for first set of child nodes. It would be good if
CONFIG_NET_RPL_INIT_LINK_METRIC value is 1 and nodes ranks will be
245, 512, 768 based on the path they choose.
User can absolutely change their configuration to maintain proper ranks.

During the CoAP API change, slight changes were made the ref / unref

in how we apply the packet refs in retransmit_request() and also

net_app_send_pkt(). This avoids a second processing of the pending
packets and keeps the ref/unref flow cleaner.
