core/net/ip: Prevent (tiny) buffer overflow in resolv_found()
...
An off-by-one error in resolv_found() could make an strncat() call
overflow by the terminating null byte.
When building with Clang the following warning was shown:
../../../core/net/ip/resolv.c:1458:17: warning: the value of the
size argument in 'strncat' is too large, might lead to a
buffer overflow [-Wstrncat-size]
sizeof(resolv_hostname) - strlen(resolv_hostname));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../../core/net/ip/resolv.c:1458:17: note: change the argument to
be the free space in the destination buffer minus the
terminating null byte
sizeof(resolv_hostname) - strlen(resolv_hostname));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
sizeof(resolv_hostname) - strlen(resolv_hostname) - 1

Re-create a routing table entry if the next hop is changed.
...
The next-hop address did not get updated in the routing table
in case an entry for the destination already existed.
This patch resolves the issue by removing the entry and
having it re-created from scratch.
The issue causes a routing error triggering reconstruction of
the DODAG through version increase.
In case of somewhat frequent downward traffic in not (yet) stabilized DODAG
a vicious circle is formed: unstable topology means churn, downward
routing under churn causes reconstruction of DODAG. In this situation
the network does not have chance to stabilize.
We encountered a constant churn caused by this bug
in a network of 50 nodes and a periodic traffic (a packet every 5
seconds) generated at the root.
More info and a PCAP demonstrating the issue can be found here:

collect: making some protocol parameters configurable by COLLECT_CONF_ style defines
...
TTL (which has a rather low default of 15), MAC level retransmissions,
overall number of retransmissions, and the header bits dedicated to these
were all fixed in the collect.h and collect.c, without a simple way to
override them.
Extracted these as COLLECT_CONF_ parameters, keeping defaults as they were
before.

Fixed a severe error in the bugfix: the conditional was reversed. The check must be if the TCP MSS is larger than the BUFSIZE and not the other way around.

Make 0 the default link-layer header length, as far as uIP is concerned. Most currently used linke layers (specifically, 802.15.4) has adaptation layers that use separate buffers, so there is no need to reserve space in the uIP buffer.

rdc: duplicate packets: Keep only the last sequence number for each address
...
According to IEEE 802.15.4e (§6.4.3.9), in order to detect duplicate received
MAC-layer frames, only the most recently received frame's sequence number needs
to be stored for each unique device address. Doing so limits the possible false
duplicate packet detections to a single sequence number. This also allows to
keep the last sequence number of more device addresses for the same value of
MAX_SEQNOS.

csma: Initialize sequence number with random value
...
According to IEEE 802.15.4 (§5.1.6.1, §6.4.2), the MAC sequence numbers should
be initialized to random values. This was already the case in
framer-802154.c:create(), but not in csma.c:send_packet(), sometimes causing
false detections of duplicate MAC-layer packets in other devices when a device
was restarted too quickly. This patch decreases the probability of such an
event.

Preliminary support for RPL node types. This change allows a node to be in any of three given types:
...
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.
This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.
