8f763535ac gnrc_netif: centralize S/TLLAO length to address length function 
The function to infer the link-layer address length from the length of
a S/TLLAO is very dependent on the IPv6 over X specification and thus
should be grouped with the other IP over X functions.

2a6354b07d asymcute: check for minimum packet length early 
Without this patch _len_get reads one byte beyond the con->rxbuf
if the incoming packet consists only of the byte 0x01.

7ae90564d9 gnrc_netif: make _get_iid() just wrapper around _iid_from_addr() 
This way the IID generation gets much simplified and code duplication
is avoided since it removes GNRC's requirement for NETOPT_IPV6_IID.

still should avoid using recursions in general (also to be able to
statically analyze stack usage). This unrolls the recursion.

1f71b30bc2 gnrc_ipv6_nib: fix RA reception for non-6LN interfaces 
When having a non-6LN interface and a 6LN interface (e.g. on a border
router) the assertion can hit when a Router Advertisement is received.
This makes the check an `if` statement rather than an assertion, to
account for that case.

9e3cdebae1 gnrc_sixlowpan_frag: check if own message queue is full 
When issueing the sending of the next fragment the current version of
`gnrc_sixlowpan_frag` doesn't check if the queue is full. This leads to
leakage of the packet buffer, since when it is full, the package never
gets released.

This change adds a checks and error exits in case the queue is full.

so it can be made private. It was only made public so it can be used

02a7bc252a gnrc_ipv6: move ipv6_ext iteration out of ext_demux() 
Since with #10233 we now assume IPv6 packets always to not be
pre-parsed, we can iterate over the extension headers by gradually
"eating" them away. This allows us to move the iteration over them
out of `gnrc_ipv6_ext_demux()` and into `gnrc_ipv6_demux()`.

By moving the iteration over all extension headers out of
`gnrc_ipv6_ext_demux()` we also can

1. simplify the extension header handling a lot, as it now
   just a loop inside `gnrc_ipv6_demux()`,
2. remove the recursion to `gnrc_ipv6_demux()` within
   `gnrc_ipv6_ext_demux()`.

3fde0ef8f8 gnrc_ipv6: remove special handling for encapsulated IPv6 headers 
Since the packet is now guaranteed to be preparsed, the currently
handled IPv6 header will always be in the first snip. Because of this
the packet parser can't get confused anymore which IPv6 header is the
one to be handled so we don't need to remove the more outer ones.
Because of this we can just use the normal packet dispatching (which is
already used by other `GNRC_NETTYPE_*`-known protocol numbers such as
UDP).

This also reverts d54ac38f84.

b530c1bb94 gnrc_ipv6_ext: use send for forwarding with RH 
Though this change might seem more complicated, it has the benefit, that
after #9484 we don't have to assume that a received packet within IPv6's
receive function can be handed to the function pre-parsed, making that
function far less complicated (will be provided in a future PR).

Also this might give the forwarding via routing header a little
performance boost, as we now don't *receive* the packet first only to
forward it later-on.

cdfe8ad90c gnrc_ndp: make compilable for router without ARSM

possible for a (6Lo) router not to maintain an address resolution state

ce0c46836c gnrc_ipv6_nib: provide interface on packet queueing 
Without this the first packet to a new link-local address will not be
delivered in non-6Lo environments, since the interface is not provided.
With this change, if an internet was provided to the address resolver it
will be stored within an allocated `gnrc_netif_hdr_t`.

At this point [IPv6 already striped](netif strip) the packet of its
netif header, so there is no risk that there will be to, in case it was
provided and the `netif` came from its existence.

160ccbcf7e gnrc_ipv6: don't recurse into receive for encapsulated IPv6 
`_decapsulate()` is called by callees of `_receive()` so the call to

Using `gnrc_netapi` instead removes that and provides the added benefit
that other subscribers to IPv6 are also informed.

235661668d gnrc_ipv6_nib: always configure 802.15.4 long address 
Our `gnrc_minimal` example configures the link-local address from the
IEEE 802.15.4 short address since it does not include 6Lo-ND.
This causes the application to be incompatible with our other GNRC
application that do include 6Lo-ND, since it [assumes][1] the link-local
address to be based on the EUI-64 for address resolution.

This enforces long addresses (aka EUI-64) for all IEEE 802.15.4 devices
when IPv6 is compiled in so `gnrc_minimal` is compatible again to the
rest.

Fixes #9910

directly accessing the location of the DIS struct.

fd718dfc74 gnrc_udp: assert ports not zero 
UDP port 0 is reserved for system usage, e.g., to tell the OS to
    set a random source port. Hence, neither source nor destination
    port should be 0 when transmitting. This PR adds proper asserts.

f946314837 gnrc_ipv6: refactor to remove superfluous temporary variable 
Since no release in this function is required anyways, we can just use
`payload` to check the return value directly.

cb4f6a96a8 gnrc_ipv6: correctly reset from temporary variable 
While `tmp` in the loop for write-protection for the check-sum
calculation is used to check the return value of
`gnrc_pktbuf_start_write()`, it was never overwriting `payload` causing
the original snip to be used in the following iteration `prev` when
duplicated, and destroying the sanity of `ipv6`.

8f10d65ad5 net/gcoap: Make references to coap_resource_t const in gcoap 
A CoAP resource is a primary object between the application
    and CoAP library.  The Library needs the paths, methods,
    and handlers from it, so that it can call the right handler.
    However, it never needs to change any of them.

    The application also needs the resources.  The application
    may want to declare the resources as const, since it may
    want to store them in flash.

This refactors reception/decoding part of `gnrc_sixlowpan_iphc` to the

d8081453f2 gnrc_ipv6: clean-up and simplify send handling 
This change is a gnrc_ipv6_nib/gnrc_netif(2)-based rework of #7210.

Packet duplication
==================

Its main optimization is that it restructures `gnrc_ipv6` handling of
sent packets so that duplication for write-protection happens at the
latest possible step:

* potential `gnrc_netif` headers added by upper layers are
  write-protected before their removal
* This unifies the duplication of the IPv6 header directly after
  that
* Extension headers in-between the IPv6 header and the payload header
  are duplicated just before the check sum is duplicated

Especially the last point allows for only handing a single packet snip
to all lower functions instead of an already searched IPv6 header
(which now is always the first until it is handed to the interface) +
payload header.

Further clean-ups
=================
* Next-hop link-layer address determination was moved to the
  `_send_unicast` function, greatly simplifying the unicast case in the
  `_send` function
* Code for loopback case was added to a new function `_send_to_self`
* Removed some code duplication

8721d0b0a2 gnrc_sixlowpan_frag: add page context to reassembly buffer 
While refactoring IPHC I noticed that the page actually can already be
used for fragmentation: Given @cgundogan's work on [ICN LoWPAN] we can
already assume, that the page context may (among other thing) determine
the type of the reassembled packet. This PR provides the basis for
that.
