aa953a40ea gnrc_ipv6_nib: fix preparation of delayed NA 
Currently the constructed NA for a delayed NA case is neither used nor
released nor does it get an IPv6 header to be used properly. This fixes
that case.

660440c1c2 gnrc_ipv6_nib/nc: remove from _next_removable on remove 
The `_next_removable` list manages the cache-out of the neighbor cache.
However, when a neighbor cache entry is removed, it is not removed
from that list, which may lead to a segmentation fault when that list is
accessed, since the whole entry (including its list pointer) is zeroed
after removal.

With this change the entry is removed from that list accordingly before
the zeroing happens.

43c2c728c9 gnrc_sixlowpan_iphc: fix _compressible() 
When either `gnrc_sixlowpan_iphc_nhc` or `gnrc_udp` is not compiled
in `_compressible()` never returns `true`. This causes the
`dispatch` snip in `gnrc_sixlowpan_iphc_send()` to be of length 0,
meaning `dispatch->data` is `NULL`, causing possible crashes when
trying to send IPv6 packets over 6LoWPAN without NHC or UDP.

983b60dbd4 gnrc_rpl: do not assert netif on auto-init 
`gnrc_networking` is unusable when compiled for boards that do not have
any network devices on-board due to an assertion in RPL's auto-init. I
think this is pretty harsh. A friendly info message is enough, as it
might not even be an error. Also, if one expects RPL to work without
network interfaces they are a fool ;-).

7d9ef9f78c gnrc_sixlowpan_frag/rbuf: add offset assertion to rbuf_add() 
`gnrc_sixlowpan_frag` internally derives the offset value directly
from the fragment header, so for normal usage within GNRC this
assertion is redundant, but to make the tests of `rbuf_add` 100%

b0beba3c1c gnrc_ipv6_nib: release when not queuable on AR 
When a new queue entry is tried to be allocated for a neighbor who's
address is currently tried to be resolved there was no error case
before. The packet that was tried to be put in the queue was thus not

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

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.

764ed8c300 gnrc_ipv6: make next-header demuxer private 
Since the recursion into `gnrc_ipv6_demux()` was removed in
`gnrc_ipv6_ext`, `gnrc_ipv6.c` is the only user of this function,
so it can be made private. It was only made public so it can be used
from `gnrc_ipv6_ext`.

f671a87fe2 gnrc_ipv6_ext: remove unnecessary pkt write-protection 
As `pkt` isn't pre-parsed the write-protection of *the whole* packet

receive routine of IPv6.

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.

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.

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

gnrc_rpl: Pass options length to msg validator 
Currently the length of the full ICMPv6 packet is passed to the
validator function causing validation failures on valid packets. This
fixes that by passing the length of remaining RPL options of the packet.

gnrc_rpl: fix zeroing of RPL DIS fields 
The code originally assumed that the location of DIS struct is directly
after the ICMPv6 struct. This is not necessarily true when both structs
are individually allocated by pktbuf. This commit fixes this issue by
directly accessing the location of the DIS struct.

4f87883ab8 gnrc_ipv6_nib: fallback to SLAAC if ARO is ignored by upstream 
Linux doesn't have ARO support at the moment so this is a workaround to
try to speak 6Lo-ND while still being able to do DAD with a border
router that doesn't.
