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
(except the netif-header) comes for free, when this was done in the
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.

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.

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