f8d75d7add gnrc_sixlowpan_frag_rb: behavioral change to add() 
Rather than dispatching the packet automatically once it is complete,
`gnrc_sixlowpan_frag_rb_add()` now only returns success, and leaves it
to the caller to dispatch the packet.

b5b52c74e8 gnrc_ipv6: only discard invalid source when assigned to interface 
While it is correct to not use an invalid address as a source address,
it is incorrect to assume that addresses not assigned to the interface
(`idx == -1` in the respective piece of code) are invalid: Other than
classic forwarding via a FIB, forwarded packets utilizing a IPv6
routing header will pass this check, like any other packet sent by this
node. The source address for these is not on the given node, so e.g.
source routing is not possible at the moment.

a279228663 gnrc_rpl_srh: don't send error message on multicast error 
A node is not supposed to send an ICMPv6 error message when the
destination or one of the addresses in the source route is multicast
but is supposed to be silently discarded (see [RFC4443] and [RFC6554]).
If we leave the `err_ptr` unset, the [node will not send an error
message][err_ptr set].

[RFC 6554]: https://tools.ietf.org/html/rfc6554#section-4.2

095e966b73 gnrc_ipv6_ext_frag: fix release on rbuf creation for n-th fragment 
The IPv6 (extension) headers of the first fragment received are re-used
for the reassembled packet, so when receiving a subsequent packet we
need to distinguish, if we just want to release the payload or all of
the packet after the packet data was added to the reassembly buffer.

f6686e92f1 gnrc_sixlowpan_frag_vrb: add gnrc_sixlowpan_frag_vrb_from_route() 
This adds a new VRB function that receives a header with forwarding
information and creates a VRB entry from it. Currently, only IPv6 is
supported.

45f7966364 gnrc_sixlowpan_frag_vrb: fix for draft update 
Due to some changes to the minimal forwarding draft and in preparation
for Selective Fragment Recovery some changes to the VRB API were
needed. Now the index of a VRB entry is only (L2 src, tag) not as
before (L2 src, L2 dst, length, tag).

I know that the current `rbuf_base` causes waste, as all the fields not
used by the new index are effectively not used by the VRB. I'd like to
fix that however in a later change, since that also requires some
modifications of the classic reassembly buffer, and thus would
complicate the review and testing of the change.

Sources for the index change:

e5503d62bf gnrc_tcp: check if option length field is present before accessing it 
TCP options have up to three fields (kind, length, value). The
current code only checks for the presence of the first field. Before
accessing the second field (length) the code must ensure that a length
field is even present.

1ca05f0c08 gnrc_netif_ethernet: fix debug output for received packet 
A received packet is outputted in DEBUG _after_ it was already parsed,
but with a reference to the already parsed header. The result is that
there can be some garbage in the output and the packet is not dumped in
total. As without parsing we do not have access to the header yet, we
use the `gnrc_netif_addr_to_str()` helper function instead of parsing
the destination address by hand.
