a09072c93d gnrc_ipv6_nib: add address from netif to address validation timer 
The `addr` parameter of the NIB's `_handle_dad()` function can come
from anywhere (e.g. in the fallback to classic SLAAC the destination
address of the IP header is used), so putting that pointer in a timer
is not a good idea. Instead we use the version of the address that is
stored within the interface.

731ef19970 gnrc_ipv6_ext: fix packet snip type 
The `pkt->type` of an extension header should be
`GNRC_NETTYPE_IPV6_EXT` so it can be parsed properly as an extension
after building.

2534cfb3fa gnrc_sixlowpan_frag: Initial import of a fragment size hint feature 
This allows for sending of fragments smaller than the restrictions set
by the link-layer PDU. E.g. to put some slack for IPHC into the first
fragment (see https://tools.ietf.org/html/draft-ietf-6lo-fragment-recovery-02#section-4.1).

a3061ab2cc gnrc_sixlowpan_frag: expose fragment interval type 
For the [VRB] I also need to track which the intervals of the fragments
already received (mostly for finding out when I am able to get rid of a
VRB entry, see [this conversation][VRB entry removal]), so to be able to
incorporate it into the common type for both reassembly buffer and VRB I
need to expose that type first.

gnrc_ipv6_ext: don't read from `pkt->data` after `_demux()`

ea1708b402 gnrc_ipv6_ext: don't read from pkt->data after _demux() 
`_demux()` might change `pkt->data` in all kind of ways (moving it due
to `gnrc_pktbuf_mark()`, though unlikely; releasing it, because e.g. it
starts with a fragment header that marks a fragmented packet containing
only one fragment, etc.) so accessing the pointer *after* calling
`_demux()` is somewhat playing with fire. This change avoids this by
storing the value of `ext_hdr->nh` (all we are interested in here) in a
temporary variable that then is used to set the out-parameter `nh`.

`protnum` needs to be unchanged before the call to `_demux()` as it was
set by the previous iteration and determines what extension header
actually is handled.

5732e9bd88 gnrc_ipv6_nib: don't autoconfig IPv6 address without L2 addr 
If the interface's link-layer doesn't use link-layer addresses it
obviously doesn't make sense to auto-configure an IPv6 address from it.
Moreover, I think the address `fe80::` is actual illegal, but I
couldn't find any references for it.

b970d00064 gnrc_ipv6_nib: check if pkt is NULL on error 
According to the documentation of `gnrc_ipv6_nib_get_next_hop_l2addr()`
`pkt` may be `NULL`. However, whenever that function sends an error
message (the methods for that require `orig_pkt` not to be NULL) `pkt`
is not checked, which may lead to failed assertions.

3582dedd4e gnrc_sixlowpan_iphc: check ptr != NULL in compressible check 
Not only does this leave open a risk to crash the node for the check
in `_compressible()` but also is the `tmp` check below getting confused
when `ptr` is `NULL`, since `gnrc_pktbuf_start_write()` returns `NULL`
in that case.
