69d9ecc0d9 gnrc_sixlowpan_iphc: refactor reception for #8511 
This refactors reception/decoding part of `gnrc_sixlowpan_iphc` to the
more layered approach modeled in #8511. Since the reception part is
already complicated enough I decided to divide send and receive up into
separate changes.

64fed621d2 gnrc_sixlowpan_frag: Expose functions to finish datagram 
This will be used in the IPHC refactoring to control the reassembly
buffer as a context.

I also adapted the name of `gnrc_sixlowpan_frag_gc_rbuf()` to be in
line with the rest of the newer functions.

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.

254f16e81f gnrc_sixlowpan_frag: add asynchronous rbuf GC 
While the current approach for garbage collection in the 6Lo reassembly
buffer is good for best-effort handling of
*fragmented* packets and nicely RAM saving, it has the problem that
incomplete, huge datagrams can basically DoS a node, if no further
fragmented datagram is received for a while (since the packet buffer is
full and GC is not triggered).

This change adds a asynchronous GC (utilizing the existing
functionality) to the reassembly buffer, so that even if there is no new
fragmented packet received, fragments older than `RBUF_TIMEOUT` will be
removed from the reassembly buffer, freeing up the otherwise wasted
packet buffer space.

68fe6682ff gnrc_sixlowpan_frag: add current_size to exposed struct 
Since IPHC also manipulates the total number of bytes of a received
datagram (by decompressing it), this also needs to be exposed. I guess
I was too focused on introducing a *generic* packet buffer for a future
virtual reassembly buffer (where it isn't needed, but so isn't `pkt` to
be honest), that I totally forgot about it in #9352.

a2eb3c7f15 gnrc_sixlowpan_frag: adapt for #8511 
This refactors the `gnrc_sixlowpan_frag` module for the API proposed
in #8511.

The `ctx` for `gnrc_sixlowpan_frag_send()` is required to be a
`gnrc_sixlowpan_msg_frag_t` object, so IPHC can later on use it to
provide the *original* datagram size (otherwise, we would need to adapt
the API just for that, which seems to me as convoluted as this
proposal).

I also provide an expose function with a future possibility to provide
more than just one `gnrc_sixlowpan_msg_frag_t` object later on (plus
having cleaner module separation in general).

2c9ee62eb0 gnrc_sixlowpan: fix order of gnrc_sixlowpan_msg_frag_t 
While working on #9352 I noticed that the order of members in the
`gnrc_sixlowpan_msg_frag_t` struct costs us 4 bytes in RAM due to byte
alignment. This PR fixes the order of members, so they are the most
packed.

86cbde2db5 gnrc_sixlowpan_frag: expose (parts of) reassembly buffer 
This exposes the parts of the reassembly buffer to be usable as context
as proposed in #8511.

I only exposed *parts of* for two reasons:

1. I don't need to expose further types (like `rbuf_int_t`), that are
   not of interest outside of fragmentation.
2. This allows for an easy future extension for the virtual reassembly
   buffer as proposed in [[1]].

This makes this change a little bit more involved, because instead of
just renaming the type, I also need to add the usage of the `super`
member, but I think in the end this little preparation work will be
beneficial in the future.

faa47a0e03 gnrc_sixlowpan_iphc: Fixed encoding when COMP=0 
Summary:

Even ehen COMP is cleared, the algorithm always elides part of the address when a matching
context is found.

This behviour occurs because in the line

  if ((src_ctx != NULL) || ipv6_addr_is_link_local(&(ipv6_hdr->src)))

the COMP bit is not tested.

This patch fixes the problem by setting [src|dst]_ctx to NULL if the
context must not be used.

5cb904b57e gnrc_sixlowpan_nd: fixed crash on gnrc_sixlowpan_nd_next_hop_l2addr. 
When `gnrc_ndp_node_next_hop_l2addr` cannot resolve L2 address, it creates a
temporary neighbor cache entry with interface `KERNEL_PID_UNDEF` (unless the
interface is already known) to send a neighbor solicitation. When another packet
directed to the same address is going to sent before receiving a neighbor
advertisement, `gnrc_sixlowpan_nd_next_hop_l2addr` gets the temporary neighbor
cache entry and calls `gnrc_ipv6_netif_get` with `KERNEL_PID_UNDEF`, resulting
get a `NULL`. We must check `NULL` before dereference it.

FYI, both `gnrc_ndp_node_next_hop_l2addr` and
`gnrc_sixlowpan_nd_next_hop_l2addr` are enabled when
`gnrc_sixlowpan_border_router_default` module is enabled with `GNRC_NETIF_NUMOF`
is greater than 1:

gnrc_sixlowpan_border_router_default
→ gnrc_ipv6_router_default
→ gnrc_ndp_router (if GNRC_NETIF_NUMOF > 1)
→ gnrc_ndp_node
→ gnrc_ndp_node_next_hop_l2addr is called from _next_hop_l2addr

gnrc_sixlowpan_border_router_default

→ gnrc_sixlowpan_nd_router
→ gnrc_sixlowpan_nd
→ gnrc_sixlowpan_nd_next_hop_l2addr is called from _next_hop_l2addr
