gnrc_sixlowpan_frag_vrb: append intervals of given base if entry exists
Otherwise the list in `base->ints` will get lost.

gnrc_sixlowpan_frag_stats: actualize pseudo-module
Having the definitions sit in the `net/gnrc/sixlowpan/frag.h` header
does not make much sense, when using Selective Fragment Forwarding
(and the fragmentation buffer already includes a
`net/gnrc/sixlowpan/frag/stats.h` header), so they are moved to their
own header. Since with this change it makes more sense to have the
statistics stored in their own sub-module, the pseudo-module is also
actualized.

8c3dc66ad8 gnrc_sixlowpan_frag: factor-out and rename fragmentation buffer
The name `fragment_msg` or `frag_msg`/`msg_frag` always to me was a bit
misplaced, as it basically implements an asynchronous fragmentation
buffer and doesn't necessarily have anything to do with messages.
This change

1. changes the name to `fb` (for fragmentation buffer)
2. factors its code out to its own sub-module so it can be re-used by
   other 6LoWPAN fragmentation schemes like [Selective Fragment
   Recovery]

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.
