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.

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.

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.

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 ).
