e4d95c568b gnrc_sixlowpan_frag_vrb: set src_len to 0 on remove 
45f7966 made the `src_len` field the "emptiness signifier" for the VRB.
However, when `gnrc_sixlowpan_frag` is compiled in, the remove function
`gnrc_sixlowpan_frag_vrb_rm()` does not set the `src_len` to zero,
resulting in already deleted entry to be recognized as non-empty.

40138fdce8 gnrc_sixlowpan_frag_rb: allow for deletion timer after completion 
This allows to set a timer between the completion of a datagram in the
reassembly buffer and the deletion of the corresponding reassembly
buffer entry. This allows to ignore potentially late incoming link-layer
duplicates of fragments of the datagram that then will have the
reassembly buffer entry be blocked.

This was noted in this [discussion] for classic 6LoWPAN reassembly (and
minimal fragment forwarding) and is recommended in the current
[selective fragment recovery draft][SFR draft].

da74936020 gnrc_sixlowpan_frag: initial import of SRF parameters 
This imports the protocol parameters for Selective Fragment Recovery
(SFR). For the values I took some educated guesses based on my
experience with previous experimentation with fragment forwarding.

The defines currently are based on [draft v7].

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]

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.

need to expose that type first.
