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.

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.

net/sixlowpan: Fixed calculation of fragment size 
Fragment size calculation previously failed for devices that are able to
transmit bigger layer 2 PDUs that 802.15.4 devices. This commit fixes the issue.

43c2c728c9 gnrc_sixlowpan_iphc: fix _compressible() 
When either `gnrc_sixlowpan_iphc_nhc` or `gnrc_udp` is not compiled
in `_compressible()` never returns `true`. This causes the
`dispatch` snip in `gnrc_sixlowpan_iphc_send()` to be of length 0,
meaning `dispatch->data` is `NULL`, causing possible crashes when
trying to send IPv6 packets over 6LoWPAN without NHC or UDP.

7d9ef9f78c gnrc_sixlowpan_frag/rbuf: add offset assertion to rbuf_add() 
`gnrc_sixlowpan_frag` internally derives the offset value directly
from the fragment header, so for normal usage within GNRC this
assertion is redundant, but to make the tests of `rbuf_add` 100%
water-tide I added it.

879321d68a gnrc_sixlowpan: stop type-finding loop when type is found

In #10851 this lead to a crash of the tests, when the dependency of
`gnrc_sixlowpan` to `gnrc_ipv6` was removed.

7452f48c26 gnrc_sixlowpan_frag: unroll recursion 
While the recursion in `gnrc_sixlowpan_frag` shouldn't be infinite we
still should avoid using recursions in general (also to be able to
statically analyze stack usage). This unrolls the recursion.

9e3cdebae1 gnrc_sixlowpan_frag: check if own message queue is full 
When issueing the sending of the next fragment the current version of
`gnrc_sixlowpan_frag` doesn't check if the queue is full. This leads to
leakage of the packet buffer, since when it is full, the package never
gets released.

This change adds a checks and error exits in case the queue is full.
