Contribution description

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.

Testing

To test I used the ping6 and udp {send|server} server command tests/gnrc_udp with different packet sizes and ports (including the NHC UDP compressed range 61616-61631), and also with IPHC (de-)activated with ifconfig 6 -iphc on samr21-xpro. I also tested several compile configurations with the following patch (and commenting out the corresponding iphc/frag lines):

diff --git a/tests/gnrc_udp/Makefile b/tests/gnrc_udp/Makefile
index 9496288..9b594ec 100644

(just resolves the dependency)

Issues/PRs references

Depends on #9482 (merged) and #9483 (merged).

Adapts IPHC reception for #8511.

Also ping @A-Paul. I think this could be interesting regarding GHC.

Note to self: adapt for rename solicited in #9483 (comment), when rebasing.

(since both dependencies are merged this PR is not waiting for another PR anymore)

Rebased again, since the merging of #9485 created a conflict.

Code looks fine and verified that frag/iphc is still working. Tested on the testbed w/ and w/o compiling frag/iphc.

gnrc_ipv6_ext: use send for forwarding with RH
fd3d59d 
Though this change might seem more complicated, it has the benefit, that
after RIOT-OS#9484 we don't have to assume that a received packet within IPv6's
receive function can be handed to the function pre-parsed, making that
function far less complicated (will be provided in a future PR).

Also this might give the forwarding via routing header a little
performance boost, as we now don't *receive* the packet first only to
forward it later-on.
