This refactors the `gnrc_sixlowpan_frag` module for the API proposed
in #8511.
The `ctx` for `gnrc_sixlowpan_frag_send()` is required to be a
`gnrc_sixlowpan_msg_frag_t` object, so IPHC can later on use it to
provide the *original* datagram size (otherwise, we would need to adapt
the API just for that, which seems to me as convoluted as this
proposal).
I also provide an expose function with a future possibility to provide
more than just one `gnrc_sixlowpan_msg_frag_t` object later on (plus
having cleaner module separation in general).
Add support to do flash/reset/term on an IoT-LAB node.
It also allow running test using 'testrunner'.
Configuration variables are:
* `IOTLAB_NODE` which should be set to your node url
* The full url including site to use from your computer `m3-1.grenoble.iot-lab.info`
* The short url when used on the IoT-LAB frontend `m3-1`
* `IOTLAB_EXP_ID` for your experiment id for flash and reset.
By default it tries to use your currently running experiment if you have only one
* `IOTLAB_USER`: is read from `${HOME}/.iotlabrc` as saved by `iotlab-auth`
* It is expected to have run `iotlab-auth` beforehand.
While working on #9352 I noticed that the order of members in the
`gnrc_sixlowpan_msg_frag_t` struct costs us 4 bytes in RAM due to byte
alignment. This PR fixes the order of members, so they are the most
packed.
This exposes the parts of the reassembly buffer to be usable as context
as proposed in #8511.
I only exposed *parts of* for two reasons:
1. I don't need to expose further types (like `rbuf_int_t`), that are
not of interest outside of fragmentation.
2. This allows for an easy future extension for the virtual reassembly
buffer as proposed in [[1]].
This makes this change a little bit more involved, because instead of
just renaming the type, I also need to add the usage of the `super`
member, but I think in the end this little preparation work will be
beneficial in the future.

The include/crypto path should include 'sys' to be vavil
But all source files are already using '#include "crypto/HEADER.h"' so it does
not need fixing.
In this Makefile, 'CURDIR' is RIOTBASE/pkg/tiny-asn1 directory which does not
exist and not PKGDIRBASE/tiny-asn1.
The correct include directory is set by pkg/tiny-asn1/Makefile.include.
