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.
While browsing through the rendered doc, I found the precondition of
`gnrc_netreg_register()` somewhat lacking. What is a "message queue"?
`gnrc_netreg_entry_t`s have types. Does this apply for all types?
This specifies the requirement more: The calling thread **only** needs
a message queue (also provides a link to `msg_init_queue()` now for
further information), if the provided `gnrc_netreg_entry_t` is of type
`GNRC_NETREG_TYPE_DEFAULT` (i.e. thread-wise IPC).
Fix re-register when using the same token.
Handle edge cases when change token for a resource.
Only set observer and resource on initial registration.
Discuss re-registration in documentation.
With #9209 gCoAP got the ability to re-register and OBSERVE with a new
token, sadly the `observer` variable wasn't set in that fix, so a
re-registration actually led to the deletion of the observer (because it
is still `NULL` when the old registration is overwritten in l. 317)
The macro MODULE_TLSF_MALLOC indicates if tlsf is being used as the system-wide
allocator. MODULE_TLSF only incates if TLSF is present.
PS should check for MODULE_TLSF_MALLOC to decide if heap information should be
displayed.
OutputterPrintHeaderFunction is declared as a function of 1 parameter
but CompilerOutputter_printHeader was defined as taking 2.
It is a mystery why this code compiled before.
