931b179d14 gnrc_sixlowpan_frag: encapsulate msg_send_to_self() 
This makes it easier to access this functionality for test cases e.g.
from the `main` thread.

f6d3290507 gnrc_sixlowpan: don't use PRIx8 
With newlib nano-specs the debug output without this change will be

With this PR this will provide a correct output, e.g.

    6lo: dispatch 0x3f ... is not supported

7d8f6abd45 gnrc_netif: check all required options on initialization 
With `DEVELHELP` activated all required options required by GNRC are
now checked at interface initialization, so that developers of new
link-layer protocols or device drivers notice as soon as possible that
something is missing.

660440c1c2 gnrc_ipv6_nib/nc: remove from _next_removable on remove 
The `_next_removable` list manages the cache-out of the neighbor cache.
However, when a neighbor cache entry is removed, it is not removed
from that list, which may lead to a segmentation fault when that list is
accessed, since the whole entry (including its list pointer) is zeroed
after removal.

With this change the entry is removed from that list accordingly before
the zeroing happens.

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.

983b60dbd4 gnrc_rpl: do not assert netif on auto-init 
`gnrc_networking` is unusable when compiled for boards that do not have
any network devices on-board due to an assertion in RPL's auto-init. I
think this is pretty harsh. A friendly info message is enough, as it
might not even be an error. Also, if one expects RPL to work without
network interfaces they are a fool ;-).

7452f48c26 gnrc_sixlowpan_frag: unroll recursion
