6af92ee113 gnrc/nib: fix _idx_dsts() calculation 
Using pointer difference already gives us the number of elements of
size of what the pointer is pointing to.
Dividing by size will lead to the wrong (always 0) result.

gnrc/ipv6: Configure queue size with exponent 
This changes the configuration macro to be the exponent of 2^n, as the
message queue size needs to be always power of 2.

3974a04623 gnrc/nib: add NIB event bus 
Add a message bus where threads can listen for nib events.

Currently only the GNRC_IPV6_NIB_EVENT_ADDR_VALID event is
implemented which informs subscribers that an address got
valid.

gnrc_ipv6_nib: only add prefix of same interface to ABR 
It doesn't make sense for an Authoritative Border Router to manage a
prefix that does not belong to the border router's downstream
interface.

gnrc_ipv6_nib: 6ln: use interface-specific DR for address registration 
With multiple 6LoWPAN interfaces the router for the given interface
—the one the triggering RA came over—should be used to register the
address with.

gnrc_ipv6_nib: only route to prefix list entry if on-link 
In 06aa65e1ba (#10627) a new behavior was
introduced in IPv6 route resolution to try address resolution only at
interfaces that have the prefix of the address to be resolved configured
in the prefix list. This however only makes sense, if the prefix
configured is [on-link], otherwise there is small likelihood of the
address to be resolved being on that link.

For the error case presented for 06aa65e (circular routing at the border
router) this made sense, however within a 6LoWPAN, due to the prefix
being valid for the entire mesh, this leads to the nodes always trying
classic address resolution for in-network addresses instead of just
routing to the default route.
Classic address resolution however fails, as 6LoWPAN hosts typically
[don't join the solicited-node multicast address of their unicast
addresses][6LN-iface-init], resulting in in-network addresses not being
reachable.

As such, to prevent both error cases

- the fallback to address resolution by prefix list must only be used
  when the prefix is on-link,
- the prefix configured by DHCPv6/UHCP at the 6LoWPAN border router
  must be configured as on-link, but
- the prefix must not be advertised as on-link within the 6LoWPAN to
  still be [in line with RFC 6775][RFC-6775-forbidden]

With this change these cases are covered.

gnrc_ipv6_nib: don't ignore PL for route 
When pinging to a prefix for which there is a prefix list entry on the
node (so no next hop) but a default route, a packet to a non-existent
address under that prefix results in the packet being forwarded to the
default route instead. This fixes it, so the node tries address
resolution on the interface the prefix list entry is associated to.
