f544890056 gnrc/nib: don't add routers from WPAN as default router for 6LBR 
This avoids a race condition where the default router slots for the 6LBR
are used up by router advertisements from the 6Lo network that arrived
before router advertisements from the upstream network.

The border router should ignore 'default routers' from the 6Lo network as
it consitutes the uplink for that network.

2139b51cb5 gnrc/nib: only enable RTR_ADV on RA if MULTIHOP_P6C is enabled 
If multihop distribution is not done using RA messages, then the
routers follow [RFC4861], which states that they merely do some
consistency checks; in this case, nothing in Section 8.1 applies.

15f210e4e4 gnrc/nib: don't advertise /128 prefix for auto-configuration 
A single IP address will be added as a /128 prefix.
It makes sense to advertise it, as neighbors can then know that
the address/prefix is on-link.

It does however not make sense to advertise the prefix as suitable
for auto-configuration.

452500b3eb gnrc_ipv6_nib: consider largest prefix match when deciding if host on-link 
If the fib contains a route to a subnet via another host, it can not
be on-link.

Consider fib entries when deciding whether an address is on-link.
If a route via another host is a stronger match than an on-link
prefix, the address must be off-link.

71ae768e56 net/gnrc/ipv6/nib: add option to include RIO with final RA 
Sending a RA with ltime = 0 does not get us added to the default router
list, but the options (and therefore the RIO) are still parsed.

This even appears to work with Linux as a receiver.

62308d200c gnrc_ipv6_nib: don't stop sending router solicitations on last RA 
When the default router was removed or could not be added, `dr` will
be NULL.

In this case, don't cease sending router solicitations - we still don't
have a default router.

11e9b7c08f gnrc_ipv6_nib: only consider NC in gnrc_ipv6_nib_get_next_hop_l2addr() 
Consider the following: A node tries to forward a packet to another
host for which it does not know the route yet. It assumes it to be
on-link and starts a neighbor solicitation, putting the node address
in the destinatio cache.

Later the route is known (via a second hop) but the host is still in
the NIB.

The result is that gnrc_ipv6_nib_get_next_hop_l2addr() ends up in the
"nib: %s is in NC or on-link, start address resolution" case and does
not attempt to resolve the route.

This results in the host remaining unreachable even though now a route
is present.
