c32f1076f6 gnrc_icmpv6_error: consider originator's destination address correctly 
While 485dbd1fda (from #12175) was right
in assuming that the for most ICMPv6 error messages the originating
packet's destination address must not be a multicast, this is not the
case for _all_ ICMPv6 error messages (see [RFC 4443], section 2.4(e.3)).
Additionally, 485dbd1fda removed the
check for the source address ([RFC 4443], section 2.4(e.6)), which this
PR re-adds.

485dbd1fda [gnrc_icmpv6_error] Fixed multicast detection 
before this commit the src address was checked for multicast, but the dst address should be checked. Therefore udp multicast packets would be flooded back to the src as ICMPv6 error, as not all nodes had a UDP receiver registered.

c88838f391 gnrc_icmpv6_echo: avoid crashing when pktbuf full 
Once the packet buffer is full on heavy network load, gnrc_netif_hdr_build may return NULL. In that case, the following unchecked access to hdr->data leads to a crash.

ef1132384a gnrc_icmpv6_error: check IPv6 header before starting to build 
Check for:

 - if it exists (critical error condition -- non-IPv6 headers should
   not trigger these functions) => assert
 - if it has a multicast source (that shouldn't really happen but
   people might try weird stuff ;-)
 - if it has an unspecified source (can't determine receiver of error
   message => don't send it, don't build it)

12fad002da gnrc_icmpv6_echo: fix ping for loopback 
At the moment ping is crashing if one pings the loopback address.
This was caused in #8214 when we moved interfaces from `kernel_pid_t`
ID to pointer-based handling, since loopback doesn't evaluate to such
an interface.
