BUG/MEDIUM: balance source did not properly hash IPv6 addresses

The hash of IPv6 addresses was not properly aligned and resulted in the
last quarter of the address not being hashed. In practice, this is rarely
detected since MAC addresses are used in the second half. But this becomes
very visible with IPv6-mapped IPv4 addresses such as ::FFFF:1.2.3.4 where
the IPv4 part is never hashed.

This bug has been there forever, since introduction of "balance source" in
v1.2.11. The fix must then be backported to all stable versions.

Thanks to Alex Markham for reporting this issue to the list !
