[rbldnsd] Dairiki's v6 version

[Andreas Schulze]

Hi,

I compiled https://github.com/dairiki/rbldnsd/tarball/ipv6/rbldnsd.tar.gz
I use an autobuildsystem to compile for SuSE Enterprise Server 9,10 and 11 and
for the latest OpenSuSE snapshot (OpenSuSE_Factory)

Success for sles9/10/11 but very restrictive compiler setting force warnings to be errors on OpenSuSE_Factory:

+ cd dairiki-rbldnsd-f5f7b68
+ ./configure --enable-ipv6 --enable-stats --disable-master-dump --disable-zlib --disable-dso
configure: rbldnsd... 0.996b+ipv6 (12 Mar 2013)
