Subject: [PATCH] dnsdist: add missing ComboAddress functions to Lua bindings

iputils.hh implements toStringReversed & toStringNoInterface, but they
were not exposed to Lua:

 > ca4=newCA("192.168.100.200")
 > ca4:toStringReversed()
 200.100.168.192
 > ca6=newCA("fd39:8628:558:0:62b5:8dff:fe1e:d8a8")
 > ca6:toStringReversed()
 8.a.8.d.e.1.e.f.f.f.d.8.5.b.2.6.0.0.0.0.8.5.5.0.8.2.6.8.9.3.d.f
 > ca6if=newCA("fe80::1ff:fe23:4567:890a%eth0")
 > ca6if:toStringNoInterface()
 fe80::1ff:fe23:4567:890a
