Make gen_subnetv6 return a compressed form IPv6 address/net representation. This removes some issues reported during Ticket #2746 and solve the issue on some cases

Need to rethink this again
Revert "Ticket #2636 Seems ipsec apart IP-IP does not have any after processing for input packets. Make the filter apropriately so the packets are passed correctly through BPF and pfil(9)"

This reverts commit e0f338eb1b02d7bf4920d4682404412e98a3075c.

Actually let xmlrpc construct the url internally from the passed info it is doing same checks

Avoid possible deadlock during voucher xmlrpc sync and correct url generation for xmlrpc
