netfilter: nft_nat: add netmap support
This patch allows you to NAT the network address prefix onto another
network address prefix, a.k.a. netmapping.
Userspace must specify the NF_NAT_RANGE_NETMAP flag and the prefix
address through the NFTA_NAT_REG_ADDR_MIN and NFTA_NAT_REG_ADDR_MAX
netlink attributes.
