Add NetVM-facing neighbor entry in NAT namespace
Since AppVMs will have their own NetVM-facing neighbor entries, a user
might (correctly) conclude that NetVMs do not need ARP or NDP enabled.
For this to work with NAT namespaces, they need their own neighbor
entries.

Optimization: use ip -n over ip netns exec
This saves an exec call.

NAT network namespaces need neighbor entries
If we are using a NAT network namespace, it needs its own neighbor
entries.  For consistency, give it the same MAC address as the VM it
connects to.

network: use /32 netmask on internal IPs in NAT providing namespace
Use /32 inside network namespace too. Otherwise inter-VM traffic is
broken - as all VMs seems to be in a single /24 subnet, but in fact are
not.

network: properly handle DNS addresses in vif-qubes-nat.sh
Core3 no longer reuse netvm own IP for primary DNS. At the same time,
disable dropping traffic to netvm itself because it breaks DNS (as one
of blocked things). This allows VM to learn real netvm IP, but:
 - this mechanism is not intended to avoid detection from already
 compromised VM, only about unintentional leaks
 - this can be prevented using vif-qubes-nat.sh on the netvm itself (so
 it will also have hidden its own IP)

network: change vif-route-qubes-nat parameters
Keep "main" IP (the one in xenstore) as the one seen by the netvm, and
pass the "fake" one (the one seen by the VM) as script parameter.
