Enable LRO for TCP per default in the network drivers.

Large Receive Offload allows to receive aggregated packets larger
than the MTU.  Receiving TCP streams becomes much faster.  As the
network hardware is not aware whether a packet is received locally
or to be forwarded, everything is aggregated.  In case of forwarding
it is split on output to packets not larger than the original
packets.  So path MTU discovery should still work.  If the outgoing
interface supports TSO, the packet is chopped in hardware by TCP
Segmentation Offload.

Currently only ix(4) and lo(4) devices support LRO, and ix(4) is
limited to IPv4 and hardware newer than the old 82598 model.  If
the interface is added to a tpmr(4), bridge(4) or veb(4), LRO is
automatically disabled.  All ix(4) devices support outgoing TSO for
IPv4 and IPv6.  Enabling LRO on lo(4) automatically enables TSO and
TCP packets larger than the MTU pass the loopback interface.

LRO can be turned off per interface with ifconfig -tcplro.

Validation for local prefixes, both inet and inet6, was scattered
around. To make it even more confusing, vmd was using generic address
parsing logic from prior network daemons. vmd doesn't need to parse
addresses other than when parsing the local prefix settings in
vm.conf and no runtime parsing is needed.

This change merges parsing and validation based on vmd's specific
needs for local prefixes (e.g. reserving enough bits for vm id and
network interface id encoding in an ipv4 address). In addition, it
simplifies the struct from a generic address struct to one focused
on just storing the v4 and v6 prefixes and masks. This cleans up an
unused TAILQ struct member that isn't used by vmd and was leftover
copy-pasta from those prior daemons.
