When adding a route with "mtu lock <mtu>" path MTU discovery (PMTUD)
will not be tried and packets will be sent without DF bit set. Upon
receiving an ICMP needs frag due to PMTUD, the kernel will not install a
cached route and lower the MTU.

Commit ec93726159 ("Adds strings translation methods") broke non-Linux
builds by relying on unix constants that are only declared on the linux
platform in the upstream x/sys/unix package.
Other platforms report undefined variables, such as the following:
$ GOOS=darwin go build .
# github.com/vishvananda/netlink
./route.go:17:7: undefined: SCOPE_UNIVERSE
./route.go:19:7: undefined: SCOPE_SITE
./route.go:21:7: undefined: SCOPE_LINK
./route.go:23:7: undefined: SCOPE_HOST
./route.go:25:7: undefined: SCOPE_NOWHERE
./route.go:55:7: undefined: unix.RTPROT_BABEL
./route.go:57:7: undefined: unix.RTPROT_BGP
./route.go:59:7: undefined: unix.RTPROT_BIRD
./route.go:61:7: undefined: unix.RTPROT_BOOT
./route.go:63:7: undefined: unix.RTPROT_DHCP
./route.go:63:7: too many errors
Move the platform-specific implementations to platform-specific files
and add stubs to satisfy other platforms.

There are lots of route metrics to be added, such as rto_min,
quick_ack and so on, and these metrics are useful for users to
tune network performance, so we add all these metrics.

This is a `net.IP` and therefore, we should use `%s`. Using `%d` gives
something like this:
Gw: [0 0 0 0 0 0 0 0 0 0 255 255 192 168 24 2]
After this fix, we get:
Gw: 192.168.24.2
$ ip -M route add 100 dev eth0
$ ip -M route add 100 as to 200/300 dev eth0
$ ip -M route add 100 nexthop dev eth0 as to 200 \
nexthop dev eth1 as to 300
$ ip route add 10.10.0.0/24 encap mpls 200/300 dev eth0
$ ip route add 10.0.0.0/24 nexthop encap mpls 200 dev eth0 \
nexthop encap mpls 300 dev eth1

Having object composition causes both client and library to
do potentially unecessary work to retrieve Link attributes
when only index is often sufficient.
