Brad Fitzpatrick 0994a9f7c4 wgengine{,/magicsock}: fix, improve "tailscale ping" to default routes and subnets 
e.g.

$ tailscale ping 1.1.1.1
exit node found but not enabled

$ tailscale ping 10.2.200.2
node "tsbfvlan2" found, but not using its 10.2.200.0/24 route

$ sudo tailscale  up --accept-routes
$ tailscale ping 10.2.200.2
pong from tsbfvlan2 (100.124.196.94) via 10.2.200.34:41641 in 1ms

$ tailscale ping mon.ts.tailscale.com
pong from monitoring (100.88.178.64) via DERP(sfo) in 83ms
pong from monitoring (100.88.178.64) via DERP(sfo) in 21ms
pong from monitoring (100.88.178.64) via [2604:a880:4:d1::37:d001]:41641 in 22ms

This necessarily moves code up from magicsock to wgengine, so we can
look at the actual wireguard config.

Brad Fitzpatrick 4145bb7148 tailcfg: bump CurrentMapRequestVersion, forgotten earlier 
In f45a9e291b (2021-03-04), I tried to bump CurrentMapRequestVersion

increase it from 11.

Mapver 11 was added in ea49b1e811 (2021-03-03).

Fix this in its own commit so we can cherry-pick it to the 1.6 release
branch.

Brad FitzpatrickandBrad Fitzpatrick d5fd373f09 net/interfaces: skip IPv6 link-local interfaces like we do for IPv4 
We strip them control-side anyway, and we already strip IPv4 link
local, so there's no point uploading them.  And iOS has a ton of them,
which results in somewhat silly amount of traffic in the MapRequest.

We'll be doing same-LAN-inter-tailscaled link-local traffic a
different way, with same-LAN discovery.
