So we can empty import the guts of cmd/tailscaled from another
module for go mod tidy reasons.

This adds an easy and portable way for us to document how to get
your Tailscale IP address.
$ tailscale ip
100.74.70.3
fd7a:115c:a1e0:ab12:4843:cd96:624a:4603
$ tailscale ip -4
100.74.70.3
$ tailscale ip -6

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.

Mash up some code from ffcli and std's flag package to make a default
usage func that's super explicit for those not familiar with the Go
style flags. Only show double hyphens in usage text (but still accept both),
and show default values, and only show the proper usage of boolean flags.

"public IP" is defined as an IP address configured on the exit node
itself that isn't in the list of forbidden ranges (RFC1918, CGNAT,
Tailscale).
Fixes#1522.

The direct client already logs it in JSON form. Then it's immediately
logged again in an unformatted dump, so this removes that unformatted
one.

This reverts the revert commit 84aba349d9.

In f45a9e291b (2021-03-04), I tried to bump CurrentMapRequestVersion
to 12 but only documented the meaning of 12 but forgot to actually
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.
Should help iOS battery life on NEProvider.wake/skip events
with useless route updates that shouldn't cause re-STUNs.

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.

To atone for 1d7f9d5b4a, the revert of 4224b3f731.
At least it's fast again, even if it's shelling out to cmd.exe (once now).
