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.

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 1d7f9d5b4a59b3e, the revert of 4224b3f73110f6f.
At least it's fast again, even if it's shelling out to cmd.exe (once now).

gVisor fixed their google/gvisor#1446 so we can include gVisor mode
on 32-bit machines.
A few minor upstream API changes, as normal.

We basically already had the RIB-parsing Go code for this in both
net/interfaces and wgengine/monitor, for other reasons.

This change makes it impossible to set your own IP address as the exit node for this system.

So a region can be used if needed, but won't be STUN-probed or used as
its home.
This gives us another possible debugging mechanism for #1310, or can
be used as a short-term measure against DERP flip-flops for people
equidistant between regions if our hysteresis still isn't good enough.

This reverts commit 08949d4ef1082a4373b552d3901351e7a297c62d.
I think this code was aspirational. There's no code that sets up the
appropriate NAT code using pfctl/etc. See #911 and #1475.

No server support yet, but we want Tailscale 1.6 clients to be able to respond
