Brad Fitzpatrick 4145bb7148 tailcfg: bump CurrentMapRequestVersion, forgotten earlier
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.

Brad 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.

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.

Brad Fitzpatrick 387e83c8fe wgengine/magicsock: fix Conn.Rebind race that let ErrClosed errors be read
There was a logical race where Conn.Rebind could acquire the
RebindingUDPConn mutex, close the connection, fail to rebind, release
the mutex, and then because the mutex was no longer held, ReceiveIPv4
wouldn't retry reads that failed with net.ErrClosed, letting that
error back to wireguard-go, which would then stop running that receive
IP goroutine.

Instead, keep the RebindingUDPConn mutex held for the entirety of the
replacement in all cases.

Brad Fitzpatrick fee74e7ea7 net/interfaces, wgengine/monitor: fix false positives link changes
interfaces.State.String tries to print a concise summary of the
network state, removing any interfaces that don't have any or any
interesting IP addresses. On macOS and iOS, for instance, there are a
ton of misc things.

But the link monitor based its are-there-changes decision on
interfaces.State.Equal, which just used reflect.DeepEqual, including
comparing all the boring interfaces. On macOS, when turning wifi on or off, there
are a ton of misc boring interface changes, resulting in hitting an earlier
check I'd added on suspicion this was happening:

    [unexpected] network state changed, but stringification didn't

This fixes that by instead adding a new
interfaces.State.RemoveUninterestingInterfacesAndAddresses method that
does, uh, that. Then use that in the monitor. So then when Equal is
used later, it's DeepEqualing the already-cleaned version with only
interesting interfaces.

This makes cmd/tailscaled debug --monitor much less noisy.
