Brad Fitzpatrick c1d9e41bef cmd/tailscaled: use "Tailscale" as default TUN device name on Windows
That's what's used in the Windows GUI version and seems special. If we don't use
that, Windows tries to rename it and fails.

Brad Fitzpatrick 6255ce55df Revert "version: don't have a third version number form for xcode"
This reverts commit 5280d039c4.

Turns out to not be possible. The semver form and the human readable
form both must of form x.y.z.

David Anderson 88e8456e9b wgengine/magicsock: add a connectivity test for facing firewalls.
The test demonstrates that magicsock can traverse two stateful
firewalls facing each other, that each require localhost to
initiate connections.

David Anderson b3d65ba943 tstest/natlab: refactor, expose a Packet type.
HandlePacket and Inject now receive/take Packets. This is a handy
container for the packet, and the attached Trace method can be used
to print traces from custom packet handlers that integrate nicely
with natlab's internal traces.

David Anderson 5eedbcedd1 tstest/natlab: add a stateful firewall.
The firewall provides a ProcessPacket handler, and implements an
address-and-port endpoint dependent firewall that allows all
traffic to egress from the trusted interface, and only allows
inbound traffic if corresponding outbound traffic was previously
seen.

David Anderson 0ed9f62ed0 tstest/natlab: provide inbound interface to HandlePacket.
Requires a bunch of refactoring so that Networks only ever
refer to Interfaces that have been attached to them, and
Interfaces know about both their Network and Machine.

Brad Fitzpatrick dba9b96908 version: remove quoting around version name
I added them earlier while fighting our redo+xcode build which wasn't
picking up these files on incremental builds. It still isn't, but now I've
verified with full builds that no quotes is correct.

Brad Fitzpatrick 96d806789f ipn: add Notify.LocalTCPPort field for macOS Network Extension to use
We want the macOS Network Extension to share fate with the UI frontend,
so we need the backend to know when the frontend disappears.

One easy way to do that is to reuse the existing TCP server it's
already running (for tailscale status clietns).

We now tell the frontend our ephemeral TCP port number, and then have
the UI connect to it, so the backend can know when it disappears.

There are likely Swift ways of doing this, but I couldn't find them
quickly enough, so I reached for the hammer I knew.

Brad Fitzpatrick 5280d039c4 version: don't have a third version number form for xcode
Our primary version format is git describe --long --abbrev=9.

Our Apple scheme is:
    (major+100).minor.(patch*10,000+gitDescribeCommits).

This CL gets rid of the third, which was:
    major.minor.(patch*10,000+gitDescribeCommits).

Now the "About" box in the macOS app shows the same version that we
show on pkgs.tailscale.com, userz, changelog, etc.

This will be more important once/if we get standalone DMG downloads
for macOS on pkgs.tailscale.com.

Brad Fitzpatrick 0a5ab533c1 net/netcheck: send dummy packet out to help airport extreme in hairpin check
At least the Apple Airport Extreme doesn't allow hairpin
sends from a private socket until it's seen traffic from
that src IP:port to something else out on the internet.

See https://github.com/tailscale/tailscale/issues/188#issuecomment-600728643

And it seems that even sending to a likely-filtered RFC 5737
documentation-only IPv4 range is enough to set up the mapping.
So do that for now. In the future we might want to classify networks
that do and don't require this separately. But for now help it.

I've confirmed that this is enough to fix the hairpin check on Avery's
home network, even using the RFC 5737 IP.

Brad Fitzpatrick 630379a1d0 cmd/tailscale: add tailscale status region name, last write, consistently star
There's a lot of confusion around what tailscale status shows, so make it better:
show region names, last write time, and put stars around DERP too if active.

Now stars are always present if activity, and always somewhere.
