Martin Baillie 8ae3ba0cf5 wgengine: define default tunname for each platform
The device name "tailscale0" will be used for all platforms except for
OpenBSD where "tun" is enforced by the kernel. `CreateTUN()` in
`wireguard-go` will select the next available "tunX" device name on the
OpenBSD system.

David Anderson f192c05413 metrics: add a LabelMap type for variables with 1 label dimension.
This lets us publish sets of vars that are breakdowns along one
dimension in a format that Prometheus and Grafana natively know
how to do useful things with.

David Anderson 21fc5ec371 cmd/mkpkg: support specifying that a package replaces another.
Both RPM and Deb require us to specify both Replaces and Conflicts:
Conflicts tells them that the packages cannot coexist on the system,
Replaces tells them which one to keep.

David Anderson 78654ee1bd cmd/tailscale: switch to an ffcli based CLI.
Two commands for now, `up` and `netcheck`. The commands and the flags they take
will change a bunch in the future, but this is good enough to launch on parity
with relaynode.

Brad Fitzpatrick 14559340ee Start of netcheck package & including network state in Hostinfo.
* adds new packet "netcheck" to do the checking of UDP, IPv6, and
  nearest DERP server, and the Report type for all that (and more
  in the future, probably pulling in danderson's natprobe)
* new tailcfg.NetInfo type
* cmd/tailscale netcheck subcommand (tentative name, likely to
  change/move) to print out the netcheck.Report.

Avery Pennarun 57bbafde84 cmd/relaynode: drop local --acl-file in favour of central packet filter.
relaynode itself is not long for this world, deprecated in favour of
tailscale/tailscaled. But now that the control server supports central
distribution of packet filters, let's actually take advantage of it in
a final, backward compatible release of relaynode.

David Anderson 15b4d26d92 logpolicy: automatically figure out paths and filenames.
The autoselection should pick sensible paths for all of:
 - Windows (LocalAppData)
 - Mac (Library/Caches)
 - Unix user (XDG_CACHE_DIR)
 - Linux systemd service (CACHE_DIRECTORY)

As a last resort, if cache dir lookup fails, plops sufficiently
uniquely named files into the current working directory.

David Anderson 4460bd638b safesocket: simplify API.
On unix, we want to provide a full path to the desired unix socket.

On windows, currently we want to provide a TCP port, but someday
we'll also provide a "path-ish" object for a named pipe.

For now, simplify the API down to exactly a path and a TCP port.

David Anderson 21280ca2d1 Make ipn.Options.Prefs a pointer.
This is a prelude to making it truly optional, once state
management has moved into the backend. For now though, it's
still required. This change is just isolating the bubbling-up
of the pointerification into other layers.

David Anderson f6f154193f Remove LoginFlags from Backend options.
- It was only used in one currently-unused client.
- It's an imperative command, not a configuration setting.
- The LoginFlags stuff in controlclient feels like it needs
  a refactor anyway.

I'll put this logic back once ipnd owns its state and Backend
commands reflect that.

David Anderson ea11d58e96 debian: fix changelog generation.
It seems changelog generation got broken by moving the code between
corp and OSS repos, because one of the commit SHAs doesn't have an
associated tag.

In the interest of fixing the build, and because we're not yet trying
to upstream the debian package, I fixed this by allowing hash-based
versions to show up in the changelog. This maybe wrong from a
debian standards perspective, but for our current point in life
it'll work until we learn to do it better.
