Marwan Sulaiman f232d4554a cmd/tailscale: translate old serve commands to new ones
This PR fixes the isLegacyInvocation to better catch serve and
funnel legacy commands. In addition, it now also returns a string
that translates the old command into the new one so that users
can have an easier transition story.

clientupdate: change Mac App Store support (#9891)
In the sandboxed app from the app store, we cannot check
`/Library/Preferences/com.apple.commerce.plist` or run `softwareupdate`.
We can at most print a helpful message and open the app store page.

Also, reenable macsys update function to mark it as supporting c2n
updates. macsys support in `tailscale update` was fixed.

cmd/tailscale: improve taildrop progress printer on Linux (#9878)
The progress printer was buggy where it would not print correctly
and some of the truncation logic was faulty.

The progress printer now prints something like:

	go1.21.3.linux-amd64.tar.gz               21.53MiB      13.83MiB/s     33.88%    ETA 00:00:03

where it shows
* the number of bytes transferred so far
* the rate of bytes transferred
  (using a 1-second half-life for an exponentially weighted average)
* the progress made as a percentage
* the estimated time
  (as calculated from the rate of bytes transferred)

Other changes:
* It now correctly prints the progress for very small files
* It prints at a faster rate (4Hz instead of 1Hz)
* It uses IEC units for byte quantities
  (to avoid ambiguities of "kb" being kilobits or kilobytes)

cmd/tailscale/cli: [serve/funnel] support omitting scheme for TCP (#9856)
The `serve` command for TCP  has always required the scheme of the target to be specified. However, when it's omitted the error message reported is misleading

```
error: failed to apply TCP serve: invalid TCP target "localhost:5900": missing port in address
```

Since we know the target is TCP, we shouldn't require it to be specified. This aligns with the changes for HTTP proxies in https://github.com/tailscale/tailscale/issues/8489

the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

Will Norris d74c771fda client/web: always use new web client; remove old client
This uses the new react-based web client for all builds, not just with
the --dev flag.

If the web client assets have not been built, the client will serve a
message that Tailscale was built without the web client, and link to
build instructions. Because we will include the web client in all of our
builds, this should only be seen by developers or users building from
source. (And eventually this will be replaced by attempting to download
needed assets as runtime.)

We do now checkin the build/index.html file, which serves the error
message when assets are unavailable.  This will also eventually be used
to trigger in CI when new assets should be built and uploaded to a
well-known location.

Brad Fitzpatrick 4511e7d64e ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User
In b987b2ab18 (2021-01-12) when we introduced sharing we mapped
the sharer to the userid at a low layer, mostly to fix the display of
"tailscale status" and the client UIs, but also some tests.

The commit earlier today, 7dec09d169, removed the 2.5yo option
to let clients disable that automatic mapping, as clearly we were never
getting around to it.

This plumbs the Sharer UserID all the way to ipnstatus so the CLI
itself can choose to print out the Sharer's identity over the node's
original owner.

Then we stop mangling Node.User and let clients decide how they want
to render things.

To ease the migration for the Windows GUI (which currently operates on
tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus),
a new method Node.SharerOrUser is added to do the mapping of
Sharer-else-User.

Netcheck no longer performs I/O itself, instead it makes requests via
SendPacket and expects users to route reply traffic to
ReceiveSTUNPacket.

Netcheck gains a Standalone function that stands up sockets and
goroutines to implement I/O when used in a standalone fashion.

Magicsock now unconditionally routes STUN traffic to the netcheck.Client
that it hosts, and plumbs the send packet sink.

The CLI is updated to make use of the Standalone mode.

Aaron Klotz 7adf15f90e cmd/tailscale/cli, util/winutil/authenticode: flesh out authenticode support
Previously, tailscale upgrade was doing the bare minimum for checking
authenticode signatures via `WinVerifyTrustEx`. This is fine, but we can do
better:

* WinVerifyTrustEx verifies that the binary's signature is valid, but it doesn't
  determine *whose* signature is valid; tailscale upgrade should also ensure that
  the binary is actually signed *by us*.
* I added the ability to check the signatures of MSI files.
* In future PRs I will be adding diagnostic logging that lists details about
  every module (ie, DLL) loaded into our process. As part of that metadata, I
  want to be able to extract information about who signed the binaries.

This code is modelled on some C++ I wrote for Firefox back in the day. See
https://searchfox.org/mozilla-central/rev/27e4816536c891d85d63695025f2549fd7976392/toolkit/xre/dllservices/mozglue/Authenticode.cpp

This change introduces a new subcommand, `exit-node`, along with a

Exit nodes without location data will continue to be displayed when
`status` is used. Exit nodes with location data will only be displayed
behind `exit-node list`, and in status if they are the active exit node.

The `filter` flag can be used to filter exit nodes with location data by
country.

Exit nodes with Location.Priority data will have only the highest
priority option for each country and city listed. For countries with
multiple cities, a <Country> <Any> option will be displayed, indicating
the highest priority node within that country.

initializing code deep within gvisor that panicked on init on arm64

This deletes the unused code to delete the imports and remove the
panic. We can then cherry-pick this back to the branch and restore it
later in a different way.

A new test makes sure we don't regress in the future by depending on
the panicking package in question.

Additionally, this adds a LocalAPI endpoint and associated

We can remove the arm32 one though, since we don't support 32-bit ARM on Windows.

Mihai Parparita 9cb332f0e2 sockstats: instrument networking code paths
Uses the hooks added by tailscale/go#45 to instrument the reads and
writes on the major code paths that do network I/O in the client. The
convention is to use "<package>.<type>:<label>" as the annotation for
the responsible code path.

Enabled on iOS, macOS and Android only, since mobile platforms are the
ones we're most interested in, and we are less sensitive to any
throughput degradation due to the per-I/O callback overhead (macOS is
also enabled for ease of testing during development).

For now just exposed as counters on a /v0/sockstats PeerAPI endpoint.

We also keep track of the current interface so that we can break out
the stats by interface.

Andrew Dunham 2755f3843c health, net/tlsdial: add healthcheck for self-signed cert
When we make a connection to a server, we previously would verify with
the system roots, and then fall back to verifying with our baked-in
Let's Encrypt root if the system root cert verification failed.

We now explicitly check for, and log a health error on, self-signed
certificates. Additionally, we now always verify against our baked-in
Let's Encrypt root certificate and log an error if that isn't
successful. We don't consider this a health failure, since if we ever
change our server certificate issuer in the future older non-updated
versions of Tailscale will no longer be healthy despite being able to
connect.

Add `tailscale version --json` JSON output mode. This will be used
later for a double-opt-in (per node consent like Tailscale SSH +
control config) to let admins do remote upgrades via `tailscale
update` via a c2n call, which would then need to verify the
cmd/tailscale found on disk for running tailscale update corresponds
to the running tailscaled, refusing if anything looks amiss.

Plus JSON output modes are just nice to have, rather than parsing
unstable/fragile/obscure text formats.
