Cubic performs better than Reno in higher BDP scenarios, and enables the
use of the hystart++ implementation contributed by Coder. This improves
throughput on higher BDP links with a much faster ramp.
gVisor is bumped as well for some fixes related to send queue processing
and RTT tracking.

The upstream crypto package now supports sending banners at any time during
authentication, so the Tailscale fork of crypto/ssh is no longer necessary.
github.com/tailscale/golang-x-crypto is still needed for some custom ACME
autocert functionality.
tempfork/gliderlabs is still necessary because of a few other customizations,
mostly related to TTY handling.
Originally implemented in 46fd4e58a27495263336b86ee961ee28d8c332b7,
which was reverted in b60f6b849af1fae1cf343be98f7fb1714c9ea165 to
keep the change out of v1.80.

For 9dd6af1f6d
Update client/web and safeweb to correctly signal to the csrf middleware
whether the request is being served over TLS. This determines whether
Origin and Referer header checks are strictly enforced. The gorilla
library previously did not enforce these checks due to a logic bug based
on erroneous use of the net/http.Request API. The patch to fix this also
inverts the library behavior to presume that every request is being
served over TLS, necessitating these changes.

Most of these are effectively no-ops, but appease security scanners.

Adds a new reconciler that reconciles ExternalName Services that define a
tailnet target that should be exposed to cluster workloads on a ProxyGroup's
proxies.
The reconciler ensures that for each such service, the config mounted to
the proxies is updated with the tailnet target definition and that
and EndpointSlice and ClusterIP Service are created for the service.
Adds a new reconciler that ensures that as proxy Pods become ready to route
traffic to a tailnet target, the EndpointSlice for the target is updated
with the Pods' endpoints.

This adds a systray app for linux, similar to the apps for macOS and
windows. There are already a number of community-developed systray apps,
but most of them are either long abandoned, are built for a specific
desktop environment, or simply wrap the tailscale CLI.
This uses fyne.io/systray (a fork of github.com/getlantern/systray)
which uses newer D-Bus specifications to render the tray icon and menu.
This results in a pretty broad support for modern desktop environments.
This initial commit lacks a number of features like profile switching,
device listing, and exit node selection. This is really focused on the
application structure, the interaction with LocalAPI, and some system
integration pieces like the app icon, notifications, and the clipboard.

This commit implements TCP GRO for packets being written to gVisor on
Linux. Windows support will follow later. The wireguard-go dependency is
updated in order to make use of newly exported IP checksum functions.
gVisor is updated in order to make use of newly exported
stack.PacketBuffer GRO logic.
TCP throughput towards gVisor, i.e. TUN write direction, is dramatically
improved as a result of this commit. Benchmarks show substantial
improvement, sometimes as high as 2x. High bandwidth-delay product
paths remain receive window limited, bottlenecked by gVisor's default
TCP receive socket buffer size. This will be addressed in a follow-on
commit.
The iperf3 results below demonstrate the effect of this commit between
two Linux computers with i5-12400 CPUs. There is roughly ~13us of round
trip latency between them.
The first result is from commit 57856fc without TCP GRO.

This commit implements TCP GSO for packets being read from gVisor on
Linux. Windows support will follow later. The wireguard-go dependency is
updated in order to make use of newly exported GSO logic from its tun
package.
A new gVisor stack.LinkEndpoint implementation has been established
(linkEndpoint) that is loosely modeled after its predecessor
(channel.Endpoint). This new implementation supports GSO of monster TCP
segments up to 64K in size, whereas channel.Endpoint only supports up to
32K. linkEndpoint will also be required for GRO, which will be
implemented in a follow-on commit.
TCP throughput from gVisor, i.e. TUN read direction, is dramatically
improved as a result of this commit. Benchmarks show substantial
improvement through a wide range of RTT and loss conditions, sometimes
as high as 5x.
The iperf3 results below demonstrate the effect of this commit between
two Linux computers with i5-12400 CPUs. There is roughly ~13us of round
trip latency between them.
