Integrates Tailwind CSS as an esbuild plugin that invokes the CLI
to process the input. It takes ~400ms, so it seems like the easiest
option (vs running a separate process for dev mode).
Existing minimal look and feel is replicated with Tailwind classes,
mostly to prove that the entire system works, including unused
class removal.
Also fixes yarn warnings about package.json not having a license

This allows gitops-pusher to detect external ACL changes. I'm not
sure what to call this problem, so I've been calling it the "three
version problem" in my notes. The basic problem is that at any given
time we only have two versions of the ACL file at any given point:
the version in CONTROL and the one in the git repo. In order to
check if there has been tampering of the ACL files in the admin
panel, we need to have a _third_ version to compare against.
In this case I am not storing the old ACL entirely (though that could
be a reasonable thing to add in the future), but only its sha256sum.
This allows us to detect if the shasum in control matches the shasum
we expect, and if that expectation fails, then we can react
accordingly.
This will require additional configuration in CI, but I'm sure that
can be done.

When using tsconnect as a module in another repo, we cannot write to
the ./dist directory (modules directories are read-only by default -
there is a -modcacherw flag for `go get` but we can't count on it).
We add a -distdir flag that is honored by both the build and serve
commands for where to place output in.
Somewhat tedious because esbuild outputs paths relative to the working
directory, so we need to do some extra munging to make them relative
to the output directory.

Runs a Tailscale client in the browser (via a WebAssembly build of the
wasm package) and allows SSH access to machines. The wasm package exports
a newIPN function, which returns a simple JS object with methods like
start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh
package is used for the SSH client.
Terminal emulation and QR code renedring is done via NPM packages (xterm
and qrcode respectively), thus we also need a JS toolchain that can
install and bundle them. Yarn is used for installation, and esbuild
handles loading them and bundling for production serving.

This does three things:
* If you're on GCP, it adds a *.internal DNS split route to the
metadata server, so we never break GCP DNS names. This lets people
have some Tailscale nodes on GCP and some not (e.g. laptops at home)
without having to add a Tailnet-wide *.internal DNS route.
If you already have such a route, though, it won't overwrite it.
* If the 100.100.100.100 DNS forwarder has nowhere to forward to,
it forwards it to the GCP metadata IP, which forwards to 8.8.8.8.
This means there are never errNoUpstreams ("upstream nameservers not set")
errors on GCP due to e.g. mangled /etc/resolv.conf (GCP default VMs
don't have systemd-resolved, so it's likely a DNS supremacy fight)
* makes the DNS fallback mechanism use the GCP metadata IP as a
fallback before our hosted HTTP-based fallbacks
I created a default GCP VM from their web wizard. It has no
systemd-resolved.
I then made its /etc/resolv.conf be empty and deleted its GCP
hostnames in /etc/hosts.
I then logged in to a tailnet with no global DNS settings.
With this, tailscaled writes /etc/resolv.conf (direct mode, as no
systemd-resolved) and sets it to 100.100.100.100, which then has
regular DNS via the metadata IP and *.internal DNS via the metadata IP
as well. If the tailnet configures explicit DNS servers, those are used
instead, except for *.internal.
This also adds a new util/cloudenv package based on version/distro
where the cloud type is only detected once. We'll likely expand it in
the future for other clouds, doing variants of this change for other
popular cloud environments.

AFAICT this isn't documented on MSDN, but based on the issue referenced below,
NRPT rules are not working when a rule specifies > 50 domains.
This patch modifies our NRPT rule generator to split the list of domains
into chunks as necessary, and write a separate rule for each chunk.
For compatibility reasons, we continue to use the hard-coded rule ID, but
as additional rules are required, we generate new GUIDs. Those GUIDs are
stored under the Tailscale registry path so that we know which rules are ours.
I made some changes to winutils to add additional helper functions in support
of both the code and its test: I added additional registry accessors, and also
moved some token accessors from paths to util/winutil.

Once a stop request is received and the service updates its status to `svc.StopPending`,
it should continue running *until the shutdown sequence is complete*, and then
return out of `(*ipnService).Execute`, which automatically sends a `svc.Stopped`
notification to Windows.
To make this happen, I changed the loop so that it runs until `doneCh` is
closed, and then returns. I also removed a spurious `svc.StopPending` notification
that the Windows Service Control Manager might be interpreting as a request for
more time to shut down.
Finally, I added some optional logging that sends a record of service notifications
to the Windows event log, allowing us to more easily correlate with any Service
Control Manager errors that are sent to the same log.

Attempt to load the xt_mark kernel module when it is not present. If the
load fails, log error information.
It may be tempting to promote this failure to an error once it has been
in use for some time, so as to avoid reaching an error with the iptables
invocation, however, there are conditions under which the two stages may
disagree - this change adds more useful breadcrumbs.
Example new output from tailscaled running under my WSL2:
```
router: ensure module xt_mark: "/usr/sbin/modprobe xt_mark" failed: exit status 1; modprobe: FATAL: Module xt_mark not found in directory /lib/modules/5.10.43.3-microsoft-standard-WSL2
```
Background:
There are two places to lookup modules, one is `/proc/modules` "old",
the other is `/sys/module/` "new".
There was query_modules(2) in linux <2.6, alas, it is gone.
In a docker container in the default configuration, you would get
/proc/modules and /sys/module/ both populated. lsmod may work file,
modprobe will fail with EPERM at `finit_module()` for an unpriviliged
container.
In a priviliged container the load may *succeed*, if some conditions are
met. This condition should be avoided, but the code landing in this
change does not attempt to avoid this scenario as it is both difficult
to detect, and has a very uncertain impact.
In an nspawn container `/proc/modules` is populated, but `/sys/module`
does not exist. Modern `lsmod` versions will fail to gather most module
information, without sysfs being populated with module information.
In WSL2 modules are likely missing, as the in-use kernel typically is
not provided by the distribution filesystem, and WSL does not mount in a
module filesystem of its own. Notably the WSL2 kernel supports iptables
marks without listing the xt_mark module in /sys/module, and
/proc/modules is empty.
On a recent kernel, we can ask the capabilities system about SYS_MODULE,
that will help to disambiguate between the non-privileged container case
and just being root. On older kernels these calls may fail.

* This listens over a UNIX socket instead of a TCP socket to prevent

* This uses systemd socket activation so that systemd owns the socket
and can then lock down the service to the bare minimum required to do
its job without having to worry about dropping permissions
* This provides additional information in HTTP response headers that can
be useful for integrating with various services
* This has a script to automagically create debian and redhat packages

In the future we'll probably want to run the "tailscale web"
server instead, but for now stop the infinite restart loop.
See https://gokrazy.org/userguide/process-interface/ for details.

One of the current few steps to run Tailscale on gokrazy is to
specify the --tun=userspace-networking flag:
https://gokrazy.org/userguide/install/tailscale/
Instead, make it the default for now. Later we can change the
default to kernel mode if available and fall back to userspace
mode like Synology, once #391 is done.
Likewise, set default paths for Gokrazy, as its filesystem hierarchy
is not the Linux standard one. Instead, use the conventional paths as
documented at https://gokrazy.org/userguide/install/tailscale/.

If it's in a non-standard table, as it is on Unifi UDM Pro, apparently.

Turns out we're pretty good already at init-time work in tailscaled.
The regexp/syntax shows up but it's hard to get rid of that; zstd even
uses regexp. *shrug*

For local dev testing initially. Product-wise, it'll probably only be
workable on the two unsandboxed builds.

The MSI installer sets a special sentinel value that we can use to detect it.
I also removed the code that bails out when the installation path is not
`Program Files`, as both the NSIS and MSI installers permit the user to install
to a different path.
