Enforcing inclusion of our OSS license at the top of .ts and .tsx
files. Also updates any relevant files in the repo that were
previously missing the license comment. An additional `@license`
comment is added to client/web/src/index.tsx to preserve the
license in generated Javascript.

"Device Authorization" was recently renamed to "Device Approval"
on the control side. This change updates tsconnect to match.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

The window may not end up getting unloaded (if other beforeunload
handlers prevent the event), thus we should only close the SSH session
if it's truly getting unloaded.

We were just logging them to the console, which is useful for debugging,
but we may want to show them in the UI too.

The auto-generated hostname is nice as a default, but there are cases
where the client has a more specific name that it can generate.

The default WebLinksAddon handler uses window.open(), but that gets blocked
by the popup blocker when the event being handled is another window. We
instead need to invoke open() on the window that the event was triggered
in.

More user friendly, and as a side-effect we handle SSH check mode better,
since the URL that's output is now clickable.

Allows other work to be unblocked while xtermjs/xterm.js#4069 is worked
through.
To enable testing the popup window handling, the standalone app allows
opening of SSH sessions in new windows by holding down the alt key
while pressing the SSH button.

We were just outputting them to the terminal, but that's hard to debug
because we immediately tear down the terminal when getting an error.

`src/` is broken up into several subdirectories:
- `lib/` and `types`/ for shared code and type definitions (more code
will be moved here)
- `app/` for the existing Preact-app
- `pkg/` for the new NPM package
A new `build-pkg` esbuild-based command is added to generate the files
for the NPM package. To generate type definitions (something that esbuild
does not do), we set up `dts-bundle-generator`.
Includes additional cleanups to the Wasm type definitions (we switch to
string literals for enums, since exported const enums are hard to use
via packages).
Also allows the control URL to be set a runtime (in addition to the
current build option), so that we don't have to rebuild the package
for dev vs. prod use.

This change allows for an auth key to be specified as a url query param
for use in development mode. If an auth key is specified and valid, it
will authorize the client for use immediately.

Reduces the amount of boilerplate to render the UI and makes it easier to
respond to state changes (e.g. machine getting authorized, netmap changing,
etc.)
Preact adds ~13K to our bundle size (5K after Brotli) thus is a neglibible
size contribution. We mitigate the delay in rendering the UI by having a static
placeholder in the HTML.
Required bumping the esbuild version to pick up evanw/esbuild#2349, which
makes it easier to support Preact's JSX code generation.

JS -> native nodes worked already, tested by exposing a fetch() method
to JS (it's Promise-based to be consistent with the native fetch() API).
Native nodes -> JS almost worked, we just needed to set the LocalBackend
on the userspace netstack.

Makes the terminal container DOM node as large as the window (except for
the header) via flexbox. The xterm.js terminal is then sized to fit via
xterm-addon-fit. Once we have a computed rows/columns size, and we can
tell the SSH session of the computed size.
Required introducing an IPNSSHSession type to allow the JS to control
the SSH session once opened. That alse allows us to programatically
close it, which we do when the user closes the window with the session
still active.
I initially wanted to open the terminal in a new window instead (so that
it could be resizable independently of the main window), but xterm.js
does not appear to work well in that mode (possibly because it adds an
IntersectionObserver to pause rendering when the window is not visible,
and it ends up doing that when the parent window is hidden -- see
xtermjs/xterm.js@87dca56dee8018a17b5cb22ec844b7013629da63)

The go wasm process exiting is a sign of an unhandled panic. Also
add a explicit recover() call in the notify callback, that's where most
logic bugs are likely to happen (and they may not be fatal).
Also fixes the one panic that was encountered (nill pointer dereference
when generating the JS view of the netmap).

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
(which were showing up when invoking any scripts).

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.
