Mihai Parparita 8158dd2edc cmd/tsconnect: allow SSH connection timeout to be overridden
5 seconds may not be enough if we're still loading the derp map and
connecting to a slow machine.

Mihai Parparita c312e0d264 cmd/tsconnect: allow hostname to be specified
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.

Mihai Parparita 2400ba28b1 cmd/tsconnect: handle terminal resizes before the SSH session is created
Store the requested size is a struct field, and use that when actually
creating the SSH session.

Mihai Parparita 27f36f77c3 cmd/tsconnect: output errors to the JS console too
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.

Mihai Parparita 1a093ef482 cmd/tsconnect: extract NPM package for reusing in other projects
`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.

tsconnect: pass in authkey in dev mode (#5320)
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.

Mihai Parparita ab159f748b cmd/tsconnect: switch UI to Preact
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.

tsconnect: add flag to specify control server (#5294)
To improve the local development experience, this change allows a
control url to be passed in with the `--dev-control=` flag.

If the flag is passed in when not specifying dev, an error is returned.

If no flag is passed, the default remains the Tailscale controlled
control server set by `ipn.DefaultControlURL`.

Mihai Parparita f371a1afd9 cmd/tsconnect: make logtail uploading work
Initialize logtail and provide an uploader that works in the
browser (we make a no-cors cross-origin request to avoid having to
open up the logcatcher servers to CORS).

Mihai Parparita adc5ffea99 cmd/tsconnect: make PeerAPI work
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.

Mihai Parparita 9a2171e4ea cmd/tsconnect: make terminal resizable
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@87dca56dee)

Mihai Parparita a3d74c4548 cmd/tsconnect: add basic panic handling
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).

Then delete some stuff from the net/netaddr shim package which is no
longer neeed.

Mihai Parparita 6f5096fa61 cmd/tsconnect: initial scaffolding for Tailscale Connect browser client
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.
