The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

Allows imports of the NPM package added by 1a093ef482
to be replaced with import("http://localhost:9090/pkg/pkg.js"), so that
changes can be made in parallel to both the module and code that uses
it (without any need for NPM publishing or even building of the package).

`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.

We can't write to src/ when tsconnect is used a dependency in another
repo (see also b763a12331). We therefore
need to switch from writing to src/ to using esbuild plugins to handle
the requests for wasm_exec.js (the Go JS runtime for Wasm) and the
Wasm build of the Go module.
This has the benefit of allowing Go/Wasm changes to be picked up without
restarting the server when in dev mode (Go compilation is fast enough
that we can do this on every request, CSS compilation continues to be
the long pole).

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.

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`.

Avoids waterfalling of requests from the file (its load is triggered
from JavaScript).
Also has other cleanups to index.html, adding a <title> and moving the
<script> to being loaded sooner (but still not delaying page rendering
by using the defer attribute).

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).

Continues to use esbuild for development mode and building. Also
includes a `yarn lint` script that uses tsc to do full type checking.

Adds a tool/yarn helper script that uses specific versions of yarn and
node, downloading them if necessary.
Modeled after tool/go (and the yarn and node Redo scripts from the
corp repo).
Also allows the path to yarn to be overidden (in case the user does not
want to use this script) and always pipes yarn output (to make debugging
and viewing of process easier).

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.
