This has the benefit of propagating SIGINT to tailscaled, which in turn
can react to the event and logout in case of an ephemeral node.
Also fix missing run.sh in Dockerfile.

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.

We now have the actual module that we need to build, so switch to
building it directly instead of its (expected) dependencies.
Also fix a copy/paste error in a jsdeps comment.

The control plane server doesn't send these to modern clients so we
don't need them in the tree. The server has its own serialization code
to generate legacy MapResponses when needed.

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 PR implements the synchronization mechanics for TKA: generating a SyncOffer, processing a SyncOffer to find an intersection,
and computing the set of AUMs that should be transmitted to effect convergence.
This is the final PR implementing core mechanics for TKA.

This lets us distinguish "no IPv6 because the device's ISP doesn't
offer IPv6" from "IPv6 is unavailable/disabled in the OS".

QTS 5.0 doesn't always pass a qtoken, in some circumstances
it sends a NAS_SID cookie for us to verify instead.

We were not handling errors occurred while copying data between the subprocess and the connection.
This makes it so that we pass the appropriate signals when to the process and the connection.
This also fixes mosh.

FS implements Chonk, and given the expected load characteristics (frequent use
of AUM() + ChildAUMs(), and infrequent use of Heads() + CommitVerifiedAUMs()), the
implementation avoids scanning the filesystem to service AUM() and ChildAUMs().

We make assertions about stringification of 0.5. IEEE floating point and
all reasonable proprietary floating point can exactly represent 0.5.
We don't make assertions about other floating point values, too brittle
in tests.

Chonks are responsible for efficient storage of AUMs and other TKA state.
For testing/prototyping I've implemented an in-memory version, but once we
start to use this from tailscaled we'll need a file-based version.

This is the first in a series of PRs implementing the internals for the
Tailnet Key Authority. This PR implements the AUM and Key types, which
are used by pretty much everything else. Future PRs:
- The State type & related machinery
- The Tailchonk (storage) type & implementation
- The Authority type and sync implementation

If ConfigFromFile cannot find the configuration file,
we must not initialize it with NewConfig.
Instead, we need it to fail validation so that it eventually writes
a newly constructed configuration file.
Otherwise, new tailscale instances will never be able store a persistent
log config and start with a new config file upon every bootup.
