Brad Fitzpatrick f45106d47c ipn/ipnserver: move Windows-specific code to tailscaled_windows.go
We'll eventually remove it entirely, but for now move get it out of ipnserver
where it's distracting and move it to its sole caller.

Brad Fitzpatrick f3ba268a96 ipn/ipnserver: move BabysitProc to tailscaled_windows.go
It's only used by Windows. No need for it to be in ipn/ipnserver,
which we're trying to trim down.

Brad Fitzpatrick 7e016c1d90 ipn/ipnserver: remove IPN protocol server
Unused in this repo as of the earlier #6450 (300aba61a6)
and unused in the Windows GUI as of tailscale/corp#8065.

With this ipn.BackendServer is no longer used and could also be
removed from this repo. The macOS and iOS clients still temporarily
depend on it, but I can move it to that repo instead while and let its
migration proceed on its own schedule while we clean this repo up.

Aaron Klotz 033bd94d4c cmd/tailscaled, wgengine/router: use wingoes/com for COM initialization instead of go-ole
This patch removes the crappy, half-backed COM initialization used by `go-ole`
and replaces that with the `StartRuntime` function from `wingoes`, a library I
have started which, among other things, initializes COM properly.

In particular, we should always be initializing COM to use the multithreaded
apartment. Every single OS thread in the process becomes implicitly initialized
as part of the MTA, so we do not need to concern ourselves as to whether or not
any particular OS thread has initialized COM. Furthermore, we no longer need to
lock the OS thread when calling methods on COM interfaces.

Single-threaded apartments are designed solely for working with Win32 threads
that have a message pump; any other use of the STA is invalid.

Maisem Ali 235309adc4 all: store NL keys per profile
This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct.
This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey.

It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional
to be able to delete the "/tka" dir if it exists.

This means that we will have a unique key per profile, and a unique directory per profile.

Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not
delete the ChonkDir.

David Anderson 76904b82e7 cmd/containerboot: PID1 for running tailscaled in a container.
This implements the same functionality as the former run.sh, but in Go
and with a little better awareness of tailscaled's lifecycle.

Also adds TS_AUTH_ONCE, which fixes the unfortunate behavior run.sh had
where it would unconditionally try to reauth every time if you gave it
an authkey, rather than try to use it only if auth is actually needed.
This makes it a bit nicer to deploy these containers in automation, since
you don't have to run the container once, then go and edit its definition
to remove authkeys.

If a JSON object looks like a network log message,
then unmarshal it as one and then print it.
This allows netlogfmt to support both a stream of JSON objects
directly serialized from netlogtype.Message, or the schema
returned by the /api/v2/tailnet/{{tailnet}}/network-logs API endpoint.

types/netlogtype: new package for network logging types (#6092)
The netlog.Message type is useful to depend on from other packages,
but doing so would transitively cause gvisor and other large packages
to be linked in.

Avoid this problem by moving all network logging types to a single package.

We also update staticcheck to take in:

Mihai Parparita d60f7fe33f cmd/tsconnect: run wasm-opt on the generated wasm file
Saves about 1.4MB from the generated wasm file. The Brotli size is
basically unchanged (it's actually slightly larger, by 40K), suggesting
that most of the size delta is due to not inlining and other changes
that were easily compressible.

However, it still seems worthwhile to have a smaller final binary, to
reduce parse time and increase likelihood that we fit in the browser's
disk cache. Actual performance appears to be unchanged.

The Lufthansa in-flight wifi generates a synthetic 204 response to the

challenge/response to the endpoint; something sufficiently complicated
that it's unlikely to be implemented by a captive portal. We can then
check for the expected response to verify whether we're being MITM'd.

Anton Tolchanov c070d39287 cmd/tailscaled: handle tailscaled symlink on macOS
When Tailscale is installed via Homebrew, `/usr/local/bin/tailscaled`
is a symlink to the actual binary.

Now when `tailscaled install-system-daemon` runs, it will not attempt
to overwrite that symlink if it already points to the tailscaled binary.
However, if executed binary and the link target differ, the path will
he overwritten - this can happen when a user decides to replace
Homebrew-installed tailscaled with a one compiled from source code.

David Anderson bdf3d2a63f cmd/pgproxy: open-source our postgres TLS-enforcing proxy.
From the original commit that implemented it:

  It accepts Postgres connections over Tailscale only, dials
  out to the configured upstream database with TLS (using
  strong settings, not the swiss cheese that postgres defaults to),
  and proxies the client through.

  It also keeps an audit log of the sessions it passed through,
  along with the Tailscale-provided machine and user identity
  of the connecting client.

In our other repo, this was:
commit 92e5edf98e8c2be362f564a408939a5fc3f8c539,
