Brad Fitzpatrick 8049053f86 ipn/*: make new WindowsUserID type to consolidate docs
The "userID is empty everywhere but Windows" docs on lots of places
but not everywhere while using just a string type was getting
confusing. This makes a new type to wrap up those rules, however
weird/historical they might be.

Brad Fitzpatrick 3b73727e39 cmd/tailscale: de-punycode hostnames in status display
Still show original, but show de-punycode version in parens,
similar to how we show DNS-less hostnames.

Brad Fitzpatrick 5676d201d6 ipn: add a WatchIPNBus option bit to subscribe to EngineStatus changes
So GUI clients don't need to poll for it.

We still poll internally (for now!) but that's still cheaper. And will
get much cheaper later, without having to modify clients once they
start sending this bit.

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 b0545873e5 ipn/ipnserver: remove protoSwitchConn shenanigans; just use http.Server early
Now that everything's just HTTP, there's no longer a need to have a
header-sniffing net.Conn wraper that dispatches which route to
take. Refactor to just use an http.Server earlier instead.

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.

Brad Fitzpatrick 1fdfb0dd08 ipn/localapi: add "enginestatus" debug command to LocalAPI
To force an EngineStatus update to the IPN bus.

This is a temporary measure while migrating the Windows GUI entirely
to the LocalAPI and off the old IPN protocol. The old IPN protocol
had RequestEngineStatus and LocalAPI didn't.

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.

Fixes https://github.com/tailscale/tailscale/issues/3137

This matches CanSSHD (TS_DISABLE_SSH_SERVER) for administratively

This can be configured in /etc/default/tailscaled on Linux,
%ProgramData%\Tailscale\tailscaled-env.txt on Windows,
or /etc/tailscale/tailscaled-env.txt on Synology. (see getPlatformEnvFile)

Also delete some dead code and tidy up some docs.

We're trying to gut 90% of the ipnserver package. A lot will get
