also send it via control for finding peers by a list.

This makes setup more explicit in prod codepaths, without
requiring a bunch of arguments or helpers for tests and
userspace mode.

control/controlclient: sign RegisterRequest
Some customers wish to verify eligibility for devices to join their
tailnets using machine identity certificates. TLS client certs could
potentially fulfill this role but the initial customer for this feature
has technical requirements that prevent their use. Instead, the
certificate is loaded from the Windows local machine certificate store
and uses its RSA public key to sign the RegisterRequest message.
There is room to improve the flexibility of this feature in future and
it is currently only tested on Windows (although Darwin theoretically
works too), but this offers a reasonable starting place for now.

So we can empty import the guts of cmd/tailscaled from another
module for go mod tidy reasons.

This adds an easy and portable way for us to document how to get
your Tailscale IP address.

Mash up some code from ffcli and std's flag package to make a default
usage func that's super explicit for those not familiar with the Go
style flags. Only show double hyphens in usage text (but still accept both),
and show default values, and only show the proper usage of boolean flags.

I think this code was aspirational. There's no code that sets up the
appropriate NAT code using pfctl/etc. See #911 and #1475.

The debub subcommand was moved in
6254efb9ef because the monitor brought
in tons of dependencies to the cmd/tailscale binary, but there wasn't
any need to remove the whole subcommand itself.
Add it back, with a tool to dump the local daemon's goroutines.

Part of overall effort to clean up, unify, use link monitoring more,
and make Tailscale quieter when all networks are down. This is especially
bad on macOS where we can get killed for not being polite it seems.
(But we should be polite in any case)
