And move a couple other types down into leafier packages.
Now cmd/tailscale doesn't bring in netlink, magicsock, wgengine, etc.

These accidentally make the tag syntax more flexible than was intended,
which will create forward compatibility problems later. Let's go back
to the old stricter parser.
Revert "cmd/tailscale/cli: fix double tag: prefix in tailscale up"
Revert "cmd/tailscale/cli, tailcfg: allow tag without "tag:" prefix in 'tailscale up'"
This reverts commit a702921620f7b6e386f393a9a1340d4218597469.

This partially (but not yet fully) migrates Windows to tailscaled's
StateStore storage system.
This adds a new bool Pref, ForceDaemon, defined as:
// ForceDaemon specifies whether a platform that normally
// operates in "client mode" (that is, requires an active user
// logged in with the GUI app running) should keep running after the
// GUI ends and/or the user logs out.
//
// The only current applicable platform is Windows. This
// forced Windows to go into "server mode" where Tailscale is
// running even with no users logged in. This might also be
// used for macOS in the future. This setting has no effect
// for Linux/etc, which always operate in daemon mode.
Then, when ForceDaemon becomes true, we now write use the StateStore
to track which user started it in server mode, and store their prefs
under that key.
The ipnserver validates the connections/identities and informs that
LocalBackend which userid is currently in charge.
The GUI can then enable/disable server mode at runtime, without using
the CLI.
But the "tailscale up" CLI was also fixed, so Windows users can use
authkeys or ACL tags, etc.
Updates #275
We depend on DERP for NAT traversal now[0] so disabling it entirely can't
work.
What we'll do instead in the future is let people specify
alternate/additional DERP servers. And perhaps in the future we could
also add a pref for nodes to say when they expect to never need/want
to use DERP for data (but allow it for NAT traversal communication).
But this isn't the right pref and it doesn't work, so delete it.

For now. Get it working again so it's not stuck on 0.98.
Subnet relay can come later.
