This sets a default packet filter that blocks all incoming requests,
giving end users more control over who can get into their machine, even
if the admin hasn't set any central ACLs.

Prefs has become a heavy object with non-memcpy copy
semantics. We should not pass such a thing by value.

We can't rely on a frontend to provide a control
server URL, so this naturally belongs in server-persisted
state.

This is a prelude to supporting relaynode's --routes in
tailscaled. The daemon needs to remembers routes to
advertise, and the CLI needs to be able to change the
set of advertised routes. Prefs is the thing used for
both of these.

The store is passed-in by callers of NewLocalBackend and
ipnserver.Run, but currently all callers are hardcoded to
an in-memory store. The store is unused.

This is a prelude to making it truly optional, once state
management has moved into the backend. For now though, it's
still required. This change is just isolating the bubbling-up
of the pointerification into other layers.
