This change is to restore /etc/resolv.conf after tailscale down is called. This is done by setting the dns.Manager before errors occur. Error collection is also added.
Fixes#723
Also remove rebinding logic from the windows router. Magicsock will
instead rebind based on link change signals.

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