4fea604979 wgengine/router: stop setPrivateNetwork goroutine on configureInterface failure
On Windows, configureInterface starts a goroutine reconfiguring the
Windows firewall.

But if configureInterface fails later, that goroutine kept running and
likely failing forever, spamming logs. Make it stop quietly if its
launching goroutine filed.

fc8bc76e58 wgengine/router: lock goroutine to OS thread before using OLE [windows]
See https://github.com/tailscale/tailscale/issues/921#issuecomment-727526807

Not yet sure whether this is our problem, but it can't hurt at least,
and seems like what we're supposed to do.

3528d28ed1 wgengine/router: move Tailscale's winipcfg additions into wgengine/router
Part of unforking our winipcfg-go and using upstream (#760), move our
additions into our repo. (We might upstream them later if upstream has
interest)

Originally these were:

@apenwarr: "Add ifc.SyncAddresses() and SyncRoutes()."
609dcf2df5

@bradfitz: "winipcfg: make Interface.AddRoutes do as much as possible, return combined error"
e9f93d53f3

@bradfitz: "prevent unnecessary Interface.SyncAddresses work; normalize IPNets in deltaNets"

fd77268770 wgengine/router: enumerate all interfaces when finding Tailscale adapter by GUID
Might fix it. I've spent too much time failing to reproduce the issue. This doesn't
seem to make it worse, though (it still runs for me), so I'll include this and
see if it helps others while I still work on a reliable way to reproduce it.

5bcac4eaac net/tshttpproxy: add GetProxyForURL negative cache
Otherwise when PAC server is down, we log, and each log entry is a new
HTTP request (from logtail) and a new GetProxyForURL call, which again
logs, non-stop. This is also nicer to the WinHTTP service.

Then also hook up link change notifications to the cache to reset it
if there's a chance the network might work sooner.
