Also remove rebinding logic from the windows router. Magicsock will
instead rebind based on link change signals.

Josh Bleecher Snyder 3f4d93feb2 go.mod: bump depaware to get diffs out of -check, again
I had to use

go get -u github.com/tailscale/depaware@e09ee10c18249e4bf198e66bbd47babcd502637a

to force it to the correct version; it kept selecting head~1.

Maybe because the branch is called main instead of master?
Maybe because of some delay?

Brad Fitzpatrick f65eb4e5c1 net/netstat: start of new netstat package, with Windows for now
This will be used in a future change to do localhost connection
authentication. This lets us quickly map a localhost TCP connection to
a PID. (A future change will then map a pid to a user)

TODO: pull portlist's netstat code into this package. Then portlist
will be fast on Windows without requiring shelling out to netstat.exe.

log/logheap: properly document LogHeap as performing HTTP upload (#741)
LogHeap no longer logs to os.Stderr and instead uploads
the heap profile by means of an HTTP POST request to the
target URL endpoint.

While here, also ensured that an error from pprof.WriteHeapProfile
isn't ignored and will prevent the HTTP request from being made
if non-nil.

Josh Bleecher Snyder 7bd89359c9 cmd/cloner: generate a package-level Clone function
This Clone function knows how to clone any types
for which it has generated Clone methods.
This allows callers to efficiently clone
an inbound interface{} that might contain one of these types.

Josh Bleecher Snyder 2352690bde cmd/cloner: ensure cloner gets re-run when structs change
If you change a struct and don't re-run cloner,
your Cloner method might be inaccurate, leading to bad things.

To prevent this, write out the struct as it is at the moment that
cloner is caller, and attempt a conversion from that type.
If the struct gets changed in any way, this conversion will fail.

This will yield false positives: If you change a non-pointer field,
you will be forced to re-run cloner, even though the actual generated
code won't change. I think this is an acceptable cost: It is a minor
annoyance, which will prevent real bugs.

Brad Fitzpatrick 8ecee476f6 ipn: simplify TestLocalLogLines, defer a Shutdown of its LocalBackend
The test's LocalBackend was not shut down (Shutdown both releases
resources and waits for its various goroutines to end). This should
fix the test race we were seeing. It definitely fixes the file
descriptor leak that preventing -race -count=500 from passing before.

Brad Fitzpatrick b026a638c7 net/tshttpproxy: if winhttp.GetProxyForURL blocks too long, use previous value
We currently have a chickend-and-egg situation in some environments
where we can set up routes that WinHTTP's WPAD/PAC resolution service
needs to download the PAC file to evaluate GetProxyForURL, but the PAC
file is behind a route for which we need to call GetProxyForURL to
e.g. dial a DERP server.

As a short-term fix, just assume that the most recently returned proxy
is good enough for such situations.

Josh Bleecher Snyder a570c27577 portlist: reduce log spam on macOS
Running tailscaled on my machine yields lots of entries like:

weird: missing {tcp 6060}

parsePortsNetstat is filtering out loopback addresses as uninteresting.
Then addProcesses is surprised to discover these listening ports,
which results in spurious logging.
Teach addProcesses to also ignore loopback addresses.
