2c2dff9559 tsweb: don't panic if we get a tsweb.Error with no embedded error. 
It's technically weird to return a tsweb.Error with no child err,
but it's a sensible thing to want to do, and we shouldn't panic
if it happens.

48d7ee1c6a cmd/microproxy: adjust to export node stats and a Go expvar server's stats. 
This is a temporary specialization to what tailscale prod needs right now,
it'll go back to something more generic later.

0590ad68be controlclient, ipn: adjust tests for authURL semantic changes 
The tests cheat at filling out web forms by directly POSTing to
the target. The target for authURLs has changed slightly, the base
authURL now redirects the user to the login page.

Additionally, the authURL cycle now checks the cookie is set
correctly, so we add cookie jars where necessary to pass the
cookie through.

dbca186a64 stunner: fix data race. 
In very low-latency conditions, a STUN request can complete before
the startup loop has finished firing off goroutines, leading to

f53e78e0d5 wgengine: don't lose filter state on filter reconfig. 
We were abandoning the UDP port LRU every time we got a new packet
filter from tailcontrol, which caused return packets to suddenly stop
arriving.

8454bbbda5 wgengine/magicsock: more logging improvements 
* remove endpoint discovery noise when results unchanged
* consistently spell derp nodes as "derp-N"
* replace "127.3.3.40:" with "derp-" in CreateEndpoint log output
* stop early DERP setup before SetPrivateKey is called;
  it just generates log nosie
* fix stringification of peer ShortStrings (it had an old %x on it,
  rendering it garbage)
* describe why derp routes are changing, with one of:
  shared home, their home, our home, alt

8c4cef60f8 derp: wait for send goroutine to finish before returning from run 
I saw a test flake due to the sender goroutine logging (ultimately to
t.Logf) after the server was closed.

This makes sure the all goroutines are cleaned up before Server.Close
returns.
