all: make client use server-provided DERP map, add DERP region support
...
Instead of hard-coding the DERP map (except for cmd/tailscale netcheck
for now), get it from the control server at runtime.
And make the DERP map support multiple nodes per region with clients
picking the first one that's available. (The server will balance the
order presented to clients for load balancing)
This deletes the stunner package, merging it into the netcheck package
instead, to minimize all the config hooks that would've been
required.
Also fix some test flakes & races.
Fixes #387 (Don't hard-code the DERP map)
Updates #388 (Add DERP region support)
Fixes #399 (wgengine: flaky tests)

wgengine: generate and plumb router.Settings in from ipn.
...
This saves a layer of translation, and saves us having to
pass in extra bits and pieces of the netmap and prefs to
wgengine. Now it gets one Wireguard config, and one OS
network stack config.

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.
