The poller is slow by default, but speeds up for a bit after a network
change, in case WPAD/PAC files are still loading.

Brad Fitzpatrick ce1b52bb71 wgengine/monitor: fix other potential crashes on Linux
Never return "nil, nil" anymore. The caller expected a usable
interface now. I missed some of these earlier.

Also, handle address deletion now.

Brad Fitzpatrick 5c1e443d34 wgengine/monitor: don't call LinkChange when interfaces look unchanged
Basically, don't trust the OS-level link monitor to only tell you
interesting things. Sanity check it.

Also, move the interfaces package into the net directory now that we
have it.

* remove derp parameter (it'll work differently)
* unexport NewUserspaceRouter in per-OS impls, add documented wrapper
