Brad Fitzpatrick deac82231c wgengine/magicsock: add start of alternate send path ... During development of silent disco (#540), an alternate send policy for magicsock that doesn't wake up the radio frequently with heartbeats, we want the old & new policies to coexist, like we did previously pre- and post-disco. We started to do that earlier in 5c42990c2f but only set up the env+control knob plumbing to set a bool about which path should be used. This starts to add a way for the silent disco code to update the send path from a separate goroutine. (Part of the effort is going to de-state-machinify the event based soup that is the current disco code and make it more Go synchronous style.) So far this does nothing. (It does add an atomic load on each send but that should be noise in the grand scheme of things, and a even more rare atomic store of nil on node config changes.) Baby steps.
