David Crawshaw 7a3be96199 wgengine: add pinger to generate initial spray packets
For 3 seconds after a successful handshake, wgengine will send a
ping packet every 300ms to its peer. This ensures the spray logic
in magicsock has something to spray.

David Crawshaw 4ebc0fa70f wgengine: incremental update of peers on network map change
This is the first, and easier, part of incremental wireguard-go
reconfiguration. It means that a new node appearing on the
network does not cause all existing nodes to re-handshake with
the other nodes they are talking to.

(This code has been running on hello.ipn.dev for a few weeks and
peers have successfully reconnected to it through many network
map updates.)

* make RouterGen return an error, not take both tunname and tundev
* also remove RouteGen taking a wireguard/device.Device; currently unused
