David Crawshaw	a6ad3c46e2	magicsock: spray some normal packets after a handshake ... In particular, this is designed to catch the case where a HandshakeInitiation packet is sent out but the intermediate NATs have not been primed, so the packet passes over DERP. In that case, the HandshakeResponse also comes back over DERP, and the connection proceeds via DERP without ever trying to punch through the NAT. With this change, the HandshakeResponse (which was sprayed out and so primed one NAT) triggers an UpdateDst, which triggers the extra spray logic. (For this to work, there has to be an initial supply of packets to send on to a peer for the three seconds following a handshake. The source of these packets is left as a future exercise.)

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.)

David Anderson	77907a76a3	version: tag redo-generated version as +build redo. ... staticcheck defaults to running with no tags set, which only works if redo hasn't run and generated ver.go.

David Anderson	15b4d26d92	logpolicy: automatically figure out paths and filenames. ... The autoselection should pick sensible paths for all of: - Windows (LocalAppData) - Mac (Library/Caches) - Unix user (XDG_CACHE_DIR) - Linux systemd service (CACHE_DIRECTORY) As a last resort, if cache dir lookup fails, plops sufficiently uniquely named files into the current working directory.
