Brad Fitzpatrick 322cb58b14 derp: deflake test I flaked up in earlier change
I broke an invariant in 11048b8932 (it was even nicely
documented then).

Also clean up the test a bit from while I was debugging it.

Fixes #84

David Anderson c47f907a27 ipn: use *Prefs rather than Prefs throughout.
Prefs has become a heavy object with non-memcpy copy
semantics. We should not pass such a thing by value.

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.)

Avery Pennarun 57bbafde84 cmd/relaynode: drop local --acl-file in favour of central packet filter.
relaynode itself is not long for this world, deprecated in favour of
tailscale/tailscaled. But now that the control server supports central
distribution of packet filters, let's actually take advantage of it in
a final, backward compatible release of relaynode.

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. If it has,
we end up with a redeclaration conflict.

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.

David Anderson cf1e386cbd ipn: move Options.ServerURL into Prefs.
We can't rely on a frontend to provide a control

David Anderson 4460bd638b safesocket: simplify API.
On unix, we want to provide a full path to the desired unix socket.

On windows, currently we want to provide a TCP port, but someday
we'll also provide a "path-ish" object for a named pipe.

For now, simplify the API down to exactly a path and a TCP port.

David Anderson a5b84fa921 ipn: add AdvertiseRoutes to Prefs.
This is a prelude to supporting relaynode's --routes in
tailscaled. The daemon needs to remembers routes to
advertise, and the CLI needs to be able to change the
set of advertised routes. Prefs is the thing used for
both of these.
