David Anderson a447caebf8 version: delete GENERATE.go.
It existed previously to persuade Go that redo-ful directory was
a Go package prior to the first build. But now we have other Go
files in the directory that will fulfil that function.

David Anderson d05b0500ac wgengine: loop back tuntap packets destined for local IPs.
macOS incorrectly sends packets for the local Tailscale IP
into our tunnel interface. We have to turn the packets around
and send them back to the kernel.

Fixes tailscale/corp#189.

Brad Fitzpatrick c3f7733f53 logpolicy: don't check version.CmdName on Windows unnecessarily
... it was crashing for some reason, running out of stack while
loading a DLL in goversion. I don't understand Windows (or the Go
runtime for Windows) enough to know why that'd be problematic in that
context.

In any case, don't call it, as tryFixLogStateLocation does nothing on
Windows anyway.

tryFixLogStateLocation should probably just call version.CmdName
itself if/when it needs to, after the GOOS check.

Avery Pennarun 6f590f5b52 logtail: we missed a case for the backoff timer.
We want to run bo.Backoff() after every upload, regardless. If
upload==true but err!=nil, we weren't backing off, which caused some
very-high-throughput log upload retries in bad network conditions.

Updates #282.

Brad Fitzpatrick 484b7fc9a3 derp, cmd/derper: add frameWatchConns, framePeerPresent for inter-DERP routing
This lets a trusted DERP client that knows a pre-shared key subscribe
to the connection list. Upon subscribing, they get the current set
of connected public keys, and then all changes over time.

This lets a set of DERP server peers within a region all stay connected to
each other and know which clients are connected to which nodes.

David Anderson c62b80e00b cmd/tailscale: fix inverted flag meanings.
The flags were --no-blah for a brief time, then we switched them to
--blah=true/false with a default of true, but didn't fix the boolean
inversions in the code. So up was down, true was false, etc.
