Brad Fitzpatrick 666d404066 ipn: put discovery key generation behind an environment flag for now
Later we'll want to use the presence of a discovery key as a signal
that the node knows how to participate in discovery. Currently the
code generates keys and sends them to the control server but doesn't
do anything with them, which is a bad state to stay in lest we release
this code and end up with nodes in the future that look like they're
functional with the new discovery protocol but aren't.

So for now, make this opt-in as a debug option for now, until the rest
of it is in.

Brad Fitzpatrick abd79ea368 derp: reduce DERP memory use; don't require callers to pass in memory to use
The magicsock derpReader was holding onto 65KB for each DERP
connection forever, just in case.

Make the derp{,http}.Client be in charge of memory instead. It can
reuse its bufio.Reader buffer space.

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.
