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.

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.

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.

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.

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.
