Josh Bleecher Snyder aa9d7f4665 tstime: add Parse3339B, for byte slices 
Use go4.org/mem for memory safety.
A slight performance hit, but a huge performance win
for clients who start with a []byte.
The perf hit is due largely to the MapHash call, which adds ~25ns.
That is necessary to keep the fast path allocation-free.

Maybe because the branch is called main instead of master?

David Anderson 9cd4e65191 smallzstd: new package that constructs zstd small encoders/decoders. 
It's just a config wrapper that passes "use less memory at the
expense of compression" parameters by default, so that we don't
accidentally construct resource-hungry (de)compressors.

Also includes a benchmark that measures the memory cost of the
small variants vs. the stock variants. The savings are significant
on both compressors (~8x less memory) and decompressors (~1.4x less,
not including the savings from the significantly smaller
window on the compression side - with those savings included it's
more like ~140x smaller).

Brad Fitzpatrick e6b84f2159 all: make client use server-provided DERP map, add DERP region support 
Instead of hard-coding the DERP map (except for cmd/tailscale netcheck
for now), get it from the control server at runtime.

And make the DERP map support multiple nodes per region with clients
picking the first one that's available. (The server will balance the
order presented to clients for load balancing)

This deletes the stunner package, merging it into the netcheck package
instead, to minimize all the config hooks that would've been
required.

Also fix some test flakes & races.

Fixes #387 (Don't hard-code the DERP map)
Updates #388 (Add DERP region support)
Fixes #399 (wgengine: flaky tests)

Brad Fitzpatrick 922d9546bf wgengine: don't allocate so much in userspaceEngine.getStatus 
It was one of the top garbage producers on my phone.

It's slated to be deleted and replaced anyway, but this helps in the
meantime.

The go.sum changes look scary, but the new dep only adds 240 bytes to
the binary. The go.sum noise is just cmd/go being aggressive in
including a lot of stuff (which is being fixed in Go 1.15, for what I
understand). And I ran a go mod tidy, which added some too. (I had to
write a custom wrapper around go mod tidy because this mod tidy
normally breaks on tailscale.io/control being missing but referenced
in tests)

David Anderson 78654ee1bd cmd/tailscale: switch to an ffcli based CLI. 
Two commands for now, `up` and `netcheck`. The commands and the flags they take
will change a bunch in the future, but this is good enough to launch on parity
with relaynode.

Brad Fitzpatrick 14559340ee Start of netcheck package & including network state in Hostinfo. 
* adds new packet "netcheck" to do the checking of UDP, IPv6, and
  nearest DERP server, and the Report type for all that (and more
  in the future, probably pulling in danderson's natprobe)
* new tailcfg.NetInfo type
* cmd/tailscale netcheck subcommand (tentative name, likely to
  change/move) to print out the netcheck.Report.

David Crawshaw 7a3be96199 wgengine: add pinger to generate initial spray packets 
For 3 seconds after a successful handshake, wgengine will send a
ping packet every 300ms to its peer. This ensures the spray logic
in magicsock has something to spray.
