Brad Fitzpatrick e98cdbb8b6 util/winutil: add little Windows utility package
Code from Alex Brainman, split out of another change. I changed it to
a comma-ok return and tweaked the docs a bit.

Josh Bleecher Snyder 635e4c7435 wgengine/magicsock: increase legacy ping timeout again
I based my estimation of the required timeout based on locally
observed behavior. But CI machines are worse than my local machine.
16s was enough to reduce flakiness but not eliminate it. Bump it up again.

tailcfg: update node display name fields and methods (#1207)
Signed-off-by: Sonia Appasamy <sonia@tailscale.com>

Consolidates the node display name logic from each of the clients into
tailcfg.Node. UI clients can use these names directly, rather than computing
them independently.

Brad Fitzpatrick 5efb0a8bca cmd/tailscale: change formatting of "tailscale status"
* show DNS name over hostname, removing domain's common MagicDNS suffix.
  only show hostname if there's no DNS name.
  but still show shared devices' MagicDNS FQDN.

* remove nerdy low-level details by default: endpoints, DERP relay,
  public key.  They're available in JSON mode still for those who need
  them.

* only show endpoint or DERP relay when it's active with the goal of
  making debugging easier. (so it's easier for users to understand
  what's happening) The asterisks are gone.

* remove Tx/Rx numbers by default for idle peers; only show them when
  there's traffic.

* include peers' owner login names

* add CLI option to not show peers (matching --self=true, --peers= also
  defaults to true)

* sort by DNS/host name, not public key

* reorder columns

Brad Fitzpatrick 5f07da4854 util/systemd: don't log warnings when not running under systemd
It caused our integration tests to fail, which prohibit logging to
os.Stderr for test cleanliness reasons.

Christine Dodrill 7ea809897d ipn/ipnserver: enable systemd-notify support
Addresses #964

Still to be done:
- Figure out the correct logging lines in util/systemd
- Figure out if we need to slip the systemd.Status function anywhere
  else
- Log util/systemd errors? (most of the errors are of the "you cannot do
  anything about this, but it might be a bad idea to crash the program if
  it errors" kind)

Assistance in getting this over the finish line would help a lot.

Josh Bleecher Snyder a5dd0bcb09 util/jsonutil: new package
The cornerstone API is a more memory-efficient Unmarshal.
The savings come from re-using a json.Decoder.

BenchmarkUnmarshal-8      	 4016418	       288 ns/op	       8 B/op	       1 allocs/op
BenchmarkStdUnmarshal-8   	 4189261	       283 ns/op	     184 B/op	       2 allocs/op

It also includes a Bytes type to reduce allocations
when unmarshalling a non-hex-encoded JSON string into a []byte.

Josh Bleecher Snyder 9784cae23b util/uniq: add new package
This makes it easy to compact slices that contain duplicate elements
by sorting and then uniqing.

This is an alternative to constructing an intermediate map
and then extracting elements from it. It also provides
more control over equality than using a map key does.
