fe7c3e9c17 all: move wgcfg from wireguard-go 
This is mostly code movement from the wireguard-go repo.

Most of the new wgcfg package corresponds to the wireguard-go wgcfg package.

wgengine/wgcfg/device{_test}.go was device/config{_test}.go.
There were substantive but simple changes to device_test.go to remove
internal package device references.

The API of device.Config (now wgcfg.DeviceConfig) grew an error return;
we previously logged the error and threw it away.

1e28207a15 types/logger: fix rateFree interaction with verbosity prefixes 
We log lines like this:

c.logf("[v1] magicsock: disco: %v->%v (%v, %v) sent %v", c.discoShort, dstDisco.ShortString(), dstKey.ShortString(), derpStr(dst.String()), disco.MessageSummary(m))

The leading [v1] causes it to get unintentionally rate limited.
Until we have a proper fix, work around it.

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.

4fea604979 wgengine/router: stop setPrivateNetwork goroutine on configureInterface failure 
On Windows, configureInterface starts a goroutine reconfiguring the
Windows firewall.

But if configureInterface fails later, that goroutine kept running and
likely failing forever, spamming logs. Make it stop quietly if its
launching goroutine filed.

This enables us to use upstream wireguard-go logging,
but maintain the Tailscale-style peer public key identifiers
that the rest of our systems (and people) expect.

This change mostly affects us, running tailscaled as root by hand (wit
a umask of 0077), not under systemd. End users running tailscaled
under systemd won't have a umask.
