David Anderson 22507adf54 wgengine/magicsock: stop depending on UpdateDst in legacy codepaths.
This makes connectivity between ancient and new tailscale nodes slightly
worse in some cases, but only in cases where the ancient version would
likely have failed to get connectivity anyway.

Josh Bleecher Snyder 56a7652dc9 wgkey: new package
This is a replacement for the key-related parts
of the wireguard-go wgcfg package.

This is almost a straight copy/paste from the wgcfg package.
I have slightly changed some of the exported functions and types
to avoid stutter, added and tweaked some comments,
and removed some now-unused code.

To avoid having wireguard-go depend on this new package,
wgcfg will keep its key types.

We translate into and out of those types at the last minute.
These few remaining uses will be eliminated alongside
the rest of the wgcfg package.

Brad Fitzpatrick 309c15dfdd types/key: restore Curve25519 clamping in NewPrivate
It was lost during a copy from wgcfg.NewPresharedKey (which doesn't
clamp) instead of wgcfg.NewPrivateKey (which does).

Fortunately this was only use for discovery messages (not WireGuard)
and only for ephemeral process-lifetime keys.

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)
