949ec78653 don't set ConnectionState to nil (#590)
* don't set ConnectionState to nil

We might have packets processing in another thread, so we can't safely
just set this to nil. Since we removed it from the hostmaps, the next
packets to process should start the handshake over again.

I believe this comment is outdated or incorrect, since the next
handshake will start over with a new HostInfo, I don't think there is
any way a counter reuse could happen:

> We must null the connectionstate or a counter reuse may happen

Here is a panic we saw that I think is related:

    panic: runtime error: invalid memory address or nil pointer dereference

When running in `-test` mode, `tun` is set to nil. So we should move the
defer into the `!configTest` if block.

75306487c5 fix wintun package to have // +build comments (#598)
Without these comments, gofmt 1.16.9 will complain. Since we otherwise
still support building with go1.16, lets add the comments to make it
easier to compile and gofmt.

304b12f63f create ConnectionState before adding to HostMap (#535)
We have a few small race conditions with creating the HostInfo.ConnectionState
since we add the host info to the pendingHostMap before we set this
field. We can make everything a lot easier if we just add an "init"
function so that we can set this field in the hostinfo before we add it
to the hostmap.

ea2c186a77 remote_allow_ranges: allow inside CIDR specific remote_allow_lists (#540)
This allows you to configure remote allow lists specific to different
subnets of the inside CIDR. Example:

    remote_allow_ranges:
      10.42.42.0/24:
        192.168.0.0/16: true

This would only allow hosts with a VPN IP in the 10.42.42.0/24 range to
have private IPs (and thus don't connect over public IPs).

The PR also refactors AllowList into RemoteAllowList and LocalAllowList to make it clearer which methods are allowed on which allow list.

ae5505bc74 handshake: update to preferred remote (#532)
If we receive a handshake packet for a tunnel that has already been
completed, check to see if the new remote is preferred. If so, update to
the preferred remote and send a test packet to influence the other side
to do the same.

3a8f533b24 refactor: use X25519 instead of ScalarBaseMult (#533)
As suggested in https://pkg.go.dev/golang.org/x/crypto/curve25519#ScalarBaseMult,
use X25519 instead of ScalarBaseMult. When using Basepoint, it may employ
some precomputed values, enhancing performance.

34d002d695 Check CA cert and key match in nebula-cert sign (#503)
`func (nc *NebulaCertificate) VerifyPrivateKey(key []byte) error` would
previously return an error even if passed the correct private key for a
CA certificate `nc`.

That function has been updated to support CA certificates, and
nebula-cert now calls it before signing a new certificate. Previously,
it would perform all constraint checks against the CA certificate
provided, take a SHA256 fingerprint of the provided certificate, insert
it into the new node certificate, and then finally sign it with the
mismatching private key provided.
