Josh Bleecher Snyder 8c2cb4b431 go.mod: update to latest certstore
It includes a fix to allow us to use Go 1.18.
We can now remove our Tailscale-only build tags.

Josh Bleecher Snyder 26021b07ec control/controlclient: only build certstore-related code with the Tailscale Go toolchain
The certstore code is impacted by golang/go#51726.
The Tailscale Go toolchain fork contains a temporary workaround,
so it can compile it. Once the upstream toolchain can compile certstore,
presumably in Go 1.18.1, we can revert this change.

Note that depaware runs with the upstream toolchain.

Adrian Dewhurst adda2d2a51 control/controlclient: select newer certificate
If multiple certificates match when selecting a certificate, use the one
issued the most recently (as determined by the NotBefore timestamp).
This also adds some tests for the function that performs that
comparison.

types/key: add a special key with custom serialization for control private keys (#2792)
* Revert "Revert "types/key: add MachinePrivate and MachinePublic.""

This reverts commit 61c3b98a24.

* types/key: add ControlPrivate, with custom serialization.

ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.

Adrian Dewhurst 6d6cf88d82 control/controlclient: use our fork of certstore
The cyolosecurity fork of certstore did not update its module name and
thus can only be used with a replace directive. This interferes with
installing using `go install` so I created a tailscale fork with an
updated module name.

Adrian Dewhurst 3f456ba2e7 control/controlclient: return correct certificate
When searching for the matching client identity, the returned
certificate chain was accidentally set to that of the last identity
returned by the certificate store instead of the one corresponding to
the selected identity.

Also, add some extra error checking for invalid certificate chains, just
in case.

control/controlclient: sign RegisterRequest (#1549)
control/controlclient: sign RegisterRequest

Some customers wish to verify eligibility for devices to join their
tailnets using machine identity certificates. TLS client certs could
potentially fulfill this role but the initial customer for this feature
has technical requirements that prevent their use. Instead, the
certificate is loaded from the Windows local machine certificate store
and uses its RSA public key to sign the RegisterRequest message.

There is room to improve the flexibility of this feature in future and
it is currently only tested on Windows (although Darwin theoretically
works too), but this offers a reasonable starting place for now.
