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.

Signed-off-by: David Anderson <danderson@tailscale.com>

* 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.

David Crawshaw f53792026e tstest/integration/vms: move build tags from linux to !windows
The tests build fine on other Unix's, they just can't run there.
But there is already a t.Skip by default, so `go test` ends up
working fine elsewhere and checks the code compiles.

Christine Dodrill 0b9e938152 tstest/integration/vms: test DNS configuration
This uses a neat little tool to dump the output of DNS queries to
standard out. This is the first end-to-end test of DNS that runs against
actual linux systems. The /etc/resolv.conf test may look superflous,
however this will help for correlating system state if one of the DNS
tests fails.

David Crawshaw 8668103f06 tstest/integration/vms: print qemu console output, fix printing issues
Fix a few test printing issues when tests fail.

Qemu console output is super useful when something is wrong in the
harness and we cannot even bring up the tests.
Also useful for figuring out where all the time goes in tests.

A little noisy, but not too noisy as long as you're only running one VM
as part of the tests, which is my plan.

David Crawshaw bb47feca44 tstest/integration: prefix logs with logid
The VM test has two tailscaled instances running and interleaves the
logs. Without a prefix it is impossible to figure out what is going on.

It might be even better to include the [ABCD] node prefix here as well.
Unfortunately lots of interesting logs happen before tailscaled has a
node key, so it wouldn't be a replacement for a short ID.

tstest/integration/vms: disable rDNS for sshd on centos (#2492)
This prevents centos tests from timing out because sshd does reverse dns
lookups on every session being established instead of doing it once on
the acutal ssh connection being established. This is odd. Appending this
to the sshd config and restarting it seems to fix it though.

Josh Bleecher Snyder 4b1f2ae382 tstest/integration: generate deps for all platforms in deps generator
We have different deps depending on the platform.
If we pick a privileged platform, we'll miss some deps.
If we use the union of all platforms, the integration test
won't compile on some platforms, because it'll import
packages that don't compile on that platform.

Give in to the madness and give each platform its own deps file.

tstest/integration/vms: codegen for top level tests (#2441)
This moves the distribution definitions into a maintainable hujson file
instead of just existing as constants in `distros.go`. Comments are
maintained from the inline definitions.

This uses jennifer[1] for hygenic source tree creation. This allows us
to generate a unique top-level test for each VM run. This should
hopefully help make the output of `go test` easier to read.

This also separates each test out into its own top-level test so that we
can better track the time that each distro takes. I really wish there
was a way to have the `test_codegen.go` file _always_ run as a part of
the compile process instead of having to rely on people remembering to
run `go generate`, but I am limited by my tools.

This will let us remove the `-distro-regex` flag and use `go test -run`
to pick which distros are run.

Regression from 6d10655dc3, which added
UpdatePrefs but didn't write it out to disk.

I'd planned on adding tests to state_test.go which is why I'd earlier

such persistence tests easier to write, but turns out state_test.go
didn't even test UpdatePrefs, so I'm staying out of there.

tstest/integration/vms: unbreak nixos builds (#2372)
To avoid the generated nixos disk images from becoming immune from the
GC, I delete the symlink to the nix store at the end of tests.
`t.Cleanup` runs at the end of a test. I changed this part of the code
to have a separate timer for how long it takes to run NixOS builds, but
I did that by using a subtest. This means that it was creating the NixOS
image, deleting its symlink and then trying to use that symlink to find
the resulting disk image, making the whole thing ineffectual.

This was a mistake. I am reverting this change made in
https://github.com/tailscale/tailscale/pull/2360 to remove this layer of
subtesting.
