7d8feb2784 hostinfo: change Windows implementation to directly query version information using API and registry
We replace the cmd.exe invocation with RtlGetNtVersionNumbers for the first
three fields. On Windows 10+, we query for the fourth field which is available
via the registry.

The fourth field is not really documented anywhere; Firefox has been querying
it successfully since Windows 10 was released, so we can be pretty confident in
its longevity at this point.

Fixes https://github.com/tailscale/tailscale/issues/1478

e6fbc0cd54 cmd/tailscaled, ipn/ipnserver: refactor ipnserver
More work towards removing the massive ipnserver.Run and ipnserver.Options
and making composable pieces.

Work remains. (The getEngine retry loop on Windows complicates things.)
For now some duplicate code exists. Once the Windows side is fixed
to either not need the retry loop or to move the retry loop into a
custom wgengine.Engine wrapper, then we can unify tailscaled_windows.go
too.

4528f448d6 ipn/store/aws, cmd/tailscaled: add AWS SSM ipn.StateStore implementation
From https://github.com/tailscale/tailscale/pull/1919 with
edits by bradfitz@.

This change introduces a new storage provider for the state file. It
allows users to leverage AWS SSM parameter store natively within
tailscaled, like:

    $ tailscaled --state=arn:aws:ssm:eu-west-1:123456789:parameter/foo

Known limitations:
- it is not currently possible to specific a custom KMS key ID

RELNOTE=tailscaled on Linux supports using AWS SSM for state
