The create/start split left checkpoint/restore broken in that the create
side was calling runc restore, which fully restores the process to
operation, leaving a call to `runc start` as an error (process already
started). This patch skips process.Start as it is an unnecessary (and
wrong) step for a restored checkpoint.

This fixes a sync issue when the containerd api returns after a
container has started. It fixes it by calling the runtime start inside
containerd after the oom handler has been setup.

Because we are launching alot of different runc commands to do
operations there is a race between doing a `cmd.Wait()` and getting the
sigchld and reaping it. We can remove the sigchild reaper from
containerd as long as we make sure we reap the shim process if we are
the parent, i.e. not restored.

Windows will not use containerd and its just unused code and unneed
complexity to keep it all around.
Signed-off-by: Michael Crosby <crosbymichael@gmail.com>
Windows is not going to use containerd because there is already a
similar implementation on windows. This removes all the windows files
because there is no reason to keep this overhead when its not going to
be used.

Truncate the event log on disk and in memory so that it does not
grow forever. This is mainly used for higher levels to receive past
events if they miss any.

The oom control file may not exist if the container is short lived and
exits before we can open it.

This currently depends on a runc PR:
https://github.com/opencontainers/runc/pull/703
We need this pr because we have to SIGKILL runc and the container root
dir will still be left around.
As for the containerd changes this adds a flag to containerd so that you
can configure the timeout without any more code changes. It also adds
better handling in the error cases and will kill the containerd-shim and
runc ( as well as the user process if it exists ) if the timeout is hit.

This allows you to pass options like:
```bash

```

If the shim gets sigkilled while containerd is down we need to be able
to remove the container correctly so that it does not stay in a stopped
state forever.
