This adds the first code to checkpoint a container. The checkpoint command is name 'checkpointt' (with two 't's at the end) so that container engines like Podman do not think to use this not yet finished checkpoint restore implementation. For Podman it is still necessary to tell CRIU that the network namespace is external at least and restoring needs special handling to support '--console-socket'.

Also connect stdin to /dev/null for test containers
If stdin is not pointing to /dev/null checkpointing fails for now. Just point it to /dev/null. Signed-off-by: Adrian Reber <areber@redhat.com>

This still uses the subcommand 'checkpointt' until it works in combination with Podman. Signed-off-by: Adrian Reber <areber@redhat.com>
