The main purpose of this patch is to add OverlayFS support to docker_cr.sh
for external checkpoint and restore. It also does a bit of cleaning
and minor enhancements.

This patch adds code to the contrib/docker_cr.sh helper script for trying
to determine the external bind mount file for dockerinit if the user
has not explicitly specified it via the DOCKERINIT_BINARY environment
variable.

Since the command line for checkpointing and restoring Docker containers
is very long and there are some manual steps involved before restoring
a container, it's much easier to use a shell script to automate the work.
One would simply do:
$ sudo docker_cr.sh -c
$ sudo docker_cr.sh -r
