We want to allow docker to mount tmpfs directories over existing directories
in the image. We will use this patch to pass commands from docker to
libcontainer. The first command we will use is the tar command to gather
all of the contents of the destination directory before mounting, then after
we mount the post mount command will untar the content.

Change the various config structs into one package and have a flatter
structure for easier use.
