Pavel Emelyanov c9c41ddfa9 img: Remove empty lazy images after dump
If dump doesn't generate data into some image file the respective file
is not created at all as it used to be in 1.5. This brings potential
problem -- if the file with the image name exists during dump (e.g. a
dump file left from previous, maybe unsuccessful, dump) then restore
would pick this file and read bad/wrong/fake data from it.

To return the proper behavior back the file with the name of empty image
should be removed.

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
