Checkpoint-restore tool v1.5

Hello, everyone!

The 1.5 is out. With it we have the image manipulation tool called CRIT, AIO rings support, additional stuff for Docker (fd inheritance and automatic veth-to-bridge assignment) and more objects to C/R inside user-namespaces.

Plus bug fixes, of course.

Thanks,
