Adrian Reber bc169fefb1 RPC: add script to test the new RPC version interface 
This script connects to 'criu swrk' and asks for the version. If running
from a git checkout the output would look like this:

 $ ./version.py
 Connecting to CRIU in swrk mode to check the version:
 RPC: Success
 CRIU major 2
 CRIU minor 12
 CRIU gitid v2.12-635-g6d3ae4d

If not running from git checkout it looks like this:

 $ ./version.py
 Connecting to CRIU in swrk mode to check the version:
 RPC: Success
 CRIU major 2
 CRIU minor 12

If running with a CRIU binary which does not support the VERSION
command:

 $ ./version.py
 Connecting to CRIU in swrk mode to check the version:
 Error (cr-service.c:116): RPC error: Invalid req: Success
 RPC: Unexpected msg type

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.
