42d7b014e4
To be able to checkpoint/restart using criu (criu.org) a new CRS component is added which is based on criu. This first commit provides the minimal set of functions and configure script options to enable --with-criu and link against libcriu.so. No actual checkpoint/restart functionality is yet implemented. This is only the framework which needs to be filled with the actual functionality. This commit was SVN r30666.
