This is v2 of the 'Introduce CAP_CHECKPOINT_RESTORE' patchset. The
difference from v1 are:

 * Renamed CAP_RESTORE to CAP_CHECKPOINT_RESTORE
 * Added a test
 * Added details about CRIU's use of map_files
 * Allow changing /proc/self/exe link with CAP_CHECKPOINT_RESTORE

The biggest difference is that the patchset now provides all the
changes, which are necessary to use CRIU to checkpoint and restore a
process as non-root if CAP_CHECKPOINT_RESTORE is set.
