Now the most part of test cases may be executed in pidns. By default all test cases are executed in current pidns, then they are executed in new pidns again. v2: remove the hard coded path to test_init Signed-off-by:

Create a tmp directory and mount proc from a target pid ns. This proc will show pid-s from the target pid ns. crtools uses map_files for restoring sharing mappings. the tmp directory is removed after restore. Signed-off-by:

Checkpoint and restore do use fdtype_ops and file_desc_ops intensively so reorder pipes functions, this allow us to make them static and drop additional declarations. No func changes. Signed-off-by:
