[CRIU] [PATCH 0/6] Restore tree into --unshare context

[Pavel Emelyanov]

Hi,

This is a resurrected and just minimally tested set that introduces
the --unshare option that forces the restored tree into a fresh new
set of namespaces.

This is not for inclusion into tree, but rather for comments and for
additional help, as I'm not sure whether I will be able to play with
this set a significant amount of time :(

First two patches are just cleanups, find more details in the patches
3 through 6.
