[CRIU] [PATCH 0/6] Introduce orderliness in pstree_item::ids on restore

[Kirill Tkhai]

We have many checks for pstree_item::ids over the restore code,
and all of them are excess, because a task always has ids
after the commit 848578a7be98 "pstree: Assign ids for dead tasks
in read_pstree_image()".

Also, we have many checks for pstree_item::ids::has_xxx_ns_id,
which are excess for the most of them (pid, net, ipc, uts, mnt),
because they exist before the criu stabilized its images format
(commit 2105e18eee70).

This patchset continues to introduce orderliness in pstee_item::ids,
and it makes sanity checks of task's ids and the above has_xxx_ns_id
in the only place. That allows to remove them from the rest of code
and make it simplier.
