[CRIU] [PATCH cr 0/8] Restore SID

[Andrey Vagin]

We need to reconstruct a processes tree, because a sid can't be set,
it may be only inherit.

Thre fundamental cases exist:
* A session leader is dead
  - add a fake task
* A task is detached to init
  - add a fake task and connect it to the session leader
* A parent forked a child, then changed own sid
  - determining a sid with which the parent was born.

Andrey Vagin (8):
  zdtm: add new test case for checking that SID is restored
  pstree: simplify access to pid, real_pid, born_sid
  restore: calculate a maximum value of PID-s
  restore: add interface for creating helper tasks
  restore: restore sids of tasks, which have been reparented to init
  restore: restore sid of task which isn't leaders and isn't a child of
    init
  restore: print message about sid only if it's restored
  restorer: exit all threads in case of error
