[CRIU] [PATCH 0/9] creds: Implement support of per-threds credentials

[Cyrill Gorcunov]

Currently we can dump tasks which have same credentials over
the all process tree. This makes us unable to dump for example
Openswan. Lets make creds being per-thread as they should be
from the very beginning but wasn't in sake of simplicily.

Guys, give it a look please, once time permit. I tested the
series over real container with openswan running inside but
not that intensively.

Comments are highly appreciated.
