Pulled from criu.org/Todo

This is to make --leave-stopped option work -- all tasks are SIGSTOP-ed after restore. And to leave freeze cgroup in frozen state after restore.

log: Add deep lavel and backtrace to log
6d77436 
For the CRIU beginner need additional information about backtrace to fast learn internals.
The message is appended deep level (|...|) at the begin and backtrace at the end {@fn1->fn2...}.
The backtrace appends on change stack and also contains file name and line number.

There are example:
