[CRIU] [PATCH 0/6] Sanitize collect phase

[Pavel Emelyanov]

When reading in images we call several routines manually that
makes the code look not perfect.

At the same time there's already some machinery that allows
just to declare what to collect and then run the collecting
code(s) in a loop.

This set tunes most of the collections made from root task
work automatically and reduces the number of code lines.
