[CRIU] [PATCH v4 5/8] p.haul: add necessary operations on shared ploops

[Alexander Burluka]

That commit introduces methods that are used in migration
scenario with shared ploops. These operations are simply
consistent calling of appropriate ploop method.
Initialization, restoring, cleanup and gathering info
are implemented that way.
