[CRIU] [PATCH v2 0/3] vzct: c/r kernel.core_pattern sysctl

[Pavel Tikhomirov]

Make our virtualized kernel.core_pattern properly c/r, thus
creating universal post-c/r plugin to c/r any custom props
for example Virtuozzo specitic staff with criu.

We can reuse open_image_at, pb_read_one and pb_write_one in criu
plugin and save all custom props to vzct.img in protobuf format.

One can reuse POST_DUMP, POST_RESTORE plugin hooks for own plugin, it
is not for VZCT plugin only, use it as alternative to action-scripts.
