[CRIU] [RESEND PATCH v2 0/3] Process Migration using Sockets

[Katerina Koukiou]

Resend patch series because I forgot to add to commit image.h resulting in
build error.

Changes v1 -> v2:
 -rearranged the patches so that the one that adds the implementation required
 to enable the remote option comes first.
 -rebased patches to criu-dev and not master branch as the previous time
 -fixed the changes suggested by Mike Rapoport.

Note: In criu/mem.c I needed to skip the following check when --remote
option is provided, because it resulted in error.

if (page_is_zero(at[pfn])) {
    ret = page_pipe_add_hole(pp, vaddr, PP_HOLE_ZERO);
    pages[0]++;
}
,is that ok?
