[CRIU] [PATCH CRIU 00/14] net/ipv6: c/r dev/default/all conf ops

[Pavel Tikhomirov]

These patch set introduces support of another part of network
sysctls, now for ipv6.

Most important things:
- DEVCONFS_UNUSED=-1 is wrong, use bitmasks, -1 is valid value for
restore now
- mtu, forwarding, disable_ipv6 need special care on restore and in
tests
- add ranges for sysctl values in tests instead of just one limit,
also fix ranges for some sysctls
