[CRIU] [PATCH v6 00/13] 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 SysctlEntrys to track unused 
sysctls
- 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

Changes:

v2: add SysctlEntrys, now can save string sysctls and easier handle unused

v3: rebase images/Makefile to criu-dev branch

v4: use CTL_FLAGS_HAS, use enum for SysctlEntry.type

v5: use CTL_TYPE in sysctl_entries_equal

v6: fix "sysctl: add CTL_FLAGS_HAS to mark successful sysctl_op request"
compilation, net_conf_op: manage non-existing string and fix wrong
sysctl_op arg for string, add rconf.
