Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next. Briefly
speaking, cleanups and minor fixes for ipset from Jozsef Kadlecsik and
Serget Popovich, more incremental updates to make br_netfilter a better
place from Florian Westphal, ARP support to the x_tables mark match /
target from and context Zhang Chunyu and the addition of context to know
that the x_tables runs through nft_compat. More specifically, they are:

1) Fix sparse warning in ipset/ip_set_hash_ipmark.c when fetching the
   IPSET_ATTR_MARK netlink attribute, from Jozsef Kadlecsik.

2) Rename STREQ macro to STRNCMP in ipset, also from Jozsef.

3) Use skb->network_header to calculate the transport offset in
   ip_set_get_ip{4,6}_port(). From Alexander Drozdov.

4) Reduce memory consumption per element due to size miscalculation,
   this patch and follow up patches from Sergey Popovich.

5) Expand nomatch field from 1 bit to 8 bits to allow to simplify
   mtype_data_reset_flags(), also from Sergey.

6) Small clean for ipset macro trickery.

7) Fix error reporting when both ip_set_get_hostipaddr4() and
   ip_set_get_extensions() from per-set uadt functions.

8) Simplify IPSET_ATTR_PORT netlink attribute validation.

9) Introduce HOST_MASK instead of hardcoded 32 in ipset.

10) Return true/false instead of 0/1 in functions that return boolean
    in the ipset code.

11) Validate maximum length of the IPSET_ATTR_COMMENT netlink attribute.

12) Allow to dereference from ext_*() ipset macros.

13) Get rid of incorrect definitions of HKEY_DATALEN.

14) Include linux/netfilter/ipset/ip_set.h in the x_tables set match.

15) Reduce nf_bridge_info size in br_netfilter, from Florian Westphal.

16) Release nf_bridge_info after POSTROUTING since this is only needed
    from the physdev match, also from Florian.

17) Reduce size of ipset code by deinlining ip_set_put_extensions(),
    from Denys Vlasenko.

18) Oneliner to add ARP support to the x_tables mark match/target, from
    Zhang Chunyu.

19) Add context to know if the x_tables extension runs from nft_compat,
    to address minor problems with three existing extensions.

20) Correct return value in several seqfile *_show() functions in the
    netfilter tree, from Joe Perches.
