====================
netfilter updates for net-next

1. Prefer KMEM_CACHE() macro to create kmem caches, from Kunwu Chan.

Patches 2 and 3 consolidate nf_log NULL checks and introduces
extra boundary checks on family and type to make it clear that no out
of bounds access will happen.  No in-tree user currently passes such
values, but thats not clear from looking at the function.
From Pablo Neira Ayuso.

Patch 4, also from Pablo, gets rid of unneeded conditional in
nft_osf init function.

Patch 5, from myself, fixes erroneous Kconfig dependencies that
came in an earlier net-next pull request. This should get rid
of the xtables related build failure reports.

Patches 6 to 10 are an update to nftables' concatenated-ranges
set type to speed up element insertions.  This series also
compacts a few data structures and cleans up a few oddities such
as reliance on ZERO_SIZE_PTR when asking to allocate a set with
no elements. From myself.

Patches 11 moves the nf_reinject function from the netfilter core
(vmlinux) into the nfnetlink_queue backend, the only location where
this is called from. Also from myself.

Patch 12, from Kees Cook, switches xtables' compat layer to use
unsafe_memcpy because xt_entry_target cannot easily get converted
to a real flexible array (its UAPI and used inside other structs).
