netfilter: updates for net

This is a much earlier pull request than usual, due to the large
backlog.  We are aware of several unfixed issues, in particular
in ctnetlink, patches are being worked on.

The following patchset contains Netfilter fixes for *net*:

1) fix a use-after-free in ctnetlink, from Hyunwoo Kim, broken
   since v3.10.
2) add missing netlink range checks in ctnetlink, broken since v2.6
   days.
3) fix content length truncation in sip conntrack helper,
   from Lukas Johannes Möller.  Broken since 2.6.34.
4) Revert a recent patch to add stronger checks for overlapping ranges
   in nf_tables rbtree set type.
   Patch is correct, but several nftables version have a bug (now fixed)
   that trigger the checks incorrectly.
5) Reset mac header before the vlan push to avoid warning splat (and
   make things functional). From Eric Woudstra.
6) Add missing bounds check in H323 conntrack helper, broken since this
   helper was added 20 years ago, from Jenny Guanni Qu.
7) Fix a memory leak in the dynamic set infrastructure, from Pablo Neira
   Ayuso.  Broken since v5.11.
8+9) a few spots failed to purge skbs queued to userspace via nfqueue,
   this causes RCU escape / use-after-free. Also from Pablo. broken
   since v3.4 added the CT target to xtables.
10) Fix undefined behaviour in xt_time, use u32 for a shift-by-31
    operation, not s32, from Jenny Guanni Qu.
11) H323 conntrack helper lacks a check for length variable becoming
    negative after decrement, causes major out-of-bounds read due to
    cast to unsigned size later, also from Jenny.
    Both issues exist since 2.6 days.
