This extension breaks when trying to delete rules, add a new revision to
fix this.

commit c33cb0020ee6dd96cc9976d6085a7d8422f6dbed upstream.
Apparently, <linux/netfilter/nfnetlink_cthelper.h> and
<linux/netfilter/nfnetlink_acct.h> could not be included into the same
compilation unit because of a cut-and-paste typo in the former header.

and include <linux/const.h> in UAPI headers instead of <linux/kernel.h>.
The reason is to avoid indirect <linux/sysinfo.h> include when using
some network headers: <linux/netlink.h> or others -> <linux/kernel.h>
-> <linux/sysinfo.h>.
This indirect include causes on MUSL redefinition of struct sysinfo when
included both <sys/sysinfo.h> and some of UAPI headers:

[ Upstream commit 89a26cd4b501e9511d3cd3d22327fc76a75a38b3 ]
When running a 64-bit kernel with a 32-bit iptables binary, the size of
the xt_nfacct_match_info struct diverges.
kernel: sizeof(struct xt_nfacct_match_info) : 40
iptables: sizeof(struct xt_nfacct_match_info)) : 36
Trying to append nfacct related rules results in an unhelpful message.
Although it is suggested to look for more information in dmesg, nothing
can be found there.
# iptables -A <chain> -m nfacct --nfacct-name <acct-object>
iptables: Invalid argument. Run `dmesg' for more information.
This patch fixes the memory misalignment by enforcing 8-byte alignment
within the struct's first revision. This solution is often used in many
other uapi netfilter headers.

[ Upstream commit 0d704967f4a49cc2212350b3e4a8231f8b4283ed ] cgroup v2 path field is PATH_MAX which is too large, this is placing too much pressure on memory allocation for people with many rules doing cgroup v1 classid matching, side effects of this are bug reports like: https://bugzilla.kernel.org/show_bug.cgi?id=200639 This patch registers a new revision that shrinks the cgroup path to 512 bytes, which is the same approach we follow in similar extensions that have a path field.
