Sparse complains about direct access to the 'helper' and timeout members.
Both have __rcu annotation, so use the accessors.
xt_CT is fine, accesses occur before the structure is visible to other
cpus. Switch to rcu accessors there as well to reduce noise.

Access to the hook pointers use correct helpers but the pointers lack
the needed __rcu annotation.

This patch adds a structure to collect all the context data that is
passed to the cleanup iterator.
struct nf_ct_iter_data {
struct net *net;
void *data;
u32 portid;
int report;
};
There is a netns field that allows to clean up conntrack entries
specifically owned by the specified netns.

These no longer register/unregister a meaningful structure so remove it.

No need to specify this in the registration modules, we already
collect all sizes for build-time checks on the maximum combined size.
After this change, all extensions except nat have no meaningful content
in their nf_ct_ext_type struct definition.
Next patch handles nat, this will then allow to remove the dynamic
register api completely.

All extensions except one need 8 byte alignment, so just make that the
default.

Include some headers in files which require them, and remove others

This patch exports nf_ct_set_timeout() and nf_ct_destroy_timeout().
The two functions are derived from xt_ct_destroy_timeout() and
xt_ct_set_timeout() in xt_CT.c, and moved to nf_conntrack_timeout.c
without any functional change.
It would be useful for other users (i.e. OVS) that utilizes the
finer-grain conntrack timeout feature.

The timeout policy is currently embedded into the nfnetlink_cttimeout
object, move the policy into an independent object. This allows us to
reuse part of the existing conntrack timeout extension from nf_tables
without adding dependencies with the nfnetlink_cttimeout object layout.

As, ctnl_untimeout is required by nft_ct, so move ctnl_timeout from
nfnetlink_cttimeout to nf_conntrack_timeout and rename as nf_ct_timeout.

This patch adds the timeout extension, which allows you to attach
specific timeout policies to flows.
This extension is only used by the template conntrack.
