Now, struct nf_expect takes only 192 bytes, instead of 1KB.
struct nf_conntrack takes 296 bytes instead of 328 bytes.
The size of the nf_expect structure has been reduced by rearranging
the layout of the nf_conntrack structure. For the nf_conntrack case,
this removes the allocation of room for attributes that the master
tuple does not use (more specifically, the NATseq bytes).
This patch modifies the binary layout of struct nf_conntrack.
This should not be a problem since the definition of this
object is opaque (it can be only accessed via get/set API).

This patch is *not* changing the licensing terms of this library (which
was initially released under GPLv2 and later on extended to GPLv2+ after
contacting all the contributors who kindly agreed to extend it to any
later GPL version).
Jan says: "In libnetfilter_conntrack, there are many .c files declaring
GNU GPL incorporated herein by reference without telling which version(s)
exactly apply. Given src/main.c for example is actually GPL-2.0+,
the reference made is ambiguous."
This patch should definitely clarify this.

This patch adds the size of the arrays to set to NULL unset
elements. This helps to spot unset functions for new attributes.

This new API allows you to set and get some logical set of
attributes. This is not intended to replace the existing
per-attribute get/set API but to provide more efficient way
to get/set certain attributes. This change includes an example
file (conntrack_grp_create.c) of the use of the attribute group API.
See ATTR_GRP_* for more information on the existing groups.
