This patch adds the first ebtables extension to ebtables-compat.
The original 802_3 code is adapted to the xtables environment.
I tried to mimic as much as possible the original ebtables code paths.
With this patch, ebtables-compat is able to send the 802_3 match to the kernel,
but the kernel-to-userspace path is not tested and should be adjusted
in follow-up patches.

Renaming of chains is not working. and ebtables-compat gets:
libnftnl: attribute 0 assertion failed in chain.c:159
This patch brings back the parser code of the original ebtables tool:
http://git.netfilter.org/ebtables.old-history/tree/userspace/ebtables2/ebtables.c#n652
I adapted the original parser code to fit in the new environment. Also tried to
keep original error messages as much as possible.

The RETURN default policy is mandatory in user-defined chains.
Builtin chains must have one of ACCEPT or DROP.
So, with this patch, ebtables-compat ends with:
Command: Result:
-L Always RETURN for user-defined chains
-P builtin RETURN Policy RETURN only allowed for user defined chains
-P builtin ACCEPT|DROP ok
-P userdefined RETURN|ACCEPT|DROP Policy XYZ not allowed for user defined chains
-N userdefined ok
-N userdefined -P RETURN|ACCEPT|DROP Policy XYZ not allowed for user defined chains

And introduce fake ebt_entry.
This gets the code in sync in other existing compat tools. This
will likely allow to consolidate common infrastructure.
This code is still quite experimental.

This patch bootstraps ebtables-compat, the ebtables compatibility
software upon nf_tables.

I have also forward port them on top of the current git HEAD, otherwise
compilation breaks.
This bootstrap is experimental, this still needs more work. --Pablo ]
