nft: bootstrap ebtables-compat

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

[ Original patches:

  http://patchwork.ozlabs.org/patch/395544/
  http://patchwork.ozlabs.org/patch/395545/
  http://patchwork.ozlabs.org/patch/395546/

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 ]
