netfilter: netns ebtables: part 2
* return ebt_table from ebt_register_table(), module code will save it into
per-netns data for unregistration
* duplicate ebt_table at the very beginning of registration -- it's added into
list, so one ebt_table wouldn't end up in many lists (and each netns has
different one)
* introduce underscored tables in individial modules, this is temporary to not
break bisection.
