Byte-boundary prefix detection was too sloppy: Any data following the
first zero-byte was ignored. Add a follow-up loop making sure there are
no stray bits in the designated host part.

Merge scripts for iptables and ip6tables, they were widely identical.
Also extend the test by one check (removing a non-existent rule with
valid chain and target) and quote the error messages where differences
are deliberately ignored.

This patch updates the parser to generate a list of command objects.
This list of commands is then transformed to a list of netlink jobs.
This new command object stores the rule using the nftnl representation
via nft_rule_new().
To reduce the number of updates in this patch, the nft_*_rule_find()
functions have been updated to restore the native representation to
skip the update of the rule comparison code.

Make sure return codes match legacy ones at least for a few selected
commands typically used to check ruleset state.

To be consistent with legacy iptables, calling -S with a non-existing
chain should lead to an error message. This is how some scripts find out
whether a user-defined chain exists or not.
Make sure doing the same for an existing chain does succeed, even if an
invalid rule number was given.

Legacy ip{,6}tables prints feedback for various commands if in verbose
mode, make sure nft variants do the same.
There is one difference, namely when checking a rule (-C command):
Legacy ip{,6}tables print the rule in any case, nft variants don't in
case the rule wasn't found. Changing this though would require to
populate the nftnl_rule object just for printing, which is probably not
feasible.
