Update the pair_config() parser to follow suite. When the configuration 'lcp-auto-subint' is set, and the interface at hand is a subinterface, in lcp_itf_interface_add_del(): - if it's a deletion and we're a sub-int, and we have a LIP: delete it. - if it's a creation and we're a sub-int, and our parent has a LIP, create one. Fix a few logging consistency issues (pair_del), and in pair_delete_by_index() ensure that the right namespace is selected. Due to this quirk with lip->lip_namespace not wanting to be a vec_dup() string, rewrite them all to be strdup/free instead.
