Basic idea is to split first loop in two, and run checks before making anything actually local, to detect data-blocks that we can directly make local (because we are sure they are only used by already/future local datablocks). This allows to avoid a lot of overhead in later 'cleanup' steps of this function, here with barbershop shot it's four times quicker (from 190s to 48s). We are still far from the instantaneous results of MakeLocal in 2.77, but in that version main characters lose their connection to their armature and remain static after makelocal, so guess new code is still better. ;) There are probably more optimizations possible here, but would rather polish this area of code once we get rid of proxies, those really make it a nightmare to work on.
