Switch to packaging model where each module goes into separate package.
Such model makes much more sense (after all it's also how big platforms
such as python do it). It allows better control over dependencies and
allows re-locating modules properly according to compatibility level
(i.e. now exit.sh can go to 'sh' despite the fact that in 'core' it had
to be with other Bash-compatible modules).
