start modularizing cbt into libraries

this extracts certain parts of cbt into stand-alone libraries, which can
be published to maven and used outside of cbt.

This also adds scalariform for these parts of the code.

This slows down cbt’s own build a lot because of the number of projects
involved! So we’ll follow this by a bunch of performance tweak commits.
