Big bundle commit: adjust build project skeleton; include uncommitted code

There was some code that was being slowly tweaked as I'd work or related
things on other repositories that wasn't committed step by step, and
that now I'd rather include all as a single changeset, single there
weren't really separated stages on how it was developed.

Other than that, this commit includes adjustments on dependencies API
usage, as they changed during my work on them, and adjustments on the
build and test system, as I improved how they worked also during work on
other projects.

As of this commit, the code compiles and the tests pass.  I can't recall
if this was true before this commit, but it is true now.
