FSFS improvements ready for review (first stage)

Hi,

I just finished the process of preparing the "first stage"
of the fsfs improvements with r1504100. It simply splits
up the humungous 12kLOC file into smaller blocks.

A few adjustments / simplifications to the now exposed
internal API functions were made but most textual
changes are purely following renames. Please review
that those changes don't break anything.

I will continue with actual changes to the implementation
immediately on the same branch. When that is complete,
I'll write another call for review.
