Each clock domain needs a separate reset line.
However, one cannot reset only a single domain---that could cause inconsistency
at clock crossing boundaries.
This change splits reset lines per clock domain and centralizes generation.

Updated uses of the wishbone_pkg to use Tom's naming conventions.
Added Manifests for the new files.
