When units were initially defined having each on their own line was
compact, since them more fields have been added, making the lines
overly long and the difference between each field non-obvious.
Further, the conversion from C to C++ [0], wrapped definitions onto the
same line (for some reason), resulting in lines over 700 wide.
Use clang-format & add struct ID's for clarity.
