Lots of typos above.

That's just doing an indirect source local value -> full list (#defines
only) mapping.
Then on vout usage use a common helper for #defines -> Surjective
mapping to local.
Where the current way does Surjective mapping at source, and sometimes
another remapping in vout.

That keeps the original values untouched for sout and eases mapping in
all other modules.
