explict export lists
Eliminated some dead code. In other cases, exported a currently unused
function, since it was a logical part of the API.

Of course this improves the API documentation. It may also sometimes
let ghc optimize code better, since it can know a function is internal
to a module.

364 modules still to go, according to
git grep -E 'module [A-Za-z.]+ where'
