Do not cast unused return values to void

A small style fix that removes all remaining "(void)" casts. Using these

purpose, except for satisfying a few static code analysis tools. We

should fix what's left:

    identifier func;

    - (void)func (
    + func (
    ...);

Long lines were re-formatted manually.
