`WANT_IDN_PROTOTYPES` was necessary to avoid using a header that came via an optional package. MS stopped distributing this package some years ago and the winidn definitions are part of standard headers (via `windows.h`) since Vista. Auto-detect Vista inside `lib/idn_win32.c` and enable the manual definitions if building for an older Windows. This allows to delete this manual knob from all build-systems. Also drop the `_SAL_VERSION` sub-case: Our manual definitions are now only enabled with old systems. We assume that code analysis is not run on such systems, allowing us to delete the SAL-friendly flavour of these. Reviewed-by: Jay Satiro Closes #9793
