    libc: Replace vis(3) and unvis(3) files with NetBSD versions
    
    * Rendering the corresponding APIs compatible with NetBSD and FreeBSD.
    
    * Keep strnvis() as-is, keeping it compatible with previous DragonFly
      versions, OpenBSD and libbsd
    
    * We already had the original OpenBSD version of strnvis(), which
      predates the NetBSD one by more than 10 years
    
    * New userland utilities code partially obtained from FreeBSD.
