Convert 'zstring ptr' args of error-reporting functions to 'const zstring ptr', for consistency with C versions of these declarations

But I'm not planning to use const zstring ptr in general. In my experience (in
C++), getting constness right is a big time sink and pain with very little
chance of catching an actual bug
