Move sanitary_path_copy() to path.c and rename it to normalize_path_copy()

This function and normalize_absolute_path() do almost the same thing. The
former already works on Windows, but the latter crashes.

In subsequent changes we will remove normalize_absolute_path(). Here we
make the replacement function reusable. On the way we rename it to reflect
that it does some path normalization. Apart from that this is only moving
around code.
