Gets the canonical file name from filename. All triple slashes are turned into
single slashes, and all .. and .s resolved against relative_to.
Symlinks are not followed, and the returned path is guaranteed to be absolute.
If filename is an absolute path, relative_to is ignored. Otherwise,
relative_to will be prepended to filename to make it absolute. relative_to
must be an absolute path, or NULL. If relative_to is NULL, it'll fallback
to g_get_current_dir().
This function never fails, and will canonicalize file paths even if they don't
exist.
