We should use proxy headers (redirecting headers in hdr/) in `src/` directory. But... given that these types are non-standard I wonder if you need these headers at all (given that there's no alternative for `__scandir_compare_t` in system libc in overlay mode.

E.g. maybe you'll need to resort to just using `int (*filter)(const struct dirent *)` here. Is there a strong reason to export `__scandir_filter_t` from generated header as a type?
