dirent: push dirent type to prototypes

This syncs the dirent related functions with the glibc behavior -- rather
than take void pointers everywhere, make the struct dirent pointers
explicit in the API.  After all, the functions themselves will cast the
pointers to a dirent structure, so if it isn't as expected, people will
crash.
