    libc: Change dirfd() into a function (needed per POSIX).
    
    At the same time, make struct _dirdesc private to libc. If access
    to dd_fd is needed, dirfd() has to be used. Inside libc, the former
    dirfd() macro is preserved as _dirfd().
    
    Also, in struct _dirdesc, change the lock from "void *" to
    "struct pthread_mutex *". This allows us to eliminate some casts
    in readdir() and friends.
    
    Our documentation already describes dirfd() as a function.
    
    Based-on: FreeBSD's similar work
