Unfortunately, while <stddef.h> is defined to specify size_t it
isn't specified to include ssize_t - and many things that need
size_t also need ssize_t (which includes src/usr.bin/tprof one of
the users of <sys/rbtree.h>)

All of this is horribly ugly - perhaps we'd do better to remove
stuff from <sys/types.h> that shouldn't be there (which is probably
any definition which doesn't end in _t except probably the old u_char
u_short ... and their uchar/ushort/... variants).   In particular
I doubt that <sys/types.h> should really be including <machine/endian.h>
and almost certainly not <sys/cdefs.h>, and shouldn't have prototypes
for any functions at all.
