    stdio.h: don't expose rsize_t unless __EXT1_VISIBLE
    
    This is how the other typedefs for rsize_t handle it (in <stddef.h>,
    <stdlib.h>, and <string.h>).  In particular, we shouldn't have any
    rsize_t if a C environment earlier C11 was requested.
    
    This reapplies b35f0aa4952c, chasing c25e55bcf80b, fixing ports build
    failures following b35f0aa4952c without c25e55bcf80b.
