    <sys/errno.h>: Use __BSD_VISIBLE instead of !_POSIX_SOURCE.
    
    _POSIX_SOURCE is no longer set since it was superseded by
    _POSIX_C_SOURCE. In other words, #ifndef _POSIX_SOURCE is
    always true, unless IEEE Std 1003.1-1988 is explicitly
    requested.
    
    While here, clean up the visibility of all errno defines.
    Those not mentioned in any standard are __BSD_VISIBLE now.
    We can further restrict the standard ones at some later
    point.
