        libc/stdio     : fclose.c fdevopen.c 

Log message:
        Keep track of streams that have been malloc()ed (via fdevopen()) by
        setting the internal __SMALLOC flag bit.  In fclose(), only free those
        streams that have this bit set, in order to avoid accidentally freeing
        something that has been set up using fdev_setup_stream().
        
        Add fdev_close() as a hook to destroy library data before deleting any
        fdev_setup_stream()-initialized stream objects.  Currently evaluates to
        nothing, but might be used in future versions (e.g. when buffering file
        data).
