    Drop redundant arc4random prototypes from cygwin/stdlib.h
    
    Newlib's default stdlib.h now defines these functions so we can
    drop them from the Cygwin-specific header.  Remove the arc4random_stir
    and arc4random_uniform prototypes entirely.  They shouldn't be used
    by applications anymore.
