[tor-commits] [tor/master] Now that OpenSSL 0.9.8 is dead, crypto_seed_rng() needs no args

commit f8f407d66a4389035852a229a6945cc08a64b198

    Now that OpenSSL 0.9.8 is dead, crypto_seed_rng() needs no args
    
    It needed an argument before because it wasn't safe to call
    RAND_poll() on openssl 0.9.8c if you had already opened more fds
    than would fit in fd_set.
