Log: MFC r305679: Switch random_get_pseudo_bytes() shim to arc4rand(). Our shim for Solaris random_get_bytes() uses read_random(), that looks reasonable, since it guaranties reliably seeded random data. On the other side Solaris random_get_pseudo_bytes() does not provide this guarantie, and its original Solaris implementation is equivalent to our arc4rand(), using software crypto without stressing slower hardware RNG.
