RFR: 8098581 SecureRandom.nextBytes() hurts performance with small size requests

[Anthony Scarpino]

Hi all,

I'd like a review of this change.  It improves nextBytes() performance 
by allowing the random buffer to grow and shrink as random data is 
needed and remove the high level synchronization.  Also disable 
SecureRandom for Solaris PKCS11 as it's not as fast as native.
