Re-optimize counter-mode: save about 15% on my core2 by (1) not regenerating the entire counter buffer every time we encrypt a block of keystream (2) using the platform-optimized htonl to convert to big-endian (It's a single instruction on 486 and later ) and (3) not even keeping a separate "counter" and "buffer" when the platform is big-endian. The third still needs testing.
