[CRYPTO]: Add i586 optimized AES
Below is an updated version of patch from Fruhwirth which integrates the
Gladman AES code into the crypto API.
I've tried to ensure that this is done as simply as possible: the user
gets the asm version by default if it's suitable.
I've also now added the alternate GPL licensing provided by Brian Gladman,
and licensed the code as GPL.
