AES bitsliced implementation that is cache attack safe. Configure with: --enable-aes-bitslice or define: WC_AES_BITSLICE HAVE_AES_ECB HAVE_AES_DIRECT Very slow for CBC, CFB, OFB and any mode that uses a previous encrypt block to calculate current. CTR, GCM, XTS can parallelize the data and be much faster. Added AES-ECB test to test.c.

Description
AES bitsliced implementation that is cache attack safe. Configure with:
--enable-aes-bitsliced
or define:
WC_AES_BITSLICED
HAVE_AES_ECB
HAVE_AES_DIRECT
Very slow for CBC, CFB, OFB and any mode that uses a previous encrypt block to calculate current.
CTR, GCM, XTS can parallelize the data and be much faster.
Added AES-ECB test to test.c.
