9ee45d4e34 Fix sign bug in special cases in mpi_{add,sub}_abs(). 
We failed to clear the negative flag when handling trivial cases, so if one of the terms was 0 and the other was negative, the result would be an exact copy of the non-zero term instead of its absolute value.

c6536641c5 Major cleanup of the MD and SHA digests. 
- Use the new vector byte-order conversion functions where appropriate.
- Use memset_s() instead of memset() where appropriate.
- Use consistent names and types for function arguments.
- Reindent, rename and reorganize to conform to Cryb style and idiom.

SHA224 and SHA256 were left mostly unchanged.  MD2 and MD4 were completely rewritten as the previous versions (taken from XySSL) seem to have been copied from RSAREF.

This breaks the ABI as some context structures have grown or shrunk and some function arguments have been changed from int to size_t.

239ab3a471 Implement double- and triple-DES. 
Single-DES is now a special case of triple-DES with all three keys being the same.  This is significantly slower than a pure single-DES implementation, but that's fine since nobody should be using it anyway.

c2f4fa524f Second iteration of the cryb-cipher API. 
We now have separate encryption and decryption methods, and can process an arbitrary amount of plaintext or ciphertext per call, rounded down to the block size (if applicable).  For stream ciphers, we also have a keystream method which fills the provided buffer with an arbitrary amount of keystream (once again, rounded down if applicable).
