8b19ae0761 crc: fix signed overflow 
This fixes a signed overflow from i << 24 when i == 255 by
making i unsigned.  The result of the shift is already
assigned to an variable of unsigned type.

b3e144a7df des: add possibility to calculate DES-CBC-MAC with small buffer 
This patch adds the possibility to calculate the DES-CBC-MAC of a
source buffer (i.e. the last block of the buffer encrypted in CBC
mode) without having to allocate a destination buffer that is as
long as the complete source buffer, but instead only 8 bytes
for the MAC.
