Patrick Fallberg 963a756605 sha204 library extended with CRC calculator
Locking operations are recommended to include CRC
and since sha204 library internally carries the proper
algorithm for this, it has now been refactored to support
both static and incremental calculations needed for both
command marchalling and locking.

ATSHA204 is a crypto cirquit from Atmel that enables
SHA256-based MAC and HMAC calculations as well as
secure key storage and random number generation.

This can be used to sign messages passed between
sensor nodes and prevent both man-in-the-middle and
replay attacking.
