the length to a size_t to match the other CRC functions.

crc: add a faster, chainable version of CRC16/CCITT.
...
The existing version of crc16_ccitt() is actually CRC-16/AUG-CCITT and
gives different results to Linux, Contiki, and the CRC unit in the
SAM0 SOC. This version matches Linux.
Note that this is an incompatible API change.
