Add the rest of the CRC library functions to kernel-api.

- try to clarify crc32() by adding '@' to a function parameter
- reorder kernel-api CRC functions to be less random
- add more CRC functions to kernel-api
- correct the function parameter names in several places

Add a little helper for crc4 calculations. This works 4-bits-at-a-time,
using a simple table approach.

We will need this in the FSI core code, as well as any master
implementations that need to calculate CRCs in software.
