pw_kvs: Functions for updating and copying entries

- The Update function changes the magic, checksum, and transaction ID
  for an entry.
- The Copy function copies an entry from one address to another,
  potentially updating the format in the process.
- Rename checksum_ to checksum_algo_ to differentiate it from the
  calculated checksum.
