John Baldwin 9b6b2f8608 Adjust crypto_apply function callbacks for OCF.
- crypto_apply() is only used for reading a buffer to compute a
  digest, so change the data pointer to a const pointer.

- To better match m_apply(), change the data pointer type to void *
  and the length from uint16_t to u_int.  The length field in
  particular matters as none of the apply logic was splitting requests
  larger than UINT16_MAX.

- Adjust the auth_xform Update callback to match the function
  prototype passed to crypto_apply() and crypto_apply_buf().  This
  removes the needs for casts when using the Update callback.

- Change the Reinit and Setkey callbacks to also use a u_int length
  instead of uint16_t.

- Update auth transforms for the changes.  While here, use C99
  initializers for auth_hash structures and avoid casts on callbacks.
