CAMELLIA-CFB128 buffer encryption/decryption.
Note: Due to the nature of CFB you should use the same key schedule for both encryption and decryption. So a context initialized with mbedtls_camellia_setkey_enc() for both MBEDTLS_CAMELLIA_ENCRYPT and CAMELLIE_DECRYPT.

CAMELLIA-CTR buffer encryption/decryption.
Warning: You have to keep the maximum use of your counter in mind!
Note: Due to the nature of CTR you should use the same key schedule for both encryption and decryption. So a context initialized with mbedtls_camellia_setkey_enc() for both MBEDTLS_CAMELLIA_ENCRYPT and MBEDTLS_CAMELLIA_DECRYPT.
| ctx | CAMELLIA context |
| length | The length of the data |
| nc_off | The offset in the current stream_block (for resuming within current cipher stream). The offset pointer to should be 0 at the start of a stream. |
| nonce_counter | The 128-bit nonce and counter. |
| stream_block | The saved stream-block for resuming. Is overwritten by the function. |
