Add explicit array bounds to the function prototypes for the parameters that didn't already get handled by the conversion to use chacha_state: - chacha_block_*(): Change 'u8 *out' or 'u8 *stream' to u8 out[CHACHA_BLOCK_SIZE]. - hchacha_block_*(): Change 'u32 *out' or 'u32 *stream' to u32 out[HCHACHA_OUT_WORDS]. - chacha_init(): Change 'const u32 *key' to 'const u32 key[CHACHA_KEY_WORDS]'. Change 'const u8 *iv' to 'const u8 iv[CHACHA_IV_SIZE]'. No functional changes. This just makes it clear when fixed-size arrays are expected.
