    crypto/chacha20: Multiple minor tweaks and cleanups
    
    - Use 'uint32_t' instead of 'u_int'.
    - Use 'ifdef' instead of 'ifndef' for CHACHA_NONCE0_CTR128 to improve
      readability.
    - Add 'chacha_ctrsave()' prototype to the header.
    - Remove unnecessary header inclusions.
    - Remove unnecessary CHACHA_UNUSED define.
    - Remove useless '$FreeBSD$' tag.
    - Minor whitespace cleanups to look better.
    
    No functional change.
