Fix ChaCha20 on 32-bit platforms (#99)
* Fix ChaCha20 on 32-bit platforms
On 32-bit platforms with old compiler STORE64H() parameter is
not auto-expanded to 64-bit value, causing wrong IV data.
Spotted on BCM4706 MIPS32r2 with GCC 4.2.4:
Exit before auth: Integrity error (bad packet size 2065808956)
* Fix Chacha20-Poly1305 and AES-GCM debug messages
Functions were renamed earlier and trace messages - not.
