Mixing of types in siphash24.c

[Joachim Strömbergson]

siphash24.c contains an of #include <stdint.h>, but then typedef to:
uint64_t u64; typedef uint32_t u32; typedef uint8_t u8;

And then define the function as:
int siphash( unsigned char *out, const unsigned char *in, unsigned long long inlen, const unsigned char *k )

How about just use stdint.h defined types as is?
