Polish API `unsigned char*` vs. `void*`

The discussion started in #171

instead of:

int fnc(const unsigned char *in, unsigned long inlen, unsigned char *out, unsigned long *outlen)
{
   /* some code */
}

use rather:

int fnc(const void *inptr, unsigned long inlen, void *outptr, unsigned long *outlen)
{
   const unsigned char *in = inptr
   unsigned char *out = outptr;
   /* some code */
}

also: in C the proper type for sizes is size_t, not unsigned long. (usually it's the same, but some odd platforms like windows have a 32bit long on 64bit).
