Use (uint8_t *) for buf_(set|get)_u(32|64) instead of (void *)
This helps to uncover incorrect usage when a pointer to uint32_t is
passed to those functions which leads to subtle bugs on BE systems.
The reason is that it's normally assumed that any uint32_t variable
holds its value in host byte order, but using but_set_u32 on it
silently does implicit pointer conversion to (void *) and the
assumption ends up broken without any indication.
