Starting from Linux 4.1 allows iov_iter with bio_vec to be passed into iter_read/iter_write. Notably, the loop device will pass bio_vec to backend filesystem. However, current ZFS code assumes iovec without any check, so it will always crash when using loop device. With the restructured uio_t, we can safely pass bio_vec in uio_t with UIO_BVEC set. The uio* functions are modified to handle bio_vec case separately. The const uio_iov causes some warning in xuio related stuff, so explicit convert them to non const.
