[PATCH v4 11/16] block/io: support int64_t bytes in bdrv_aligned_pwritev()

We are generally moving to int64_t for both offset and bytes parameters on all io paths. Main motivation is realization of 64-bit write_zeroes operation for fast zeroing large disk chunks, up to the whole disk. We chose signed type, to be consistent with off_t (which is signed) and with possibili
