Add ublk stripe target which can take 1~4 underlying backing files or block device, with stripe size 4k ~ 512K. Add two basic tests(write verify & mkfs/mount/umount) over ublk/stripe. This target is helpful to cover multiple IOs aiming at same fixed/registered IO kernel buffer. It is also capable of verifying vectored registered (kernel)buffers in future for zero copy, so far it isn't supported yet. Todo: support vectored registered kernel buffer for ublk/zc.
