[PATCH v2 0/4] qcow2: Misc BDRV_SECTOR_SIZE updates |

This small series gets rid of all the remaining instances of hardcoded
sector sizes in the qcow2 code and adds a check for images whose
virtual size is not a multiple of the sector size.
See the individual patches for details.
Berto
v2:
- Modify output of iotest 080 to make it easier to understand [Nir]
- Use the QEMU_IS_ALIGNED() macro instead of the modulus operator [Nir]
- Tighten some assertions [Kevin]
v1: https://lists.gnu.org/archive/html/qemu-block/2020-01/msg00139.html
Alberto Garcia (4):
qcow2: Require that the virtual size is a multiple of the sector size
qcow2: Don't round the L1 table allocation up to the sector size
qcow2: Tighten cluster_offset alignment assertions
qcow2: Use BDRV_SECTOR_SIZE instead of the hardcoded value
