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

[Alberto Garcia <berto@igalia.com>]

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.
