Version are now returned with major/minor packed into 32-bits, so 0x00020001 is the current disk version, for example. 1. This needed to change to use a disk_* prefix for consistency with the defines that already exist for LFS_VERSION/LFS_DISK_VERSION. 2. Encoding the version this way has the nice side effect of making 0 an invalid value. This is useful for adding a similar config option that needs to have reasonable default behavior for backwards compatibility. In theory this uses more space, but in practice most other config/status is 32-bits in littlefs. We would be wasting this space for alignment anyways.
