[0/9] parallels: Refactor the code of images checks and fix a bug

Message

Alexander Ivanov Aug. 8, 2022, 12:07 p.m. UTC

We will add more and more checks of images so we need to reorganize the code.
Put each check to a separate helper function with a separate loop.

Replace qemu_co_mutex_lock by WITH_QEMU_LOCK_GUARD for more clean code.

Fix a bug when out of image offset in BAT leads to image inflation.

Replace bdrv_co_pwrite_sync by bdrv_co_flush for writing to the disk
only dirty blocks.

Merge parallels_check_fragmentation to parallels_collect_statistics.
