[PATCH v2 0/6] parallels: load bitmap extension

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Hi all!

We need to load bitmaps from parallels image in our product.
So here is a feature.

v2:
01: tweak commit message, add r-bs by Eric and Denis
02: tweak wording by Denis's suggestions
03: new, suggested by Denis
04: rebase on 03, add several error checking,
    convert l1 table to cpu from small-endian,
    allow loading several bitmaps
06: add copyright, drop "/work/mega"

Vladimir Sementsov-Ogievskiy (6):
  qcow2-bitmap: make bytes_covered_by_bitmap_cluster() public
  parallels.txt: fix bitmap L1 table description
  block/parallels: BDRVParallelsState: add cluster_size field
  parallels: support bitmap extension for read-only mode
  iotests.py: add unarchive_sample_image() helper
  iotests: add parallels-read-bitmap test
