[Max Reitz <mreitz@redhat.com>]

This series adds support to qemu-img, block and qcow2 for amending image
options on existing image files.

Depends on:
 - option: Add assigned flag to QEMUOptionParameter
 - qcow2-refcount: Snapshot update for zero clusters

v2:
 - Generally implemented Kevin's comments, especially:
   - Zero cluster expansion for inactive L2 tables
   - Correct handling of preallocated zero clusters
   - More test cases

Max Reitz (3):
  block: Image file option amendment
  qcow2: Implement bdrv_amend_options
  qemu-iotest: qcow2 image option amendment
