[RFC qemu 0/6] mirror: implement incremental and bitmap modes

[Fabian Grünbichler]

picking up on John's in-progress patch series from last summer, this is
a stab at rebasing and adding test cases for the low-hanging fruits:

- bitmap mirror mode with always/on-success/never bitmap sync mode
- incremental mirror mode as sugar for bitmap + on-success

Fabian Grünbichler (4):
  mirror: add check for bitmap-mode without bitmap
  mirror: switch to bdrv_dirty_bitmap_merge_internal
  iotests: add test for bitmap mirror
  mirror: move some checks to QMP

John Snow (2):
  drive-mirror: add support for sync=bitmap mode=never
  drive-mirror: add support for conditional and always bitmap sync modes
