Auto loading bitmaps are bitmaps in Qcow2, with the AUTO flag set. They
are loaded when the image is opened and become BdrvDirtyBitmaps for the
corresponding drive.
Extra data in bitmaps is not supported for now.

If explicit zeroing out before mirroring is required for the target image,
it moves the block job offset counter to EOF, then offset and len counters
count the image size twice. There is no harm but stats are confusing,

This is not as bad as I thought it would be.
Only two cases: type == base_type and type != base_type.

Sometimes the target architecture may allow some parts of a register to be
accessed as a different register. If both of these registers are
implemented as globals in QEMU, then their content will overlap and the
change to one global will also change the value of the other. To handle
