qed: mark image clean after repair succeeds

The dirty bit is cleared after image repair succeeds in qed_open().
Move this into qed_check() so that all callers benefit from this
behavior when fix=true.

This is necessary so qemu-img check can call .bdrv_check() and mark the...

qemu-img check: Print fixed clusters and recheck

When any inconsistencies have been fixed, print the statistics and run
another check to make sure everything is correct now.

qed: Fix consistency check on 32-bit hosts

The qed_bytes_to_clusters() function is normally used with size_t
lengths. Consistency check used it with file size length and therefore
failed on 32-bit hosts when the image file is 4 GB or more.

Make qed_bytes_to_clusters() explicitly 64-bit and update consistency...

qed: Add support for zero clusters

Zero clusters are similar to unallocated clusters except instead of reading
their value from a backing file when one is available, the cluster is always
read as zero.

This implements read support only. At this stage, QED will never write a...

qed: Consistency check support

This patch adds support for the qemu-img check command. It also
introduces a dirty bit in the qed header to mark modified images as
needing a check. This bit is cleared when the image file is closed
cleanly.

If an image file is opened and it has the dirty bit set, a consistency...
