qcow2: always operate caches in writeback mode

Writethrough does not need special-casing anymore in the qcow2 caches.
The block layer adds flushes after every guest-initiated data write,
and these will also flush the qcow2 caches to the OS.

qcow2: Simplify calculation for COW area at the end

copy_sectors() always uses the sum (cluster_offset + n_start) or
(start_sect + n_start), so if some value is added to both cluster_offset
and start_sect, and subtracted from n_start, it's cancelled out anyway....

qcow2: Fix avail_sectors in cluster allocation code

avail_sectors should really be the number of sectors from the start of
the allocation, not from the start of the write request.

We're lucky enough that this mistake didn't cause any real bug.
avail_sectors is only used in the intialiser of QCowL2Meta:...

qcow2: fix autoclear image header update

The autoclear feature bits can be used for qcow2 file format features
that are safe to "drop" by old programs that do not understand the
feature. Upon opening the image file unknown autoclear feature bits are
cleared and the image file header is rewritten, but this was happening...

qemu-img check -r for repairing images

The QED block driver already provides the functionality to not only
detect inconsistencies in images, but also fix them. However, this
functionality cannot be manually invoked with qemu-img, but the
check happens only automatically during bdrv_open()....

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.

rbd: hook up cache options

Writeback caching was added in Ceph 0.46, and writethrough will be in
0.47. These are controlled by general config options, so there's no
need to check for librbd version.
