VMDK: bugfix, align offset to cluster in get_whole_cluster

In get_whole_cluster, the offset is not aligned to cluster when reading

VMDK: probe for monolithicFlat images

Probe as the same behavior as VMware does.
Recognize image as monolithicFlat descriptor file when the file is text

either 'version=1' or 'version=2'. No space or upper case charactors...

sheepdog: add full data preallocation support

This introduces qemu-img create option for sheepdog which allows the

qemu or even just "qemu-img create -f qcow2 some.img 1G"
causes a kernel warning:

qcow2: Fix in-flight list after qcow2_cache_put failure

If qcow2_cache_put returns an error during cluster allocation and the
allocation fails, it must be removed from the list of in-flight allocations.
Otherwise we'd get a loop in the list when the ACB is used for the next...

vdi: Avoid direct AIO callback

bdrv_aio_* must not call the callback before returning to its caller. In vdi,
this could happen in some error cases. This starts the real requests processing
in a BH to avoid this situation.
