qemu-img: There is more than one host device driver

I haven't heard yet of anyone using qemu-img to copy an image to a real floppy,

Don't leak file descriptors

We're leaking file descriptors to child processes. Set FD_CLOEXEC on file
descriptors that don't need to be passed to children to stop this misbehaviour.

qcow2: Store exact backing format length

Currently qcow2 unnecessarily rounds up the length of the backing format string
to the next multiple of 8. At the same time, the array in BlockDriverState can
only hold 15 characters, so in effect backing formats with 9 characters or more...

Images with disk size 0 may be used for
VM snapshots, but not to save normal block data.

It is possible to create such images using

So even "qemu-img info image.qcow2" is not...

Remove aio_ctx from paio_* interface

The context parameter in paio_submit isn't used anyway, so there is no reason

Add qemu_aio_process_queue()

We'll leave some AIO completions unhandled when we can't call the callback.
qemu_aio_process_queue() is used later to run any callbacks that are left and
can be run then.

Revert "qcow2: Bring synchronous read/write back to life"
