Kevin Wolf 3fb588a0f2 block/create: Mark blockdev-create stable
We're ready to declare the blockdev-create job stable. This renames the
corresponding QMP command from x-blockdev-create to blockdev-create.

Kevin Wolf e5ab4347f9 block/create: Make x-blockdev-create a job
This changes the x-blockdev-create QMP command so that it doesn't block
the monitor and the main loop any more, but starts a background job that
performs the image creation.

The basic job as implemented here is all that is necessary to make image
creation asynchronous and to provide a QMP interface that can be marked
stable, but it still lacks a few features that jobs usually provide: The
job will ignore pause commands and it doesn't publish more than very
basic progress yet (total-progress is 1 and current-progress advances
from 0 to 1 when the driver callbacks returns). These features can be
added later without breaking compatibility.

Kevin Wolf b0292b851b block: x-blockdev-create QMP command
This adds a synchronous x-blockdev-create QMP command that can create
qcow2 images on a given node name.

We don't want to block while creating an image, so this is not the final
interface in all aspects, but BlockdevCreateOptionsQcow2 and
.bdrv_co_create() are what they actually might look like in the end. In
any case, this should be good enough to test whether we interpret
BlockdevCreateOptions as we should.
