Before we can make x-blockdev-create a background job, we need to
generalise the job infrastructure so that it can be used without any
associated block node.

This series extracts a Job object from the block job infrastructure,
which should contain everything related to jobs that doesn't require the
block layer to be involved.

Job creation with a centralised job-create command (if we even want
this) as well as the actual conversion of x-blockdev-create to Job is
left for another series. With 42 patches, the series must be perfect and
I can't add any more patches.

Thanks for the review, applied patches 1-6 in the hope of making v2 at
least a little bit shorter. :-)

Or now you can split/add patches until you're back up to 42 patches in v2 ;)
