Therefore, calling 'blockdev-job-finalize' a second time on an already concluded job causes an assertion failure. Remove job->txn from the assertion in block_job_finalize() to fix this. block_job_do_finalize() still has the same assertion, but if a job is already removed from its transaction, block_job_apply_verb() will already error out before we run into that assertion.

For now, Job only stores its ID and JobDriver, the rest stays in BlockJob. The following patches will move over more parts of BlockJob to Job if they are meaningful outside the context of a block job.

In order to keep calling the BlockJob cleanup code when the job is deleted via job_unref(), introduce a new JobDriver.free callback. Every block job must use block_job_free() for this callback, this is asserted in block_job_create().

This includes primarily entering the coroutine (both for the first and reentering) and yielding explicitly and at pause points.

For the moment, these functions only call a notifier in the BlockJob layer that sends the existing commands. This uses notifiers rather than JobDriver callbacks because internal users of jobs won't receive QMP events, but might still be interested in getting notified for the events.

This field makes sense on the Job level, so we can just move it. While at it, rename it to job->force_cancel to make its purpose more obvious. * Resetting the I/O status. This can't be moved because generic Jobs don't have an I/O status. What the function really implements is a user resume, except without entering the coroutine. Consequently, it makes sense to call the .user_resume driver callback here which already resets the I/O status. The old block_job_cancel_async() has two separate if statements that check job->iostatus != BLOCK_DEVICE_IO_STATUS_OK and job->user_paused. However, the former condition always implies the latter (as is asserted in block_job_iostatus_reset()), so changing the explicit call of block_job_iostatus_reset() on the former condition with the .user_resume callback on the latter condition is equivalent and doesn't need to access any BlockJob specific state.

At the same time, this fixes the behaviour to match what the QAPI documentation promises for query-block-job: 'true if the job may be completed'. When the ready flag was introduced in commit ef6dbf1e46e, the flag never had to be reset to match the description because after being ready, the jobs would immediately complete and disappear. Job transactions and manual job finalisation were introduced only later. With these changes, jobs may stay around even after having completed (and they are not ready to be completed a second time), however their patches forgot to reset the ready flag.

As such they make a lot of sense in generic Jobs. This patch moves the fields to Job and renames them to .progress_current and .progress_total to describe their function better.
