job: Add reference counting
This moves reference counting from BlockJob to 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().
