John Snow 111049a4ec blockjob: refactor backup_start as backup_job_create ... Refactor backup_start as backup_job_create, which only creates the job, but does not automatically start it. The old interface, 'backup_start', is not kept in favor of limiting the number of nearly-identical interfaces that would have to be edited to keep up with QAPI changes in the future. Callers that wish to synchronously start the backup_block_job can instead just call block_job_start immediately after calling backup_job_create. Transactions are updated to use the new interface, calling block_job_start only during the .commit phase, which helps prevent race conditions where jobs may finish before we even finish building the transaction. This may happen, for instance, during empty block backup jobs.
