[PATCH v2 0/3] Fix some AIO context locking in jobs

[Stefan Reiter]

Contains three seperate but related patches cleaning up and fixing some
issues regarding aio_context_acquire/aio_context_release for jobs. Mostly
affects blockjobs running for devices that have IO threads enabled AFAICT.

This is based on the discussions here:
https://lists.gnu.org/archive/html/qemu-devel/2020-03/msg07929.html

I *think* the second patch also fixes the hangs on backup abort that I and
Dietmar noticed in v1, but I'm not sure, they we're somewhat intermittent
before too.

Changes from v1:
* fixed commit message for patch 1
* added patches 2 and 3

Stefan Reiter (3):
  backup: don't acquire aio_context in backup_clean
  job: take each job's lock individually in job_txn_apply
  replication: acquire aio context before calling job_cancel_sync
