Block patches for 7.0-rc2:
- Disable GLOBAL_STATE_CODE() assertion for the 7.0 release: We got
  another bug report for this, and we do not have the time to
  investigate before 7.0, so disable the assertion for the release, to
  re-enable and continue investigation in the 7.1 cycle

- stream job fix (regarding interaction with concurrent block jobs)

- iotests fixes
