This patchset adds reconnect support for vhost-user-scsi. At the same
times, fix vhost fd leak and refactor some code.

Changes for v3:
- Split the vhost_user_scsi_handle_output to a separate patch;
- Move the started_vu from vhost scsi common header to vhost-user-scsi header;
- Fix a log print error;

Changes for v2:
- Split the v1 patch to small separate patchset;
- New patch for fixing fd leak, which has sent to reviewers in another
  mail;
- Implement the `vhost_user_scsi_handle_output`;
- Add the started_vu safe check;
- Fix error handler;
- Check the inflight before set/get inflight fd.

Li Feng (5):
  vhost: fix the fd leak
  vhost-user-common: send get_inflight_fd once
  vhost: move and rename the conn retry times
  vhost-user-scsi: support reconnect to backend
  vhost-user-scsi: start vhost when guest kicks
