ACK series w/ 2 minor changes (which I made)
  - the 'ndisk' in daemon/remote.c should be a 'size_t' not an 'int'
since it's a copy of the (new) ndevAlias (which is a size_t).
  - Use QEMU_JOB_QUERY not MODIFY since that's what was agreed upon
during v2 review

Also fixed up the (now) merge conflicts w/ the agent lifecycle series
that got pushed before this...

And pushed
