[Libguestfs] [libnbd PATCH 0/2] NBD_OPT_INFO support

[Eric Blake]

This replaces 13/13 of my v2 series; and now that it has pretty good
testsuite coverage and demonstrable performance improvement to
nbdinfo, I'm going ahead and pushing this now.  We may still want to
add further nbd_opt_* commands for other fine-grained tuning of
negotiation, but for now, I think things have stabilized on this end,
and I can return to polishing .list_exports on the nbdkit end.

Eric Blake (2):
  api: add nbd_opt_info, nbd_aio_opt_info
  info: Use nbd_opt_info for fewer handles during --list
