[Qemu-devel] [PULL 6/6] qapi: add query-display-options command |

Add query-display-options command, which allows querying the qemu
display configuration. This isn't particularly useful, except it
exposes QAPI type DisplayOptions in query-qmp-schema, so that libvirt
can discover recently added -display parameter rendernode (commit
d4dc4ab133b). Works around lack of sufficiently powerful command line
introspection.
