ui: add a D-Bus display backend
The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.
By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.
The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.
The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:
$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0
org.qemu.Display1.Console interface - - -
.RegisterListener method h - -
.SetUIInfo method qqiiuu - -
.DeviceAddress property s "pci/0000/01.0" emits-change
.Head property u 0 emits-change
.Height property u 480 emits-change
.Label property s "VGA" emits-change
.Type property s "Graphic" emits-change
.Width property u 640 emits-change
[...]
See the interfaces XML source file and Sphinx docs for the generated API
documentations.
