[PATCH RFC v3 0/1] the org.qemu.Display1.UIInfo interface design

Currently, the `SetUIInfo` method cannot set a refresh rate.
Simply adding a refresh_rate argument would break the method signature.

This RFC adds the `UIInfo` interface containing
  * properties as staged display settings.
  * property `Supported` indicating whether console UI info is supported.
  * the method `Apply` applying staged settings.
  * the method `Reload` reloading settings from the console.

Changes since v2:
  * added a read-only bool property "Supported" on the interface.
  * switched to typesafe getter & setter.
  * documented each property/method individually.

Test results:
  * qemu:qtest-x86_64/dbus-display-test passed
  * qemu:qtest-x86_64/dbus-vmstate-test passed
  * qemu:qtest-x86_64/dbus-vnc-test SKIP
  * manually created a virtual machine
    and successfully set its refresh rate and resolution via `UIInfo`
  * sphinxdocs build passed
