[PATCH RFC v4 0/1] the org.qemu.Display1.UIInfo interface design

[Chengyang Zhu <colazcyg@gmail.com>]

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

This patch adds the UIInfo interface containing
  * property `Supported` indicating whether console UI info is supported.
  * the method `Apply` taking a dictionary as input.
  * the method `Get` returning the current UI info as a dictionary.

Changes since v3:
  * switched back to the dictionary approach.

This patch needs further discussion on:
  * Updated/Changed signal as mentioned before in the v3 email thread.
  * necessary test suite to prevent dictionary schema deviating from QemuUIInfo.

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 `Apply`
