[PATCHv2] Emit graphics events when a SPICE client connects/disconnects

[Laine Stump <laine@xxxxxxxxx>]

Wire up the domain graphics event notifications for SPICE. Adapted
from a RHEL-only patch written by Dan Berrange that used custom
__com.redhat_SPICE events - equivalent events are now available in
upstream QEMU (including a SPICE_CONNECTED event, which was missing in
the __COM.redhat_SPICE version).

* src/qemu/qemu_monitor_json.c: Wire up SPICE graphics events
---

V2: fix copy-paste typos checking for wrong strings.
    Not adding any interpretation of parameters, as this patch
    is just achieving parity with RHEL-specific build.
